ABS and Brake Warning Indicators
ABS AND BRAKE WARNING INDICATORThe amber ABS warning indicator is located in the instrument cluster. It is used to inform the driver that the antilock function has been turned off due to a system malfunction. On some systems the warning indicator is controlled directly by the CAB. On an XJ, the CAB controls the indicator indirectly. The ABS light relay provides a ground path for the ABS warning indicator driver. The CAB grounds the ABS light relay control circuit to turn off the indicator.
The red brake warning indicator is located in the instrument cluster. It can be activated by application of the parking brake, a leak in the front or rear wheel brake hydraulic circuit, or by turning the ignition switch to the start position.
