Pinpoint Test 6: The Occupant Classification Sensor Module Does Not Respond to the Scan Tool

PINPOINT TEST 6: THE OCCUPANT CLASSIFICATION SENSOR MODULE DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The occupant classification sensor module communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits (W/L) (HS-CAN +) and (W) (HS-CAN -) provide the HS-CAN network connection to the occupant classification sensor module. The occupant classification sensor module shares the HS-CAN network with the PCM, the ABS module, the four wheel drive (4WD) control module, the instrument cluster, the power steering control module and the restraints control module (RCM). Voltage for the occupant classification sensor module is provided by circuit (W/L) and circuit (B/W) provides ground.

Possible Causes
- Fuse
- Wiring, terminals or connectors
- Occupant classification sensor module

Diagnostic Procedure

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
