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 network connection to the instrument cluster. The instrument cluster shares the HS-CAN with the powertrain control module (PCM), the restraints control module (RCM), the occupant classification sensor module, the four wheel drive (4WD) control module, and the smart junction box (SJB). Voltage is supplied by circuits SBP33 (RD), CBP09 (VT/GY) and CBP10 (YE/OG). Ground is supplied by circuits GD161 (BK/YE) and GD174 (BK/WH).

DTC U0002 (Instrument Cluster) - sets when there is a communication problem on the HS-CAN bus.

Possible Causes
- Fuse
- Circuit VDB04 (WH/BU) open (HS-CAN +)
- Circuit VDB05 (WH) open (HS-CAN -)
- Circuit SBP33 (RD) open
- Circuit CBP09 (VT/GY) open
- Circuit CBP10 (YE/OG) open
- Circuit GD161 (BK/YE) open
- Circuit GD174 (BK/WH) open
