Milan FWD L4-2.3L VIN Z (2007)
F4
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 network connection to the occupant classification sensor module. The
occupant classification sensor module shares the HS-CAN with the powertrain control module (PCM), the transmission control module (TCM), the
anti-lock brake system (ABS) module, the restraints control module (RCM), the 4WD control module (if equipped) and the instrument cluster.
Voltage to the occupant classification sensor module is supplied by circuit CBP24 (VT/GN). Ground is supplied by circuit GD127 (BK/BU).
