Checking The Component
- Switch off the ignition. Wait 10 seconds
- Disconnect the 10-pin connector from the occupant weight sensor (OWS)
- Disconnect the connector from the supplemental restraint system module (SRS).CAUTION:
Do not touch the terminal pins in the supplemental restraint system module (SRS) and the occupant weight sensor (OWS). There is a risk of static discharge which could damage the control modules.
Check the connectors for the occupant weight sensor (OWS) and the supplemental restraint system module (SRS). Check for damage to pins and terminals in the connectors.
Also check the other connectors that connect the communication cable between the supplemental restraint system module (SRS) and the occupant weight sensor (OWS).
Remedy as necessary.
Check the communication cable (LIN-bus) between the supplemental restraint system module (SRS) and the 10-pin connector for the occupant weight sensor (OWS). Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Check the cable between supplemental restraint system module (SRS) terminal #57 and the 10-pin connector for occupant weight sensor (OWS) terminal #10.
Remedy as necessary.
If no fault is found, replace the supplemental restraint system module (SRS).
Remedy as necessary.
Replace the pressure sensor and the occupant weight sensor module (OWS) if a fault is still not detected. The pressure sensor and occupant weight sensor (OWS) module are included in the occupant weight sensor (OWS) system.
NOTE:After replacing the pressure sensor and the occupant weight sensor (OWS) module in the occupant weight sensor (OWS) system, the supplemental restraint system module (SRS) must be configured. This is done by storing the ID number for the occupant weight sensor (OWS).
The occupant weight sensor (OWS) must also be calibrated.
