Test F: The Occupant Classification Sensor Module Does Not Respond To The Scan Tool
PINPOINT TEST F: 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
VDB04 (WH/BU) (HS-CAN +) and VDB05 (WH) (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). For Hybrid vehicles, the instrument
cluster also shares the HS-CAN network with the transmission control module (TCM) and TBCM. Voltage for the occupant classification sensor
module is provided by circuit CBP46 (WH/BU) and circuit GD183 (BK/WH) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Occupant classification sensor module
