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 indicators illuminate briefly at key up:

Refer to Indicator/Warning Message Description and Operation .

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 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 gauge defaults to E (empty) if:

When the fuel level is less than a pre-determined value, the DIC displays the LOW FUEL message.

The IPC contains a season odometer and 2 trip odometers. A momentary press of the trip/reset switch on the IPC toggles the odometer between the season odometer and the trip odometer. A momentary press of the trip A/B switch while the trip odometer is displayed toggles the trip odometer between trip A and trip B. If the trip/reset button is pressed for greater than 1 second while either the trip A odometer or the trip B odometer is displayed, that trip odometer resets to 0.

The IPC calculates the mileage based on the vehicle speed signal circuit from the PCM. The odometer displays either miles or kilometers as requested by the driver information center (DIC). The associated indicator (km or MI) 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 does not display a gear if:

The IPC displays the vehicle speed based on the information from the vehicle speed sensor. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4000 pulses/mile) 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 (4000 pulses/mile) exists. The speedometer displays either miles or kilometers as requested by the driver information center (DIC). The associated indicator (km/h or MPH) illuminates.

The IPC displays engine speed based on information from the powertrain control module (PCM). The PCM converts the data from the engine speed sensor to a 2 pulses/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.
