Low Traction Indicator Inoperative

Low Traction Indicator Inoperative





Circuit Description
The electronic brake control module (EBCM) turns ON the Low Trac indicator by grounding the EBCM Low Trac indicator control circuit. When the EBCM detects that the traction control system is activated, the Low Trac indicator will illuminate.

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 or high resistance in the Low Trac indicator control circuit
^ An open, high resistance or short to ground in the instrument panel cluster (IPC) ignition voltage circuit
^ An open or high resistance in the EBCM ground circuits
^ An internal EBCM malfunction
^ An internal IPC malfunction

If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
5. This step tests the EBCM Low Trac warning lamp circuit for an open or high resistance.
6. This step tests the IPC ignition voltage circuit for an open, high resistance or short to ground.
7. This step tests the EBCM ground circuits.
