Basic setting of tire pressure monitoring


Tire pressure monitoring is a software module in the ABS/ESP-module for finding slow losses of air pressure. The rpm signal from the ABS-system's wheel sensors is used to separately monitor the rolling circumference for each wheel. When the rolling circumference for a wheel changes, a control light turns on in the combi instrument.

Tires' rolling circumference may change when:

The system for tire pressure monitoring has a yellow control light in the combi instrument that indicates as follows:

There are different versions of tire pressure monitoring, current instruction applies for PR-number: 7K1, 7K6, and 7K9.

The car's PR-number can be read on the vehicle data plate, usually located in the spare wheel well or on the first page in the service book.

Test conditions:

Procedure:

"FIRST BASIC SETTING" (with flashing control light):

  1. Check tire pressure and adjust as needed.

  2. At the same time, press the ASR/ESP button and the button for tire pressure monitoring (SET) for at least 2 seconds. An acknowledgement tone is heard after successful calibration.

  3. The function is done.

"BASIC SETTING" (with fixed control light and warning sound):

  1. Check tire pressure and adjust as needed.

  2. Press the button for tire pressure monitoring (SET) for at least 2 seconds. An acknowledgement tone is heard after successful calibration.

  3. The function is done.
