ABS Indicator On No DTC Set

CIRCUIT DESCRIPTION
The Electronic Brake Control Module (EBCM) turns ON the ABS warning indicator by grounding terminal 11.

The ABS warning 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 warning indicator for 3 seconds for a bulb check. If the EBCM detects a malfunction the ABS warning indicator will stay ON to warn the driver that the ABS is disabled and needs service.

DIAGNOSTIC AIDS
Inspect for a short to ground between the EBCM and the instrument cluster. Inspect the following harness connectors for improperly formed or damaged terminals or physical damage to the wiring harness before component replacement:
^ The EBCM electrical connector
^ The Instrument panel gauge cluster electrical connector

The ABS indicator will remain ON until the vehicle is road tested after the repair of the following Diagnostic Trouble Codes:
^ C0036
^ C0041
^ C0046
^ C0051
^ C0110
^ C0114
^ C0116

TEST DESCRIPTION
The number(s) below refer to the step number(s) on the diagnostic table.
2. After repairs that set a certain DTCs (refer to Diagnostic Aids for specific DTCs) even after clearing DTCs the ABS will keep the ABS indicator ON until a road test is performed to confirm proper system operation.
3. Determines whether there is a short to ground in the ABS indicator circuit or a malfunctioning EBCM.
4. Refer to Diagnostic Aids for a list of DTCs that need road test confirmation before the ABS indicator is turned OFF.
5. A short to ground in the WHT/RED wire will keep the ABS indicator ON.
