Indirect Tire Pressure Monitoring System






Indirect Tire Pressure Monitoring System

General Information

The tire pressure monitoring system (TPMS) is a software component in the Anti-lock Brake System (ABS) control module. The system will recognize a slow and gradual decrease in tire pressure on a wheel. Diagnostic Trouble Code (DTC) entries for tire pressure monitoring are stored in the ABS control module. With the help of the ABS sensors, the TPMS compares the speed and rolling circumference of the individuals wheels.

After the following repair work and/or changes, and with the ignition switched ON, the tire pressure monitoring display button must be pressed until the confirmation chime sounds:

Tire pressure change

A change in one or more tire

Changing a tire, for example, from the front to rear

If the rolling circumference of a wheel changes, the tire pressure monitoring display indicator lamp lights up in instrument cluster. Wheel circumference of a wheel changes because:

Insufficient tire pressure

Structural damage on tires

Load on vehicle on one side

One axle is loaded heavily, for example when pulling a trailer

Snow chains are used

When spare wheel is installed

One wheel is replaced

Malfunction in the ABS System

If the Anti-Slip Regulation (ASR)/Electronic Stabilization Program (ESP) control lamp or the traction control indicator lamp indicate a malfunction in the ABS system, then the tire pressure monitoring display indicator lamp- arrow - will also illuminate. A malfunction in the TPMS will not be stored in the system.





Warning lamp cannot be turned off by pressing the tire pressure monitoring display button. In this case, perform the following:

- Connect the vehicle diagnosis, testing and information system (VAS 5051) and select "Guided Fault Finding ".
