-b- There is an ABS malfunction, refer to Vehicle Diagnostic Tester.
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-, refer to the Wiring Diagrams.
-e- the instrument cluster is faulty.
- If the ABS Indicator Lamp -K47- -3- does not light up during the self-test, check the instrument cluster → perform an electrical test, refer to the Vehicle Diagnostic Tester.
