^ If the ABS Warning Light -K47- (item no. 1) does not go out after the ignition is switched on and the test sequence is complete, it could be caused by the errors:

-a- voltage supply is under 10 volts.

-b- there is a malfunction in the hydraulic control module; ABS system is therefore not operating.

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

-c- there was a periodic wheel speed sensor malfunction since the last vehicle start.

-d- there is an open circuit in the connection from ABS Warning Light -K47 to ABS control module (w/EDL) -J104-.

-e- ABS Warning Light -K47- is malfunctioning

^ If the ABS Warning Light -K47- (item no. 1) goes out, but the brake and parking brake warning light -K7- (item no. 2) remains lit, the malfunction causes could include:

-a- parking brake is engaged.

-b- brake fluid level is too low.

-c- there is a malfunction in the activation of the brake and parking brake warning light -K7-.





^ If the ABS Warning Light -K47- (item no. 1) and the brake and parking brake warning light -K7- (item no. 2) light up, the ABS system is malfunctioning. Account for differences in braking behavior.
