Fault-tracing

Checking the wiring and terminals








- Ignition off, wait for 15 seconds.
- Disconnect the connector to the occupant weight sensor (OWS).
- 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 connect the communication cables between the supplemental restraint system module (SRS) and the occupant weight sensor (OWS).
Check the power supply and the ground terminal for the occupant weight sensor (OWS).
Check the communication cables between the supplemental restraint system module (SRS) and the occupant weight sensor (OWS).
Check the cable for an open-circuit.
Take readings between:
- Supplemental restraint system module (SRS) terminal #C1:73(#C13) and occupant weight sensor (OWS) terminal #10.
- Supplemental restraint system module (SRS) terminal #C1:72(#C12) and occupant weight sensor (OWS) terminal #1.
Remedy as necessary.
