Test G: The Instrument Cluster (IC) Does Not Respond To The Scan Tool
PINPOINT TEST G: THE INSTRUMENT CLUSTER (IC) DOES NOT RESPOND TO THE SCAN TOOL
Normal Operation
The instrument cluster (IC) 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 connection to the IC and circuits VDB06 (GY/OG) (MS-CAN +) and VDB07
(VT/OG) (MS-CAN -) provide the MS-CAN connection to the IC. Voltage for the IC is provided by circuits CBP23 (BN/YE), SBP07 (WH/RD) and
CBP20 (YE/VT). Circuit GD116 (BK/VT) provides ground.
The IC shares the HS-CAN with the following modules:
-
ABS module
-
Accessory protocol interface module (APIM) (if equipped)
-
Instrument cluster (IC)
-
Occupant classification system module (OCSM)
-
PCM
-
Restraints control module (RCM)
-
Transmission control module (TCM) (if equipped)
-
4X4 control module (if equipped)
The IC shares the MS-CAN with the following modules:
-
APIM (if equipped)
-
Audio control module (ACM)
-
Audio digital signal processing (DSP) module (if equipped)
-
Driver seat module (DSM) (if equipped)
-
Driver door module (DDM) (if equipped)
-
Dual climate control seat module (DCSM) (if equipped)
-
Heating ventilation air conditioning (HVAC) module (if equipped)
-
Parking aid module (PAM) (if equipped)
-
Satellite digital audio receiver system (SDARS) module (if equipped)
-
Smart junction box (SJB)
