Checking The Component
- Switch off the ignition. Wait 10 seconds
- Disconnect the 10-pin connector from the occupant weight sensor (OWS)
- Disconnect connector A from the central electronic module (CEM).CAUTION:
Do not touch the terminal pins in the supplemental restraint system module (SRS), the central electronic module (CEM) and the occupant weight sensor (OWS). There is a risk of static discharge which could damage the control modules.
Check the connectors for the central electronic module (CEM) and the occupant weight sensor (OWS). Check for damage to pins and terminals in the connectors. Check for contact resistance.
Also check the other connectors that connect the power supply cable between the central electronic module (CEM) and the occupant weight sensor (OWS).
Remedy as necessary.
Check the power supply cable between the central electronic module (CEM) and the connector for the occupant weight sensor (OWS). Check for an open-circuit. Check the fuse.
Check the cable between:
- Central electronic module (CEM) terminal #A10 and the 10-pin connector for occupant weight sensor (OWS) terminal #2.
Remedy as necessary.
Check the ground connection for the occupant weight sensor (OWS). Check for an open-circuit. Check for contact resistance.
Check the cable between the 10-pin connector for the occupant weight sensor (OWS) terminal #9 and the ground terminal.
Remedy as necessary.
Disconnect the connector from the supplemental restraint system module (SRS). 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 an open-circuit.
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.
Replace the pressure sensor and the occupant weight sensor module (OWS) if no fault is 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.
