Normal Operation
The ABS module communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits 1827 (WH/LG) (HS-CAN +) and 1828 (PK/LG) (HS-CAN -) provide the network connection to the ABS module. The ABS module shares the HS-CAN network with the powertrain control module (PCM) and the instrument cluster. Voltage for the ABS module is provided by circuits 601 (LB/PK) and 1844 (LG/RD). Both circuits 1205 (BK) provide ground.

Possible Causes
- Fuse
- Circuit 601 (LB/PK) open
- Circuit 1205 (BK) open
- Circuit 1827 (WH/LG) open (HS-CAN +)
- Circuit 1828 (PK/LG) open (HS-CAN -)
- Circuit 1844 (LG/RD) open
- ABS module
