Information And Message Center
Information And Message Center
NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).
The message center is a fixed format display, integrated into the Instrument Panel Cluster (IPC). The message center functions are controlled by the message center switch. The message center displays important vehicle information by constantly monitoring different vehicle systems. The message center informs the driver of vehicle operations and notifies the driver of vehicle conditions or potential problems by displaying a warning message pertaining to the system in which the driver may require information or if a system fault has been detected.
The message center switch is located in the center of the IPC (Instrument Panel Cluster).
The message center provides the following features:
- Information displays
- Setup displays
- System check messages
- System warning messages
The message center information can be selected through a set of 3 buttons:
- INFO
- SETUP
- RESET
Message Center Configuration
The message center has the capability to configure items such as units (English or metric), autolamp delay, to enable/disable a variety of options such as autolock, auto-unlock and easy entry/easy exit (if equipped).
On configurable items such as autolock, auto-unlock or easy entry/easy exit, the message center indicates the appropriate selection (ON/OFF) by bracketing the selection. For example, if the driver selects the autolock feature on, the message would display as follows: AUTOLOCK [ON> OFF. If the driver selects the autolock off, the message would display as follows: AUTOLOCK ON [OFF>.
Oil Change Minder
NOTE: On early build vehicles, the PCM uses time and distance calculations stored in Keep Alive Memory (KAM) in the PCM to help determine the oil change minder status. If the PCM KAM (Keep Alive Memory) is reset or lost for any reason (battery disconnect, PCM disconnect or dead battery), the oil change minder is disabled and the oil life reset procedure needs to be carried out through the message center to re-enable the oil minder function.
The message center provides an oil change minder to inform the driver that an oil change is required. The duration of the interval between oil changes is calculated in the PCM, and varies due to driving conditions. The PCM assumes a base mileage of 16,093 km (10,000 miles) or 1 year for normal driving. However, this number will be adjusted down due to high engine temperature, high engine rpms, use of flex fuel and possibly low oil level. The PCM calculates and provides an oil life status message to the IPC (Instrument Panel Cluster). The IPC (Instrument Panel Cluster) further converts the remaining oil life using the driver's configured oil life start value and displays the oil life percentage, indicating the remaining oil life. The oil change minder can be reset at any time by the driver. Refer to Message Center Configuration Service and Repair.
Oil Life and Oil Life Start Value
The oil life is displayed in percentages. The oil life start value is used to increase or decrease the starting point of the oil life. The oil life start value can be changed back to the maximum of approximately 16,093 km (10,000 miles) if the value was previously changed or to lower the value by 10% increments down to 10%. Each 10% reduction lowers the oil life in both mileage and time (days).
Compass Display
The electronic compass system consists of:
- Compass sensor (integral to the auto-dimming interior mirror)
- Compass display (in the lower LH corner of the Front Display Interface Module (FDIM)) (vehicles without navigation)
- Compass display (in the upper RH corner of the FDIM (Front Display Interface Module)) (vehicles with navigation)
- Instrument Panel Cluster (IPC) (serves as the compass gateway module interface between the compass sensor and the compass display)
Without Navigation
The compass signal originates from the compass module, which is integrated into the auto-dimming interior mirror.
The compass reading is incorporated into the Front Display Interface Module (FDIM).
The vehicle heading is displayed as a 1 or 2 character display located in the lower LH corner of the FDIM (Front Display Interface Module) and indicates the current direction of the vehicle (N, NE, E, SE, S, SW, W, or NW). The compass continuously re-calibrates due to changes in the magnetic field and remains accurate during most driving conditions.
The Front Controls Interface Module (FCIM) buttons that allow the driver to operate (change) the calibration and zone setting procedures are located below the FDIM (Front Display Interface Module).
The compass display is on with the ignition in the ON or START position. When the ignition is first turned to the ON or START position, there is a momentary delay of approximately 6 seconds before the compass display illuminates. If the battery saver has been activated and the ignition is turned to ON or START, the momentary delay before the compass display illuminates is approximately 3 seconds. The compass display turns off as soon as the ignition is turned to the OFF or ACC position.
With Navigation
The compass signal originates from the Global Positioning System (GPS) antenna. No calibration or zone adjustment is available, as the compass heading is based on the GPS (Global Positioning System) signal. for information on the GPS (Global Positioning System) signal.
Compass Accuracy (Without Navigation)
Driving near power lines, or driving in the area of large iron or steel structures can temporarily change the compass heading. If the compass remains inaccurate after driving near such objects, calibrate the compass. Refer to Compass Calibration .
Most geographic areas (zones) have a magnetic north compass point that varies slightly from the northerly direction on maps. This variation is 4 degrees between the adjacent zones and becomes noticeable as the vehicle crosses multiple zones. A correct zone setting eliminates the error. Refer to Compass Zone Adjustment .
Information Displays
The information displays are non-timed modes. The selected mode remains on until the driver presses a message center button to change the mode or it is overridden by another mode.

System Check
The system check provides a check of all the monitored systems on the vehicle. The system check scrolls through each of the monitored systems and provides a visual indication to report out the status of each system. The message center displays OK for approximately 2 seconds if the system check does not detect a concern or fault in the system and displays a warning message for approximately 2 seconds if the system check detects a concern or fault in the system. From the SETUP menu, press the RESET button to scroll through the system check messages.
