Jeep

Note

This is NOT A FULL LIST of features available for modification, rather a colletion of more complex, vehicle-specific settings. For a complete list of features go to the JScan app and use demo mode connection.

Wrangler JK (2007-2018)

Installing LED Fog Lights

JScan can’t help much here, but please see this great guide on installing LED fog lights in your JK.

Sway Bar removal

Note

DO NOT access the Sway Bar module to disable it. That’s not how it works.

1. Go to Adaptation section

2. Use the search and find:

   • ASBS Sway Bar On/Off

3. Disable it

4. Turn the ignition off, restart the vehicle.

In case there are still errors, run Advanced Scan and clear them.

TPMS

Follow the generic TPMS instructions.

US -> EU Light conversion

If you imported a JK from the USA, you will need to adapt (among other things) the rear lights. In American version the stop light is also the turn signal. In Europe, these need to be separated.

1. Connect to your vehicle

2. Open Adaptation

3. Open “Lights conversion US<->EURO & LED”

4. Set “Rear Lighting Combined On/Off” to disabled

Now your side lamps will work as indicators only, and you need to route a wire from the third (central) stop light to each of the rear lamps to power the European stop lights as well.

Transmission gear ratio

Change this only if you physically changed the gears. Make sure you know the actual ratio (don’t trust the labels on boxes).

1. Connect to your vehicle

2. Open Adaptation

3. Open “Tire & Axle Settings”

4. Change T-Case High and/or T-Case Low Ratio

5. Execute Initialize EGS

   Note

   For WA580 - NAG1 automatic transmission only. This step is not required in JK 3.8 with an older transmission (it doesn’t have the EGS).

6. Turn off the vehicle

7. Close & lock the door and leave the vehicle for a 15 min break

8. Go for a test drive

Note

If there are errors mentioning “incorrect gear ratio” see Troubleshooting

Jeep Wrangler JK Automatic transmissions

Below you will find tech tips and procedures dedicated for each gearbox. There were 3 automatic gearboxes in JK 42RLE (4 speed), 545RFE (5 speed), WA580/NAG1 (5 speed)

• JK 2.8 CRD 2007 - 2010 - 545RFE

• JK 2.8 CRD 2010 - 2018 - WA580/NAG1

• JK 3.8 Petrol - 2007-2011 - 42RLE

• JK 3.6 Petrol - 2011 - 2018 - WA580/NAG1

545RFE

The 545RFE transmission has its own transmission control unit Procedures:

• “Quick Learn” - Quick Learn should only be used when a transmission has been replaced or overhauled, or when the Transmission Control Module has been replaced or flashed.

• “Clear VLP Counters” - Shift Counters

• “Clear VLP Counters” - Tooth Counters

42RLE

The 42RLE gearbox has a gearbox controller connected to the engine control unit (all in one module) Procedures:

• “Quick Learn” - Quick Learn should only be used when a transmission has been replaced or overhauled, or when the Transmission Control Module has been replaced or flashed.

• “Clear VLP Counters” - Shift Counters

• “Clear VLP Counters” - Tooth Counters

WA580/NAG1

The WA580 gearbox has its own gearbox control unit (it is roughly to the right of the driver’s feet) Procedures:

• Initialize EGS - This procedure will transfer data in to transmission module, it is required when you update Axle Ratio and recommend with significant Tire Size update (if you experience poor shifting).

• TCM Reset Learned Adaptives - This procedure This program allows the electronic transmission system to re-calibrate itself.

• TCM Store Learned Adaptives - This procedure This program allows the electronic transmission system to save current calibrations.

See NAG1 How-To for details.

Setting the Steering Angle

There is no such thing as an software initialization procedure for the steering angle sensor. If the wheels are straight and the steering column is assembled right, it will read 0.

General hints on handling steering angle issues:

Connect > go to modules > ABS > Live Data > (…) > search for steering angle > select > OK > PLAY

• If your wheels are straight it should show 0

• If it shows 180, the steering column part is upside down

If it is OK - start the engine, make a full turn left, full turn right. Switch back the key to RUN (engine off) > Run Advanced Scan, see if you have any further errors.

If the steering angle is off by a different number than ~180 you’ll have to inspect the steering system.

ABS Pump Bleed

It’s PUMP bleed, not a full brake sytem bleed. It’s to be done after a regular brake bleed.

Note

Yes, it does bleed only one side. By design.

Changing the radiator fan trigger temperature

This is not a setting that can be configured with JScan. There are other tools, which modify the engine controller software / do tuning, that can do it, but this is beyond the scope of JScan app.

Axle Ratio change

Changing the axle ratio works in a similar way on the vehicles that support it. What is important though are the steps AFTER making the changes.

Attention

Make sure your engine is NOT RUNNING

1. Connect to your vehicle

2. Wait for the VIN to be discovered

3. Open Adaptation

4. Open Tire & Axle settings.

5. Open Axle Ratio

6. Read the help (?) if present

7. Choose a value from the drop-down list.

   Note

   If you pick a value that doesn’t match the actual physical gears, you will be getting all sorts of gear ratio errors once you start driving.

8. Tap Go

Once done, follow the steps indicated in the help section. For example, on the JK Wrangler (automatic transmission) this means:

1. Do not drive yet

2. Run the Initialize EGS adaptation

3. Follow the instructions on screen

When procedure is completed turn ignition to off. Leave the car, close & lock the door. Take a 5 min break.

After 5 min, start the car and do a test drive and check if all is fine. If you have any problems, check troubleshooting section.

Notes:

If you’ve installed Dana 60 axles on a model equiped with Dana 30 or 44 model, you will need to consider the difference in ABS tone ring tooth count (60 vs 52).

There are two ways of handling this:

Easier:

You can set the axle ratio & tire size to a value multiplied by 0.86666~ (60/52) to cheat the system. For Example:

Gear Ratio Calculations:

5.38 x 0.8666666666666667 = 4.66 5.13 x 0.8666666666666667 = 4.45 4.88 x 0.8666666666666667 = 4.23

Tire Size Calculations:

42 x 0.8666666666666667 = 36.40 40 x 0.8666666666666667 = 34.67 37 x 0.8666666666666667 = 32.07

More complex:

This method is not 100% confirmed, but theoretically is the proper way to address the tone ring tooth count difference.

After changing the axle ratio and initialising EGS:

1. Go to JScan settings > App & Adapter settings

2. Enable ‘Show advanced adaptations’

3. Restart the app

4. Connect to the vehicle

5. Go to Adaptation > Tire & Axle settings

6. You will see two new adaptations:

• ABS Front Tone Wheel Teeth Count

• ABS Rear Tone Wheel Teet Count

Set both of them to 60

7. Go to Adaptation > Vehicle Maintenance

8. Run ABS Initialization

If successful, turn the ignition to off, lock the door for 5 minutes. Take a break. After 5 minutes, go for a test drive.

Wrangler JL (2018+)

Choosing the right adapter

Jeep JL (and JT) are quite advanced in terms of electronic systems installed in the vehicle. Some of these systems don’t operate on the standard CAN bus network, and to access them you will need either the Vlinker MS or vLinker MC+ OBD or Link MX+ adapter.

The affected modules are:

• HVAC (Heat, Ventilation, Air Conditioning)

• BSM (Blind Spot Module)

• some other radio features

Bypassing the Security Gateway

Chrysler’s Secure Gateway Module came out in 2018. The SGW is a module whose function is simply to keep the communication networks secure. The SGW protects the vehicle networks from being exploited by creating a firewall between two portions of the network with the most vulnerability. This means, that to make any changes, you will need a SGW bypass - usually a cable. See our SGW Bypass page for details.

Changing TPMS thresholds

1. Connect to your vehicle

2. Open Adaptation

3. Open TPMS settings

4. Set TPMS thresholds in the following:

   • Light Load Inflation Pressure Front / Rear Tire: Leave at 0.

   • Max Load Inflation Pressure Front / Rear Tire: This value is used as the minimum pressure. Change this to your liking.

5. Close the car, let it sit for a few minutes, and then go for a test drive and reach minimum of 30mph then system should relearn the new settings.

6. If you see no change in behaviour, continue to the next step:

7. Reset the TPMS. Use !Restart all ecus option:

   • from the drop-down menu choose Tire Pressure Monitor - Power On Restart

   • tap GO

   • once procedure is complete, repeat step 5.

ESS - Engine Start/Stop System

Warning

ESS settings will not work on their own. A small hardware change si required and the warning light for ESS will remain.

To successfully disable the ESS you will need to complete both changes below:

Software settings:

1. Connect to your vehicle in JScan

2. Go to Adaptation > Auto Stop/Start (ESS) Settings and see the following:

   

   1. Auto Start/Stop On/Off - disable this setting to stop the ECU from monitoring the Hood Ajar switch.

   Note

   This will also disable Remote Start feature.

   2. Auto Start/Stop Menu Present On/Off - disable this setting to remove the ESS-related menu entries on your instrument cluster (dashboard).

   Note

   If you don’t want to disable ESS but want to explore any issues with the system, enable this option - it will give you quite a good overview of the system status.

3. Disconnect JScan

4. Turn the vehicle OFF

Hardware mod:

Open the hood and follow the instructions below to disengage the Hood Ajar sensor:

1. The sensors (two of them) are basically simple switches. Located just next to the grille on the left side of the vehicle (on your right, when you stand in front and look at the hood).

2. You need to remove only one of the sensors, but leave it plugged in to the harness

3. On the top side of the sensor, there are two tabs in the ring that mount the sensor to the metal bracket. Press both of them to release the sensor.

4. Pull the sensor up

5. Gently pry the plastic tab that holds the sensor together to disconnect the top part

6. Pull the cable along with the lower part through the metal bracket opening

7. Reassemble the sensor and secure it below & behind the bracket in an extended position (do not squeeze it - you want to simulate the hood open state)

Tire size - Manual transmission

When changing tire size in a JL with a manual transmission it is necessary to follow the procedure below to avoid DTC P08A6 error.

1. Restart the PCM (Power Control Module) by either disconnecting the battery (batteries) or using JScan !Restart all ECUs adaptation

2. Once reset, drive the Jeep so:

   1. Vehicle speed is 40-80mph, in 6th gear

   2. Accelerator pedal position is more than 0.392 volts

   3. Flywheel torque is >75 Nm

3. Drive like this for at least 20 seconds.

4. Once the module reads all the data it will re-enable the all gear sensor performance diagnostic.

Axle ratio - Manual transmission

After changing the axle ratio on a JL with a manual transmission you may need to run the PCM - clutch replacement eeprom reset procedure to prevent the vehicle from entering the limp mode.

Adding dedicated LED DRLs (also to JL Sport)

If you have a Rubicon or Sahara:

Factory fenders have dedicated DRL wires. You need to activate both the outputs for them to work correctly. Also you need to remember that factory DRL are LED.

Required adaptations to change:

Activate: - Left Dedicated DRL Output Present - Right Dedicated DRL Output Present - Day Time Running Lights Present - LED Dedicated DRL Present - DRL Customer Setting - Daytime Running Lights Customer Settings (radio)

Set: - DRL Lamp Location - Dedicated - DRL Configuration- Canada or Europe

The Sport version of JL doesn’t have the DRL wiring in the fenders. The DRL output wires reach the connector to which the fender harness is plugged in, but the fender harness itself doesn’t have the DRL wires, so you will need to add the required wires.

LED lights / indicators warning

The best results are achieved when doing the changes in the following order:

1. Go to Adaptation

2. Navigate to the LED settings group

3. DISABLE “LED xyz Present On/Off” for the type of lights you want to convert to LED if you changed it already

4. Disable the corresponding diagnostics options.

5. Run !Restart All ECUs (PowerOn Restart)

6. Cycle the ignition (turn the Jeep off, wait a few seconds, turn it on to RUN again)

7. Re-connect if necessary

8. Enable “LED xyz Present On/Off” for the type of lights you want to convert to LED

Note

By default JL is equipped in LED diagnostic options and you need to disable it first before activating LED options. LED diagnostics are only checked when you turn on LED options

Enabling auto high beam option on Jeep JL / JT

Note

• this REQUIRES you have the forward facing module up center of the windshield, in the area of the inside rear view mirror. This contains the DASM. It’s the radar and camera that handles ACC, Forward Collision Warning, etc.

This option may not work on early 2019 JL models - software update at the dealer may be required.

If you do not have that black box up there, you cannot enable auto high beams.

Go to Adaptations and open group “Auto Headlamp & Auto High Beam”

• Auto High Beam -> Activated it will activate this option

• Auto High Beam Module Location -> Select IRCM - this tells ecu where the module is installed

• Auto High Beam On Threshold -> 25 km/h - this is default on some cars, on others it is 0 and in booth cases it should work.

• Auto High Beam Off Threshold -> 20 km/h - this is default on some cars, on others it is 0 and in booth cases it should work.

• Auto High Beam CSM Present-> Activated Radio settings screen under “Lights”, adds the menu selection so you can turn it on or off

Jeep JL/JT/4XE front “Off Road” Factory Camera install with CVPM module

• Off Road Capable -> Activated

• Off Road Camera Present -> Activated

Off-Road Pages Activation in Jeep Wrangler JL/JT Using JScan

What You’ll Need: Radio 8.4 other versions don’t have Off-Road pages A compatible OBD2 adapter with CAN-MS access (e.g., vLinker MC+,vLinker MS, OBDLink MX+, ). SGW Bypass module (Security Gateway Bypass) – required for making changes and ensuring proper functionality.

Connect to Your Vehicle

In the JScan app, go to Adaptations or Body Module - Configuration. Look for the Off-Road Pages option

Enable Off-Road Pages

Change the Off-Road Pages setting to Enabled. Save the changes and follow any on-screen instructions.

Restart the Uconnect System (Radio Restart via JScan)

After enabling Off-Road Pages, you must perform two (2x) Uconnect (radio) restarts using the JScan app. This restart function is only available when using an OBD2 adapter with CAN-MS access. Navigate to Adaptations -> Vehicle Maintance in JScan and select !Restart -> find Radio and run restart twice. Full System Reboot (if necessary)

If Off-Road Pages do not appear after the JScan restarts, try disconnecting the battery for a few minutes or performing a hard reset of Uconnect. Verify Activation

Once the system reboots, check if the Off-Road Pages tab appears in the Uconnect menu.

Important Notes:

Jeep Wrangler JL has a built-in Security Gateway (SGW) that blocks unauthorized changes, so you must install an SGW Bypass module before making any modifications. The SGW Bypass must remain installed for Off-Road Pages to function correctly after activation. The JScan radio restart feature is only available with an OBD2 adapter that supports CAN-MS. Without CAN-MS access, you will need to manually restart Uconnect (by disconnecting the battery). Some Uconnect versions may require additional coding or software updates. Ensure you have the latest version of JScan and a compatible OBD2 adapter. If Off-Road Pages do not appear, try re-saving the settings and performing another radio/system restart. Now you’re all set to enjoy the Off-Road Pages feature in your Jeep Wrangler JL! 🚙💨

Jeep JL LED Tail Lamp settings JScan - this is general guide, it may be slightly different for your car

Basically there are 2 types of aftermarket LED lights

1. with resistor – those type of lamps will act like standard bulb lamps

2. without resistor – those type of lamps will act like factory led but without diagnostic

All changes should be done in: Body -> Configuration

1) With resistor LED Rear Turn Lamps Present -> “Not Set” LED Reverse Lamps Present -> “Not Set” LED Stop Lamps Present -> “Not Set” LED Tail Lamps Present -> “Not Set” Left Rear Turn Lamp Diagnostic Present -> “Not Set” Right Rear Turn Lamp Diagnostic Present -> “Not Set”

2) Without resistor: LED Rear Turn Lamps Present -> “Set” LED Reverse Lamps Present -> “Set” LED Stop Lamps Present -> “Set” LED Tail Lamps Present -> “Set” Left Rear Turn Lamp Diagnostic Present -> “Not Set” Right Rear Turn Lamp Diagnostic Present -> “Not Set”

When you are don with settings go to Body Module and clear all trouble codes (DTC). Then lock the car and wait for power cycle (instrument cluster goes to sleep) sometimes it may be required 2x Then you can start testing, it’s important to test with engine started. You can leave OBD adapter connected all the time. All lights are managed from Body module so all codes related to instrument cluster messages are visible there

Gladiator JT (2018+)

General hints for JT

For ESS (and other features) please see the JL section above - JT shares a lot with the JL model.

   • from the drop-down menu choose Tire Pressure Monitor - Power On Restart

   • tap GO

   • once procedure is complete, repeat step 5.

Grand Cherokee (WK/WK2)

Choosing the correct adapter

For WK2 2014+ an MS-CAN capable OBD adapter is required for full compatibility. See Choosing the right adapter in JL/JT section.

Tire Size

Note

In models equipped with the advanced Park Sense module (not the basic, 4-sensor one) setting a bigger tire size will cause Park Sense and ABS errors and there is currently no known solution.

Generally, follow the default Tire Size procedure, and then:

• if everything works fine after you restart the car, you’re good to go

• if you are getting an ABS error:

  • Run ABS Initialization adaptation

  • Run Advanced Scan and clear the error codes

  • Cycle the ignition (shut the car down, wait a moment, start it again)

SRT Mode vs Performance Pages

If you want to enable SRT / Performance Pages on the radio, don’t use SRT Mode Adaptation. This adaptation is used if you actually have an SRT hardware. To enable SRT options on the radio use Performance Pages adaptation, and be aware that the radio might need up to 24 hrs to catch up on changes made and/or a hard reset (pulling the radio fuse) if 24 hrs wait is not enough.

How to: Convert rear lamps on Grand Cherokee < 2014 from US to EU spec

Note

This description is based on Wrangler JK process and might not be accurate. Inspect your vehicle wiring, diagrams and consult with someone who has some experience already. If the description is inaccurate, please reach out to us. Your feedback is highly appreciated.

• Replace US rear lights with EU version

• Set Combined Rear Lightning On/Off -> Set this option to Deactivated. This will leave only turn signals instead of combined lamps.

• You will now need to add a wire from the third (center) stop light to the stop lights on the sides.

How to: Convert rear lamps on Grand Cherokee 2014-2020 from US to EU spec

General steps required to convert car to euro spec

Steps required to enable rear turn signals

• Combined Rear Lightning On/Off -> Set this option to Deactivated – this option will disable, brake with turn, only brake light will be available.

• Check if Rear Turn Lamps Output Present -> Activated – this option will enable large pins C5/E pin number 3 & C6/F pin number 42 on BCM (Body Computer).

  Note

  In most vehicles the wiring harness will already have those pins properly wired. If the conversion doesn’t work as expected, check the wiring first.

• Right – Second Reverse Lamp – On/Off -> Set this option to Deactivated

• Left – Second Reverse Lamp – On/Off -> Set this option to Deactivated

• Replace white reverse bulbs with orange bulbs and conversion is completed

BCM diagram:

Plug / connector layouts:

Steps required to enable rear fog lights

1. Rear Fog Lamps Output Present -> Activated – This option will activate two new pins on BCM C5/E pin number 39 & C6/F pin number 5:

Small pins “KOSTAL 1,2 MLK”

2. Right – Rear Fog Lamp or High Beam Shutter On/Off -> Set to Activated

3. Left – Rear Fog Lamp or High Beam Shutter On/Off -> Set to Activated

4. Add wires to BCM C5/E pin number 39 & C6/F pin number 5

5. Connect wires to new rear fog lights

6. Fog lamp button should now work with double press

Air Suspension - Calibration

Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack. The tires are to be inflated to the recommended pressure. All tires are to be the same size as standard equipment. Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.

HEIGHT MEASUREMENT - all values need to be measuered and enterd in milimiters “mm”

Front:

Front Wheel Center Height – Measure the vertical distance between the front wheel center (1) and the ground (4), Record the measurement. 2. Front Cradle Height – Measure the vertical distance between the center of the cradle bolt (2) to the ground (3), Record the measurement. 3. Take the two measurements and subtract them to get the ride height.

Rear:

Rear Wheel Center Height – Measure the vertical distance between the wheel center (2) and the ground (3), Record the measurement. 5. Rear Cradle Height – Measure the vertical distance between the center of the cradle bolt (1) to the ground (4), Record the measurement. 6. Take the two measurements and subtract them to get the ride height.

Reference Table:

Air Suspension (to be completed)

Key notes:

DO NOT use the Leveling procedure instead of the terrain selector, as it puts the suspension in service mode.

Anything below 50mm for the rear will make the pump keep running forever.

Factory: WK2 - Trailhawk 2020

• Front Left = 90mm

• Front Right = 89mm

• Rear Left = 65mm

• Rear Right - 67mm

Lowered: WK2

• Front Left = 75mm

• Front Right = 74mm

• Rear Left = 50mm

• Rear Right - 52mm

The adjustment of the ride height can change the Normal Ride Height (NRH). The values of different modes (example below) cannot be changed.

For example, for 2011 the basics of how the different automatic settings effect the systems are listed below:

• Auto - When in 4WD High range the vehicle height is at NRH. The vehicle systems are set to normal performance settings. Combines optimal traction with seamless steering feel. When in 4WD Low range the vehicle height adjusts to 38 mm (1.49 in.) above NRH, the transfer case locks, and the transmission shifting adjusts to off road shifting.

• Sport - When in 4WD High range the vehicle height adjusts to 15 mm (0.59 in.) below NRH. Electronic Stability Control (ESC) and traction control tuning thresholds are raised, and the Antilock Brake Control (ABS) allows less wheel slip, all to allow more driver control. Also the transmission shifting adjusts to a higher performance shifting. Not available in 4WD Low range .

• Snow - When in 4WD High range the vehicle height is at NRH. Traction control is adjusted to allow less wheel slip, and initial vehicle launch will be in second gear. When in 4WD Low range the vehicle height adjusts to 33 mm (1.3 in.) above NRH, the transfer case locks, the transmission shifting and ABS adjusts to off road settings.

• Sand/Mud - When in 4WD High range the vehicle height adjusts to 38 mm (1.49 in.) above NRH. Electronic Stability Control (ESC) tuning threshold is raised, and the ABS allows less wheel slip to allow more driver control. When in 4WD Low range the vehicle height adjusts to 38 mm (1.49 in.) above NRH. The transfer case and the Electronic Limited Slip Differential (ELSD) locks, the transmission shifting and ABS adjusts to off road settings.

• Rock - Not available in 4WD High range . When in 4WD Low range the vehicle height adjusts to 65 mm (2.6 in.) above NRH. The transfer case and the ELSD locks, the transmission shifting and ABS adjusts to off road settings, and hill descent control is activated for steep downhill control.

Air suspension delete

Note

For pre-lift (up to 2014) models:

If you’re removing the air suspnesion and replacing it with regular coilovers, follow the steps below (as always: it is YOUR responsibility and we take no liability for any damages)

1. Eemove the 2 fuses related to the air suspension and also the relay located in the relay box beside de fuse panel

2. Disable the air suspension module control with Jscan.

   • Adaptation > Modules Configuration > ASCM - Air Suspension Control On/Off > set to Deactivated

3. Unhook the module itself located under the driver seat.

4. Disconnect the negative terminal of the main battery for 30 seconds and reconnect it to get rid of the message and the blinking buttons.

21. Try to start car.

Gear ratio

The 4xe will not work with axle ratios higher than 4.50. There is no currently known workaround to this limit.

Renegade / Compass / Cherokee

Quick info

Renegade, Compass, and Cherokee are supported, but you need to know the following:

1. They are Fiats with a Jeep badge, and have a completely different software and different customisation options

2. You need to perform PROXI alignment after making changes (research it online please), which:

3. requires vLinker MC+, FD as it’s the only reliable OBD adapter that can perform PROXI, and even then in certain cases a special blue OBD cable might be required

4. If you acknowleddge the above, you can go to JScan settings > app & adapter settings > and enable ‘show experimental vehicles’.

And we highly encourage you to do it first, and explore the vehicle options in Demo mode (especially see PROXI and it’s description) before investing in a license and adapter.

In addition, as with all other 2018+ vehicles from Stellantis, you will need a Security Gateway Bypass cable.

Introduction

After Jeep has become part of FCA / Stellantis, three new models have been launched in cooperation with Fiat. Jeep Renegade, Compass, and Cherokee are technically much closer to the Fiat rather than the Jeep and share the software with the Fiat family. Because of this, applying changes to them is far more complex and requires:

• OBD Link MX+ adapter

AND/OR

• any compatible adapter

• grey OBD adapter cable

• blue OBD adapter cable

These cables allow the OBD adapter to access additional networks, which are used by the vehicles’ modules.

Because of the above, please launch the app in the Demo mode, choose your vehicle and check the PROXI Alignment section to see which cables are required for each alignment.

PROXI Alignment

After you make the desired changes (adaptations), the vehicle configuration must be uploaded to all controlling modules. This is called PROXI alignment, and is done as follows:

• go to PROXI alignment adaptation

• execute all PROXI alignments for modules that DO NOT require a coloured cable

• don’t worry when the information is not updated correctly immediately - this is normal

• unplug the adapter and plug it back in with the grey cable

• perform PROXI adaptations on modules that require the gray cable

• unplug the adapter and plug it back in with the blue cable

• perform PROXI adaptations on modules that require the blue cable

• disconnect

• cycle the ignition

• reconnect

• open PROXI alignment adaptation: all modules should be good to go

This procedure must be performed before driving the car, so you can make more than one adaptation before doing the PROXI alignment. In other words, there is no need to do the PROXI alignment after every single adaptation, but you must do it when you want the car to be fully operational again.
