GTI L4-2.0L Turbo (CCTA) (2009)
Tire Monitoring System: Service and Repair
Reset Procedure, Tire Pressure Monitoring System (TPMS) [Alternate Porcedure]
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 (no message in New Beetle and low line clusters).
-
No signals are sent when the car is stationary, unless a rapid pressure loss occurs.
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 an accurate and reliable pressure gage.
-
Tires must be filled when cold.
-
Pressure displayed on the scan tool is delayed for up to 2 minutes while filling is completed.
Adaptation
After replacing a sensor, the TPMS system must be re-learned by performing the following:
Vehicle must be parked for a minimum of 20 minutes (with ignition switched ON for SW391, and Midtronics InCharge 940 (INC 940) battery
charger/maintainer connected), 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.
