Fault-Tracing Information

Fault-tracing

Checking the wiring and terminals








- Ignition off, wait for 15 seconds.
- Disconnect the connector from the front passenger airbag switch.
- Disconnect the connector for Supplemental restraint system module (SRS).
Check connectors for damage to pins and connections.
Check the connectors. Check for loose connections. Check for contact resistance. Check for oxidation.
Also check the other connectors and terminals that join the cables between the supplemental restraint system module (SRS) and the switch.
Check the wiring in the circuit for short-circuits to other cables in the circuit. The resistance reading should read infinite resistance.
Take readings between:
- Supplemental restraint system module (SRS) terminal #C2:34(#A34) and #C2:35(#A35).
Remedy as necessary.
