Edge FWD V6-3.5L (2007)
H5-H6
Normal Operation
The instrument cluster 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 instrument cluster and circuits VDB06 (GY/OG)
(MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the MS-CAN network connection to the instrument cluster. The instrument cluster shares
the HS-CAN network with the PCM, the ABS module, the four wheel drive (4WD) control module (if equipped), the restraints control module
(RCM), the occupant classification sensor module, the adaptive front lighting module (if equipped) and the steering angle sensor module (if equipped).
The instrument cluster shares the MS-CAN network with the smart junction box (SJB), the electronic automatic temperature control (EATC) module
(if equipped), the audio unit, the THX(R) amplifier (if equipped), the satellite radio receiver (if equipped), the driver seat module (DSM) (if
equipped), the climate controlled seat module (if equipped), the power liftgate module (if equipped), the parking aid module (if equipped), and the
digital versatile disc (DVD) player (if equipped). Voltage for the instrument cluster is provided by circuits CBP29 (WH/VT) and SBP26 (YE/RD).
Circuit GD115 (BK/GY) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Instrument cluster
Test I: The Smart Junction Box (SJB) Does Not Respond To The Scan Tool
PINPOINT TEST I: THE SMART JUNCTION BOX (SJB) DOES NOT RESPOND TO THE SCAN TOOL
