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?






Main harness Circuit Inspection

1. Ignition "OFF".
2. Disconnect the battery (-) terminal cable from the battery and wait at least one minute.
3. Disconnect Seat-belt Buckle Switch connector and SRSCM main harness connector.
4. Measure resistance between of the Buckle Switch Passenger wiring connector and SRSCM harness connector.

Specification : approx. 1 Ohm below





5. Is the measured resistance within specifications?
