General Description

Locations View:

The Instrument Panel Cluster (IPC) serves as the primary display unit for systems that require display functions. The IPC is capable of displaying system information and driver warning/status messages by using three different technologies:
^ Vacuum Fluorescent (VF) lighting
^ Ultraviolet lighting
^ Air core gauges

Located on the IPC is a 20-character vacuum florescent display referred to as the Driver Information Center (DIC). The DIC is used to display driver selectable information and warning/status messages. The DIC switches are located on the IPC and can be used to access any of the modes listed. For example, oil pressure can be displayed by pressing the GAGE button, and personalized option can be displayed by pressing the OPTIONS button. The following information can be assessed through the IPC display by selecting the following DIC switches:
^ FUEL
- Average
- Instantaneous
- Range
^ GAGE
- Oil pressure
- Oil temperature
- Coolant temperature
- Transmission temperature (Auto trans only)
- Battery voltage
- Front tire pressure
- Rear tire pressure
^ TRIP
- Odometer
- Trip A
- Trip B
- Elapse time
- Average speed
- Oil life remaining
^ OPTIONS
- Twilight
- Universal Theft Deterrent (UTD) functions
- Lock functions (passive and auto)
- Approach lighting
- Seat easy entry
- Languages
- Blank display (fob and tire training mode)
^ E/M

- Reset Fuel Economy Functions
- Customize Vehicle Electrical Functions
- Remote Function Actuation (RFA) programming
- Change personalized options
The IPC is also responsible for indicator illumination and chime functions. Some indicators are directly controlled by the IPC and others are controlled by a dedicated circuit to the IPC. The IPC controlled indicators are illuminated when a message is received on the serial data line to perform this function. Indicators that are illuminated by a dedicated wire to the IPC are controlled directly by other systems which provide all control functions. The IPC controls all chime functions and is able to determine what indicator is associated with a chime. The chime is integrated within the IPC and is not serviced separately.
