Messaged Inputs

Module messaging has increased dramatically over time and is slowly becoming the standard for sending and receiving information required to operate the instrument cluster (IC). For additional information and a complete list of module messages with the message origination sources, refer to MODULE COMMUNICATIONS NETWORK article.

The status and information messages that the instrument cluster (IC) requires from other vehicle systems are as follows:

• Vehicle speed
• Engine temperature
• Engine RPM
• ABS
• 4WD
• Transmission range
• O/D status
• TPMS
• SRS
• Brake fluid level
• Parking brake status
• Engine emission system
