Normal Operation
The HS-CAN uses an unshielded twisted pair cable, circuits 1827 (WH/LG) and 1828 (PK/LG). The powertrain control module (PCM), the anti-lock brake system (ABS) module and the instrument cluster all communicate with the scan tool using the HS-CAN.

Possible Causes
- Circuit 1827 (WH/LG) open, short to ground or voltage (HS-CAN +)
- Circuit 1828 (PK/LG) open, short to ground or voltage (HS-CAN -)
- Circuit 1827 (WH/LG) (HS-CAN +) and circuit 1828 (PK/LG) (HS-CAN -) shorted together
- ABS module
- Instrument cluster
- PCM
