HS-CAN Operation

The HS-CAN communicates using bussed messages. The HS-CAN uses an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. In addition to scan tool communication, this network allows sharing of information between all modules on the network.

The HS-CAN is a high speed communication network used for the following modules:

• Accessory protocol interface module (APIM) (if equipped)
• ABS module
• Instrument cluster (IC)
• Occupant classification system module (OCSM)
• PCM
• Restraints control module (RCM)
• Transmission control module (TCM) (if equipped)
• 4X4 control module
