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 "Power Circuit Inspection" procedure
Power Supply Circuit Inspection
Check Power To Range Switch ,
1. Disconnect "TRANSAXLE RANGE SWITCH" connector.
2. Ignition "ON" & Engine "OFF".
3. Measure voltage between terminal"8" of the sensor harness connector and chassis ground.
A. Specification : Approx. B+
4. Is voltage within specifications ?
YES
1) Go to "Signal Circuit Inspection" procedure
NO
1) Check that Fuse 1 - 10 A is installed or not blown.
2) Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure
Signal Circuit Inspection
