W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
3. Has a problem been found?
YES
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
1) Go to "Power Supply Circuit Inspection" procedure

Power Supply Circuit Inspection

1. Ignition "ON" & Engine "OFF"
2. Measure voltage between terminal 1 of the CCV harness connector and chassis ground
A. Specification : Approx. B+




3. Is voltage within specification?
YES
1) Go to "Control Circuit Inspection"
NO
1) Check for a open in the power supply circuit. Repair as necessary and go to "Verification of Vehicle Repair" procedure

Control Circuit Inspection

1. Ignition "OFF"
2. Disconnect ECM connector
3. Measure resistance between terminal 2 of the CCV harness connector and 91 of the ECM harness connector
A. Specification : Approx. 0 Ohm




4. Is resistance within specification?
YES
1) Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure
