Grand Cherokee 2WD V8-5.2L VIN Y (1998)
ABS Light: Description and Operation
ABS WARNING LAMP
The amber ABS warning lamp 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. The lamp illuminates at start-up to perform a self check. The lamp goes out when the self check program determines the system is
operating normally. If an ABS component exhibits a fault, the CAB will illuminate the lamp and register a trouble code in the microprocessor. The
lamp is controlled indirectly by the CAB. The instrument cluster inverts the lamp signal. The CAB grounds the circuit to turn off the lamp.
BRAKE WARNING LAMP
The red brake warning lamp 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.
