High Speed Controller Area Network (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:

• 4X4 control module
• ABS module
• Instrument cluster (IC)
• Occupant classification system module (OCSM)
• PCM
• Power steering control module (PSCM)
• Restraints control module (RCM)
