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 then go to "Verification of Vehicle Repair" procedure.
NO
1) Go to "Main harness circuit inspection" procedure.

Main harness Circuit Inspection

1. Ignition "OFF".
2. Disconnect the battery (-) terminal cable from the battery, and wait at least One minute.
3. Disconnect junction block I/P-H connector and SRSCM main harness connector.
4. Measure resistance value between terminal "15" of main harness of SRSCM and "9" of harness of I/P-E
A. Specification: 0 Ohm




5. Is the measured resistance within specifications ?
YES
1) Go to "Main harness circuit inspection" procedure.
NO
1) Substitute the SRS main harness and check for proper operation.
If the problem is corrected, replace SRS main harness and then go to "Verification of Vehicle Repair" procedure.

Main harness Circuit Inspection

1. Ignition "OFF".
2. Remove the Instrument cluster from crash pad assembly.
3. Ignition "OFF" & Engine "OFF".
4. Measure resistance between terminal "5" of the instrument cluster harness connector and chassis ground.
A. Specification: Infinity




5. Is the measured resistance within specifications ?
YES
1) Check warning lamp and connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check airbag fuse, junction block, Warning Lamp, harness between junction block and SRSCM. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
