Certain instrument panel cluster (IPC) features are tested when the ignition is turned on in order to verify the features are working properly. The following illuminate briefly or flash at key up:

Refer to Indicator/Warning Message Description and Operation .

The average fuel economy is a function of distance divided by fuel used since the parameter was last reset. When the average fuel economy is displayed on the DIC, pressing the INFO RESET button on the DIC will reset the average fuel economy parameter. On vehicles equipped w/UY9, the average fuel economy parameter is only displayed on the DIC.

The average fuel economy displays either miles or kilometers as requested by the activation of the ENG/MET button on the driver information center (DIC). The associated indicator illuminates.

The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to C if:

The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:

The fuel range is the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions. The fuel range parameter cannot be reset by the driver. "LO" is displayed in the fuel range display when the range is calculated to be less than 64 km (40 miles). The fuel range displays either miles or kilometers as requested by the activation of the ENG/MET button on the driver information center (DIC). The associated indicator illuminates.

The IPC contains a season odometer and a trip odometer. Press the RESET TRIP A/B button for greater than 2 seconds in order to reset the trip odometer. The IPC calculates the mileage based on the vehicle speed signal circuit from the PCM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers as requested by the activation of the ENG/MET button on the driver information center (DIC). The associated indicator illuminates.

The IPC displays the selected gear position as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display blanks if:

The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 mph (0 km/h) if a malfunction in the vehicle speed signal circuit exists. The speedometer displays either miles or kilometers as requested by the activation of the ENG/MET button on the driver information center (DIC). The associated indicator illuminates.

On vehicles equipped w/UY9 the speedometer display configuration can be changed by using the DSPL MODE button. The speedometer can be configured in the following formats:

The IPC displays the engine speed based on information from the PCM. The PCM converts the data from the engine to a 2 pulses per engine revolution signal. The IPC uses the engine speed signal circuit from the PCM in order to calculate the engine speed. The tachometer defaults to 0 rpm if a malfunction in the engine speed signal circuit exists.

The IPC displays the system voltage as detected at the ignition 1 input of the IPC.
