Reset Procedure, Tire Pressure Monitoring System (TPMS)

GENERAL SYSTEM FUNCTION DESCRIPTION
- As the tires spin, signals are sent from the sensors (located in each wheel) to the -R47- antenna. This antenna is connected to the Comfort and Convenience Control Module -J393-. The Tire Pressure Monitoring Control Module -J502- is integrated into -J393-.

- -J502- will determine if pressure in the tire is correct. If it is not correct, a yellow warning lamp will illuminate without sound on the instrument cluster and a message will display in the Multi Function Indicator (MFI).

Tip:
Adding pressure to a tire and driving the car will stop the lamp from illumination and is not covered by warranty.

Changing tires or replacing sensors may create a customer concern, as the system take 20 minutes to go in a learn mode for sensor and control unit (see Diagnosis, Adaptation).

Tire Filling
- Check tire pressure using VAS 5216 or equivalent.
- Tires must be filled when cold.
- Pressure displayed on the scan tool is delayed for approximately 20 seconds while filling is completed.

Tip:
Filling the tire and driving the car will stop the lamp from illuminating and is not covered by warranty.

Adaptation
After replacing a sensor or changing to a spare tire, the TPMS system must be re-learned by performing the following:

Vehicle must be parked for a minimum of 20 minutes before the TPMS system will go into learn mode.

- Start vehicle and drive 25 KM/h (16 mph) for at least 7 minutes.
- TPMS then recognizes sensor inputs.
- Warning light in cluster will go out.
