^ 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-.

ABS Warning Light -K47- and brake and parking brake warning light -K7
^ 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- brake fluid level is too low
-b- parking brake is engaged.
-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.
WARNING! When the ABS Warning Light -K47- and the brake and parking brake warning light -K7- are lit, the rear wheels can lock early during braking.
