If the ABS warning light -K47- -1- does
not go out after switching ignition on and
completion of test sequence then the
malfunction may be:
-a- Voltage supply is below 10 Volt
-b- There is a malfunction in the ABS
The anti-locking brake system remains
switched off with an ABS malfunction -b-,
but the brake system remains fully
operational.
-c- Since the last time the vehicle was
started there was a temporary speed

In the case of a sensor malfunction -c-,
the ABS warning light -K47- will
extinguish after restarting the engine and
attaining a speed of above 20 km/h
(approx. 13 mph).
-d- The connection from instrument
cluster to ABS Control Module (w/EDL) -
J104- is interrupted (open circuit).
-e- Instrument cluster is faulty.
