Level Control System Indicator Lamps

Level Control System Indicator Lamps











ABS Indicator Lamp (K47)






• If ABS indicator lamp - 3 - does not go out after the ignition is switched on and the test sequence is complete, it could be caused by the following errors:

- a - Voltage supply is under 10 volts.

- b - There is an ABS malfunction. Check using Vehicle Diagnostic, Testing and Information System (VAS 5051).


The anti-locking brake system remains switched off with an ABS malfunction - 3 -, but the brake system remains fully operational.

- c - There was a malfunction since the last time the vehicle was started.

In this case the ABS indicator lamp will go out after the engine is restarted and the vehicle speed exceeds 20 km/h.

- d - There is an open circuit from the instrument cluster to the ABS control module (J104).

- e - The instrument cluster is faulty.

• If the ABS indicator lamp - 3 - does not light up during the self-test, check the instrument cluster using Vehicle Diagnostic, Testing and Information System (VAS 5051).

ABS Indicator Lamp (K47) and Brake System Indicator Lamp (K118)






• If ABS indicator lamp - 3 - goes out but brake system indicator lamp - 1 - lights up, the malfunction causes may be:

- a - parking brake is engaged.

- b - brake fluid level is too low (warning lamp blinks).

Three warning tones will sound after switching on the ignition.

- c - a malfunction in wiring to brake system indicator lamp.

• If the ABS indicator light - 3 - and the brake system indicator lamp - 1 - both light up, the ABS system is faulty. A change in braking behavior should be checked.


After ABS indicator lamp and brake system indicator lamp light up, rear wheels may lock prematurely when braking.

Traction Control Indicator Lamp (K86)






• If the traction control indicator lamp - 2 - does not go out after the ignition is switched on and the test sequence is complete, malfunction causes may be:

ASR malfunction. The ABS still works. Check the DTC memory using the Vehicle Diagnostic, Testing and Information System (VAS 5051).

- a - Short circuit to B+ in ASR/ESP Button (E256).

- b - A malfunction in the actuation of traction control indicator lamp (K86). Refer to and the Vehicle Diagnostic, Testing and Information System (VAS 5051).

- c - The ASR/ESP button (E256) turns off the traction control.

If the traction control indicator lamp blinks while driving, ASR system is operating in regulated mode.

• If the traction control indicator lamp - 2 - does not light up during the self-test, check the instrument cluster using Vehicle Diagnostic, Testing and Information System (VAS 5051).
