• If traction control indicator lamp - 1 - does not go out after the ignition is switched on and the test sequence is complete, malfunction causes may be:
There is a malfunction present which only affects the ASR. The ABS and EBD safety systems are still completely functional => DTC memory.
- a - Short to positive in ASR/ESP button (E256).
- b - A malfunction in activation of traction control indicator lamp (K86)
- c - ASR system was switched off by ASR/ESP Button (E256)
If traction control indicator lamp blinks while driving, ASR system is operating in regulated mode.

- a - Short circuit to B+ in ASR/ESP button (E256).
- b - A malfunction in the actuation of ASR/ESP indicator lamp.
- c - ASR/ESP system was switched off by ASR/ESP button
If ASR/ESP indicator lamp (K155) flashes while driving, the ASR or ESP systems are regulating the system.
• If the ASR/ESP indicator lamp - 1 - did not light up during self-test, the following malfunction is present:
- a - The ASR/ESP indicator lamp is faulty => perform an electrical test.
