ABS Indicator Inoperative

Circuit Description
The electronic brake control module (EBCM) turns ON the antilock brake system (ABS) indicator by opening the ABS indicator control circuit. The ABS indicator is connected to the GAUGE fuse. This circuit has power when the ignition switch is in the ON or START positions. When the ignition switch is turned to the ON position, the EBCM turns ON the ABS indicator for 3 seconds for a bulb check. If the EBCM detects a malfunction, the ABS indicator will stay ON to warn the driver that the ABS is disabled and needs service.

Diagnostic Aids
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.
The following are possible causes of the malfunction:
^ An open in the ABS Indicator Control circuit.
^ An internal EBCM malfunction.
^ A malfunctioning Instrument Cluster Panel Assembly.
If an intermittent malfunction exists, refer to Testing for Intermittent and Poor Connections.

Test Description
