Traction Off Indicator Always On

Circuit Description
The TRAC OFF indicator is controlled by the EBTCM. The EBCM supplies the ground to CKT 1572 to turn the indicator on. When CKT 1572 is not grounded at the EBCM, the TRAC OFF indicator remains off. When the EBCM sees the traction control switch voltage go low, it turns the TRAC OFF indicator on and disables traction control.

Diagnostic Aids
It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.

^ Thoroughly inspect any circuitry that may be causing the complaint for the following conditions:
- Backed out terminals
- Improper mating
- Broken locks
- Improperly formed or damaged terminals
- Poor terminal-to-wiring connections
- Physical damage to the wiring harness

^ The following conditions may cause an intermittent malfunction:
- A poor connection
- Rubbed-through wire insulation
- A broken wire inside the insulation

^ If an intermittent malfunction exists refer to General Electrical Diagnosis Procedures in Diagrams/Diagnostic Aids for further diagnosis.
