ABS Light: Description and Operation

An amber "ANTILOCK" indicator lamp, located in the instrument panel cluster, operates as follows under normal conditions:
- When ignition switch is turned to "RUN" prior to starting the engine, the "ANTILOCK" lamp comes on for a short period of time, and then goes out.
- As engine is cranked, the red "BRAKE" and amber "ANTILOCK" lamps come on. When the key is returned to the "RUN" position, both lamps will go off. Neither the red "BRAKE" warning lamp or the amber "ANTILOCK" indicator lamp should come on while the vehicle is being driven.
- The "ANTILOCK" lamp will come on also when a malfunction in the ABS is detected by the control module. If only this lamp is on, normal braking is available. However, if both the red "BRAKE" and amber "ANTILOCK" lamps are on during vehicle operation, something might be wrong with the hydraulic brake system.
