ABS, Brake and ASR/ESP Warning Lamp Malfunction Displays

ABS, Brake and ASR/ESP Warning Lamp Malfunction Displays, from MY 2006





I - Warning Lamps

II - Warning Lamps





Note:
^ ASR/ESP control lamp K155 is used by ABS/EDL/ASR and ABS/EDL/ASR/ESP brake systems.
^ For vehicles without ABS/ASR or ASR/ESP ASR/ESP control lamp K155 is not installed.

Brake Pad Wear Indicator Lamp K32





^ If the brake pad wear indicator lamp K32 - 1 - does not go out after the ignition is switched on and the test sequence is complete, or it lights up while driving, it could be caused by the following errors:

a - Brake pads may be worn.

Check front and rear brake pads.

- b - there is a malfunction in the activation of the brake pad wear indicator lamp K32 for brake pad.

In vehicles with display in instrument cluster, the information text appears:

"CHECK BRAKE PAD"





ABS Warning Lamp K47
^ If the ABS warning lamp K47 - 1 - does not go out after the ignition is switched on and the test sequence is complete, malfunction causes could be:

a - Voltage supply is under 10 volts.

b - There is an ABS malfunction.

The ABS system remains switched off during an ABS malfunction, but the traditional brake system remains fully functional.

c - There was a sensor malfunction since the last vehicle start (sporadic).

In case of a sensor malfunction, the ABS warning lamp will go out automatically after vehicle is started again and a speed of 20 km/h has been exceeded.

d - The connection between instrument cluster and ABS control module J104 is interrupted.

e - The instrument cluster is malfunctioning





ABS Warning Lamp K47 and Brake System Warning Lamp K118
^ If ABS warning lamp K47 - 1 - goes out but brake system warning lamp K18 - 2 - stays on while parking brake is released and 3 warning tones are heard, malfunction causes could be:

a - The brake fluid level is too low.

b - There is a malfunction in the activation of the brake system warning lamp K118.

^ If ABS warning lamp K47 - 1 - and brake system warning lamp K18 - 2 - are on, ABS is malfunctioning and Electronic Brake Distribution (EBD) has ceased functioning.
^ If ABS warning lamp K47 - 1 - and brake system warning lamp K18 - 2 - only light up after 10 km/h or 2000 RPM are reached and 3 warning tones are heard, ABS and EBD have ceased functioning.

CAUTION: After the ABS warning lamp K47 and brake system warning lamp K118 have lighted up, rear wheels may lock early during braking.





ASR/ESP Control Lamp K155
^ If ASR/ESP control lamp K18 - 2 - does not go out after ignition is switched on and the test sequence is complete, malfunction causes could be:

There is a malfunction that only affects the ASR/ESP system. The ABS/EDL and EBD safety systems are still completely functional.

a - Short circuit to B+ in ASR/ESP button E256

b - There is a short circuit to ground (GND) for activation of the ASR/ESP warning lamp.

c - The connection between instrument cluster and ABS control module J104 is interrupted.

d - ASR/ESP was switched off by ASR/ESP button E256

If the ASR/ESP control lamp K155 lights up for 100 milliseconds after ignition is switched on, a code has been entered that does not include ASR/ESP regulation.

Coding ABS control module J104 :

If the ASR/ESP control lamp K155 blinks while driving, the ASR or ESP system is in regulating mode.





ABS Warning Lamp K47, Brake System Warning Lamp K118 and ASR/ESP Control Lamp K155
^ If ABS warning lamp K47 - 1 - and brake system warning lamp K18 - 2 - blink, whereas ASR/ESP control lamp K18 - 2 - remains lit, the control module has not been coded or the coding is 00000.

Coding ABS control module J104 :
