Messaged Inputs

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

Module messaging has increased dramatically over time and is slowly becoming the standard for sending and receiving information required to operate the instrument cluster. The instrument cluster is a gateway module. As a gateway module, the instrument cluster 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 instrument cluster 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 instrument cluster requires from other modules to operate the gauges and indicators are as follows:

Vehicle speed
Engine rpm
Engine coolant temperature
ABS
Traction control status
All wheel drive (AWD)
Transmission range status
Overdrive (O/D) status
Tire pressure monitoring system (TPMS)
Supplemental restraint system (SRS)
Brake fluid level
Parking brake status
Electronic throttle control (ETC)
