W/Harness Inspection

Airbag(Event #1)
B1473 Inflatable Curtain Airbag Front-Driver Resistance too High - Inspection/Repair:_: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 shorting bar/shorting bar release pin and connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?






Squib Circuit Inspection

1. Ignition "OFF".
2. Disconnect (-) terminal cable from battery and wait for 1 minutes or more.
3. Disconnect DCAB module and connect the dummy and dummy adapter to main harness connector.

NOTE:
If dummy and dummy adaptor are not able to be prepared, use a known-good DCAB or 2Ohms resistor.

4. Connect (-) terminal cable to battery and Ignition "ON" & Engine "OFF" and wait for 30 seconds or more.
5. Connect scantool to Data Link Connector(DLC) and clear DTC with scantool and diagnose again.




6. Is DTC present problem ?






Main harness Circuit Inspection

1. Ignition "OFF".
2. Disconnect the battery (-) terminal cable from the battery and wait at least one minutes.
3. Disconnect DCAB connector and SRSCM main harness connector.
4. Measure resistance between terminal "Low" and "High" of the DCAB harness connector.

Specification :approx. 1 Ohms below




5. Is the measured resistance within specifications?
