The ABS module communicates with the scan tool through the 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 with the PCM, the restraints control module (RCM) and the
instrument cluster (IC). Voltage for the ABS module is provided by circuit 640 (RD/YE). Circuit 530 (LG/YE) provides ground.
