Module, Compass: Operation: Notes
The Remote Compass Module (RCM) uses both non-switched and ignition switched sources of battery current so that some of its features remain operational at any time, while others may only operate with the ignition switch in the ON position. When the ignition switch is turned to the ON position, the RCM display (34) will return to the last function being displayed before the ignition was turned to the OFF position.
The RCM system includes several different components that communicate over the Controller Area Network (CAN) and Local Interface Network (LIN) data buses. If the RCM system is ineffective, a diagnostic scan tool and the appropriate diagnostic information must be used to diagnose the system and the related data buses.
The push buttons of the Electronic Vehicle Information Center (EVIC) switch pod in the left horizontal spoke of the steering wheel are used to navigate through the different functions of the RCM system. Pressing and releasing the STEP button will scroll through the following RCM displays:
- Compass/Temperature
- Average Fuel Economy (AVG ECO)
- Distance To Empty (DTE)
- Elapsed Time (ET)
Once a resettable function or feature is displayed, pressing and holding the RESET button will reset that resettable function or feature. A reset will only occur if a resettable function or feature is currently being displayed.
The instrument cluster button (24) is the odometer and trip odometer select and reset button, which is used to navigate through the different functions and features of the odometer system. Pressing and releasing this button will scroll through the following displays:
- Odometer (ODO)
- Trip Odometer A (TRIP A)
- Trip Odometer B (TRIP B)
- Fuel saver indicator, Economizer (ECO) display (if equipped)
Once a resettable function or feature is displayed, pressing and holding the odometer and trip odometer reset and select push button will reset that resettable feature or function. Reset will only occur if a resettable function or feature is currently being displayed.
