Normal Operation
The ABS module communicates with the scan tool through the high speed controller area network (HS-CAN), circuits 1847 (WH/OG) and 1848 (PK/OG). The ABS module shares the HS-CAN with the instrument cluster and the powertrain control module (PCM). Power for the ABS module is provided by circuit 1087 (OG), and ground is provided by circuit 1203 (BK/LB).

Possible Causes
- Fuse
- Circuit 1087 (OG) open
- Circuit 1203 (BK/LB) open
- Circuit 1847 (WH/OG) open (HS-CAN +)
- Circuit 1848 (PK/OG) open (HS-CAN -)
- ABS module
