ABS Indicator Always On

ABS Indicator Always On





Circuit Description
The ABS indicator is controlled by the EBCM. The EBCM supplies the ground to ABS indicator control circuit in order to keep the indicator off, When ABS indicator control circuit looses ground at the EBCM, the ABS indicator turns on.

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 for further diagnosis.
