Medium Speed Controller Area Network (MS-CAN) Operation

The MS-CAN communicates using bussed messages. The MS-CAN has 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 MS-CAN is a medium speed communication network used for the following modules:

• Audio control module (ACM)
• Front controls interface module (FCIM)
• Front display interface module (FDIM)
• HVAC module
• Instrument cluster (IC)
• Satellite digital audio receiver system (SDARS) module
• Smart junction box (SJB)
