W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness 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 Vehicle Repair" procedure
NO
1) Go to "W/Harness Inspection" procedure

Signal Circuit Inspection

Check for short in harness
1. Ignition "OFF"
2. Disconnect driver Door lock actuator.
3. Measure resistance between terminal "9" of DDM and chassis ground
A. Specification : Approx. Infinity Ohms




4. Is the measured resistance within specifications?
YES
1) Go to "Power circuit Inspection" procedure.
NO
1) Check for short in signal harness. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

1. Ignition "OFF"
2. Disconnect driver Door lock actuator.
3. Measure resistance between terminal "4" of DDM and chassis ground
A. Specification : Approx. Infinity Ohms




4. Is the measured resistance within specifications?
YES
1) Go to "Component Inspection" procedure.
NO
1) Check for short in power harness. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
