Principles of Operation: Notes
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The message center is an integral part of the instrument cluster. The message center communicates with the powertrain control module (PCM) and the anti-lock brake system (ABS) module over the communication network.
It is very important to understand:
- where the input originates.
- all the information necessary in order for a feature to operate.
- which module(s) receive(s) the input or command message.
- whether the module which received the input controls the output of the feature, or whether it outputs a message over the CAN circuits to another module.
- which module controls the output of the feature.
The 3 message center functions are:
- Information menu
- Setup menu
- Warning messages
The message center information can be selected by pressing any of the following 3 buttons:
- INFO
- RESET
- SETUP
The setup display time-outs and defaults to the blank display function. The temporary alert display interrupts the current display to show the status of an event that has just happened. The warning display interrupts the current display until cleared or reset by the driver.
