ABS Warning Lamp

ABS warning lamp

The ABS or TC/ABS control module monitors the function of the ABS system and turns ON the ABS warning lamp on the right-hand side of the main instrument unit if there is a problem.

When the ABS lamp lights up, the anti-lock braking system is disabled and the brakes work just like a conventional braking system.

( ABS ) Cars With Non Bus System:

Schematic:

On cars with ABS (non-bus system), the ABS control module will ground pin 7 on the main instrument unit, whereby the control module will turn ON the warning lamp.

( ABS ) Cars With Bus System:

Schematic:

On cars with TC/ABS (bus system), the main instrument unit will receive information on the bus to turn ON/OFF the lamp.

The TC/ABS control module turns ON the lamp when the ignition is turned ON and turns it OFF again after about 3 seconds provided there are no faults.

The brake fluid warning lamp and the central warning lamp will also come on when the ABS warning lamp comes ON.
