Messaged Inputs

Module messaging has increased over time and is slowly becoming the standard for sending and receiving information required to operate the IC. The IC is a gateway module. As a gateway module, the IC receives and sends information to other modules over both the High Speed Controller Area Network (HS-CAN) and the Medium Speed Controller Area Network (MS-CAN) that may not necessarily be used for IC gauge or indicator outputs.

For additional information and a complete list of all module messages along with the message origination sources, refer to MODULE COMMUNICATIONS NETWORK .

Some of the system status and information messages that the IC requires from other modules to operate the gauges and indicators are as follows:

• Vehicle speed
• Engine rpm
• Engine Coolant Temperature (ECT)
• ABS
• Stability/traction control status
• Four-Wheel Drive (4WD)
• Odometer rolling count
• TPMS
• Supplemental Restraint System (SRS)
• Brake fluid level
• Parking brake status
• Electronic Throttle Control (ETC)
