C0110 ? 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 Testing for Intermittent Conditions and Poor Connections .

1. Disconnect the electronic brake control module (EBCM) harness connector.
2. Connect the J 39700 Universal Pinout Box using the J 39700-530 Cable Adapter to the EBCM harness connector only.
3. Test both ground circuits of the EBCM including the EBCM ground for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs.
4. Test the Battery Positive Voltage circuits for an open, high resistance, or a short to ground. Refer to Circuit Testing and Wiring Repairs.
