| Brake pad warning lamp -K32- |
| t
| If the brake pad warning lamp -K32--2- does not go out 3 seconds after the ignition is switched on, or it if comes on during vehicle operation, the fault may be: |
| -a- The brake pads are worn. |
| Check brake pads/linings on front and rear axles. Renew worn brake pads/linings. |
| t
| If the ABS warning lamp -K47--3- does not go out after the ignition has been switched on and test sequence has been completed, then the fault may be: |
| -a-: The voltage supply is below 10 volts. |
| -b-: There is a fault in the ABS. |
WARNING | In the event of an ABS fault -b-, the anti-lock brake system remains switched off, but the brake system remains fully operational. |
|
| -c-: A temporary speed sensor fault occurred since the vehicle was last started. |
| In this case, the ABS warning lamp will go out automatically after the engine is restarted and the vehicle exceeds a speed of 20 km/h (approx. 13 mph). |
| -e-: The dash panel insert is defective. |
| ABS warning lamp -K47- and brake system warning lamp -K118- |
| t
| If the ABS warning lamp -K47--3- goes out but the brake system warning lamp -K118--4- remains on, then the fault may be: |
| -a- The handbrake is applied. |
| -b- The brake fluid level is too low (the warning lamp flashes). |
| Three warning tones are audible after ignition is switched on. |
| t
| If the ABS warning lamp -K47--3- and the brake system warning lamp -K118--4- light up, then the anti-lock brake system is defective. A change in braking behaviour is to be reckoned with. |
WARNING | After the ABS warning lamp -K47- and the brake system warning lamp -K118- have lit up, it is possible that the rear wheels will lock up earlier. |
|
| Traction control system warning lamp -K86- |
| t
| If the traction control system warning lamp -K86--1- does not go out after switching ignition on and completion of test sequence then the fault may be: |
| There is a fault present which only affects the TCS. The ABS and EBD safety systems on the vehicle remain fully functional ⇒ Read fault memory. |
| -a-: Short-circuit to positive in TCS button -E256-. |
| -c-: The TSC system was shut off by the TCS button -E256-. |
| If traction control system warning lamp -K86- flashes while the vehicle is in motion, the TCS is in operation. |
| t
| If the TCS warning lamp -K86--1- does not light up during the self-test, the fault may be: |
| -a-: The TCS warning lamp -K86- is defective. ⇒ Performing electrical check. |
| ESP and TCS warning lamp -K155- |
| t
| If the ESP and TCS warning lamp -K155--1- does not go out after the ignition has been switched on and the test sequence has been completed, then the fault may be: |
| A fault in the system affecting only the TCS/ESP. The ABS/EDL and EBD safety systems in the vehicle remain fully functional ⇒ Read fault memory. |
| -a-: Short-circuit to positive in TCS and ESP button -E256-. |
| -c-: The TCS/ESP system was shut off by the TCS and ESP button -E256-. |
| If the ESP and TCS warning lamp -K155- flashes while the vehicle is in motion, the TCS or ESP system is regulating the system. |
| t
| If the ESP and TCS warning lamp -K155--1- does not light up during the self-test, the fault may be: |
| -a-: The ESP and TCS warning lamp -K155- is defective. ⇒ Performing electrical check. |
