Normal Indicator Operation

The Antilock Brake System (ABS) uses three indicator lamps: the red "BRAKE" warning lamp, an amber "ABS INOP" indicator lamp and an amber "LOW TRAC" indicator lamp, all located in the instrument cluster. Under normal conditions, these lamps should operate as follows:
1. When ignition is turned to "RUN" position, prior to starting engine, amber "ABS INOP" indicator lamp should go on and red "BRAKE" warning lamp should flash.
2. As engine is cranked, red "BRAKE" warning lamp and amber "ABS INOP" indicator lamp should come on and "LOW TRAC" indicator lamp may come on and off.
3. When engine is started, amber "ABS INOP" and red "BRAKE" lamps should go out and "LOW TRAC" indicator lamp may come on and off. The operation of these three indicator lamps is an important part of the Antilock Brake System (ABS) diagnosis. If the warning/indicator lamps turn on while driving the vehicle, this indicates a malfunction. If the warning/indicator lamps do not turn on under normal conditions as described above, service the lamps as soon as possible.
