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 "Signal Circuit Inspection" procedure

Signal Circuit Inspection

Check for Open In Harness
1. Ignition "OFF"
2. Measure resistance between terminal "11" of IMS and terminal "3" of powerseat slide sensor.
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.
Check for short in harness
1. Ignition "OFF"
2. Disconnect powerseat slide motor.
3. Measure resistance between terminal "11" of IMS and chassis ground
A. Specification : Approx. Infinity Ohms




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