Chart 2:

Normal Operation
The instrument cluster communicates with the scan tool through the high speed controller area network (HS-CAN). Voltage to the instrument cluster is supplied by circuits (R), (V/GY) and (Y/O). Ground is supplied by circuits (B/Y) and (B/W).

Possible Causes
- fuse(s)
- circuit (R) open
- circuit (V/GY) open
- circuit (B/W) open
- circuit (Y/O) open
- circuit (B/Y) open
- Instrument cluster

CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
