DTC C0286 or C086 (Export)





Circuit Description
The EBCM illuminates the ABS indicator by supplying ground to the lamp. When the ABS indicator is commanded ON, the feedback voltage to the EBCM from the ABS indicator failure control circuit is low. The ABS indicator also illuminates if the ground circuit between EBCM and the electronic brake control lamp relay is open.

Conditions for Running the DTC
The ignition is ON.

Conditions for Setting the DTC
The EBCM detects high feedback voltage from the ABS indicator failure control circuit when the ABS indicator is commanded ON.

Action Taken When the DTC Sets
This information-only DTC is stored in EBCM memory until it is cleared by using the specified procedure.

Conditions for Clearing the DTC
The conditions for setting the DTC are no longer present and you use the scan tool Clear DTCs function.

Diagnostic Aids
Thoroughly inspect connections or circuitry that may cause an intermittent malfunction.

Test Description
The number below refers to the step number on the diagnostic table.
5. Damage may occur to the EBCM, the ABS indicator failure control circuit and the ABS indicator lamp relay if the ABS indicator failure control circuit is shorted to voltage.
