TPMS - Tire Pressure Monitor System
There are two types of the TPMS: Standard and Premium. They both monitor tire pressure, but the premium version is capable of displaying more details, like current pressure on the EVIC (the electronic display in the instrument cluster). The basic TPMS version was installed up to around 2011 in Wrangler JK, and most other vehicles past 2012 have the premium variant.
Note
TPMS is slow to respond to changes. It has it’s own cache and can remember multiple settings. Either be patient, or reset the TPMS after applying changes - see details below.
Disabling TPMS
That’s the most basic change. If you want to disable the system completely it is advisable (though not necessary) that you have a proper tire pressure before you begin, i.e. no warning is up.
Connect to your vehicle
Open Adaptation
Open TPMS settings
Set the following, if present (these options’ naming varies from vehicle to vehicle):
TPMS On/Off: deactivated
TPMS Premium On/Off: deactivated
Base TPMS system present On/Off: deactivated
TPMS System present On/Off: deactivated
Premium TPMS System present On/Off: deactivated
Don’t worry if deactivating some of these does not work. This only means that the setting is present in the vehicle software, but this particular model doesn’t use it.
Reset the TPMS:
Close the car, let it sit for a few minutes. If you see no change in behaviour, continue to the next step:
On most vehicles disconnecting the battery for a few minutes resets the TPMS, hower some newer vehicles have others systems relying on a constant power supply, so instead you can use !Restart all ecus option (usually available in Miscellaneous Settings section).
On RAM Trucks run the RFH Replace procedure found under Adaptations > Radio Frequency Hub
Changing TPMS thresholds
This is a simple change, and again - it is highly advisable to not have any TPMS warnings active.
Connect to your vehicle
Open Adaptation
Open TPMS settings
Set TPMS thresholds in the applicable setting(s) from the following list:
TPMS Threshold: for vehicles equipped with the basic version
TPMS Threshold - EVIC version: well… yes, for vehicles with the premium version
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 when the vehicle is fully loaded. Change this value first and see if it does the job.
Reset the TPMS:
Close the car, let it sit for a few minutes. If you see no change in behaviour, continue to the next step:
On most vehicles disconnecting the battery for a few minutes resets the TPMS, however:
some newer vehicles have others systems relying on a constant power supply, so instead you can use !Restart all ecus option (usually available in Miscellaneous Settings section).
