Automatically Learn Wheel Electronics
Automatically Learn Wheel Electronics
If wheels are changed (e.g. change from summer to winter tires), wheel electronics send data as soon as speed of new wheels exceeds 25 km/h. Wheel electronics identification numbers are automatically recognized and read by control module.
An acceleration data check also occurs with vehicle speed. This process takes about 7 minutes.
Tire Pressure Monitoring Control Module (J502) must first be in learning mode before it can automatically learn wheel electronics.
Vehicle must stand for 20 minutes for this. This takes 5 minutes after a recognized tire puncture.
If the standing time is not followed, control module is not in learning mode so system recognizes a malfunction and can only automatically learn wheel electronics after standing 20 minutes.
• When changing wheels, be sure to install only Volkswagen approved wheel/tires combinations with tire pressures listed on the tank flap.
• If unapproved wheel/tire combinations are installed, these must have a TUV certificate for the particular vehicle and a 2nd wheel set must be learned via the Vehicle Diagnosis, Testing and Information System (VAS 5051B).
• Learning is also needed if tire pressure deviates from pressures given on fuel filler flap.
Wheel Sets with Other Specified Tire Pressures
If a vehicle is equipped with tires which have specified pressures different from those listed on fuel filler flap, these tires (2nd wheel set) can also be monitored by the Tire Pressure Monitoring System (TPMS).
Specified values for a 2nd wheel set must be entered in system using (VAS 5051B).
Wheel electronics on wheels from 2nd set are not automatically recognized and learned by the Tire Pressure Monitoring System (as wheel electronics on Volkswagen approved wheel/tire combination set are).
To change to a 2nd wheel set, the following steps must be carried out:
• Read the wheel electronic (tire pressure sensors) identification numbers (IDs) before installing.
• Switch the TPMS to wheel set 2.
• Enter needed specified tire pressures and wheel electronic IDs in system.
