Chrysler Pacifica

Client story

Since I imported a Chrysler Pacifica, I had issues with the adaptive cruise control. Tried to calibrate it 4 times (2x with JScan, 2x with other tools).

If it didn’t work 4 times, it means the radar is to be replaced, so I bought a new one and installed it immediately. The next day I calibrated it with Jscan without an issue - instant smile on my face

Radar calibration

First and foremost, you need to properly align the radar horizontally and vertically. The best solution is a dedicated tool for that.

Once the radar is levelled:

  1. Put the key in RUN and connect with JScan as usual.

  2. Go to Adaptations, tap the search icon and type “ACC”.

  3. Select “ACC - Sensor Calibration - BETA”.

  4. Follow the instructions and confirm the levelling of the radar.

Note

The app will hint which srew should be adjusted and how much, to set the radar perfectly. The calibration will only succeed if the deviations i below 2%.

  1. After confirming the manual levelling, turn the ignition OFF, and then start the engine (don’t disconnect JScan).

  2. Start the calibration / learning by pressing “GO”.

  3. A progress indicator will appear. All items need an OK status, otherwise the calibration will not begin.

  4. Go on a straight road with typical traffic where you can reach a speed of at least 40 km/h.

  5. The whole calibration cycle may take between 5 and 15 minutes.

  6. Once complete, the progress will show 100%.

  7. Stop the vehicle in a safe place and tap “GO”.

  8. The app will hint to turn the engine off - do it.

The radar is now calibrated, and you can use the Adaptive Cruise Control (refer to your user manual). Of course test teh proper operation of the ACC: activate it, set a distance to preceeding vehicle, and verify that your car actually adjusts the speed to keep the distance.

Rear fog lamps (EU conversion) issue

For hybrid cars activate rear fog lamps the same procedure as for non-hybrid, through corresponding settings.

Unfortunately in the hybrid model, it is not activating the rear fog lamp symbol on the dash. The led is in the dash. To activate it you need to change the country of delivery (Country Code) to EU. But after the change you will lose some functions: front radar, parking sensors and etc..

Re-calibrating the radar should be possible, but it not confirmed.
