Normal Operation
The PCM 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 PCM. The PCM shares the HS-CAN network with the anti-lock brake system (ABS)
module and the instrument cluster.
