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

1. Check for open in harness
1. Ignition "ON" & engine "OFF".
2. Measure resistance between terminal "F28-2-7, F27-2-7" of PSD and terminal "D54-1, D44-1" of APS.
A. Specification : Approx. 0 Ohm




3. Is the measured resistance within specifications?
YES
1) Go to "Check for short in harness" procedure.
NO
1) Check for open in signal harness. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
2. Check for short in harness
1. Ignition "ON" & engine "OFF"
2. Measure resistance between terminal "F28-2-7, F27-2-7" and terminal "F28-2-26, F27-2-26 : F28-1-1, F27-1-1)" of PSD.
A. Specification : Approx. Infinity Ohms




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