Level Control System Indicator Lamps, From 09.10

Level Control System Indicator Lamps, From 09.10











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, but the brake system remains fully operational.

- c - There was a malfunction in the speed sensor 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 - Connection from instrument cluster to ABS Control Module (J104) has an open circuit.

- 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) - 3 - and Brake System Indicator Lamp (K118) - 1 -






• If ABS indicator lamp - 3 - goes out but brake system indicator lamp - 1 - lights up, the malfunctions 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 - there is a fault in the wiring to the brake system indicator lamp - 1 -.

• If the brake system indicator lamp - 1 - does not light up during the self-test, check the instrument cluster using Vehicle Diagnostic, Testing and Information System (VAS 5051).

• If the ABS indicator lamp - 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.

ESC Indicator Lamp - 2 -






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

Fault, that affects the ASR/ESP The ABS/EDL and EBD safety systems are still completely functional. Check DTC memory using Vehicle Diagnostic, Testing and Information System (VAS 5051).

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

- b - A fault in the actuation of ESC indicator lamp - 2 -.

- c - The ASR/ESP button (E256) has switched off the ASR/ESP system.

If the ESC Indicator Lamp - 2 - blinks while driving, the ASR or ESP systems are controlling the system.

• 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).

ESC Indicator Lamp Off - 4 -






• If the ESC indicator lamp Off - 4 - 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 Vehicle Diagnostic, Testing and Information System (VAS 5051).

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

- b - A fault occurred when Indicator lamp for ESC Off activated.

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

- d - A fault occurred during activation. Refer to and Vehicle Diagnostic, Testing and Information System (VAS 5051).

• If the ESC indicator lamp - 4 - does not light up during the self-test, check the instrument cluster using Vehicle Diagnostic, Testing and Information System (VAS 5051).
