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 occurs at key up:

Refer to Indicator/Warning Message Description and Operation .

The instrument panel cluster (IPC) displays the engine coolant temperature (ECT) as determined by the powertrain control module (PCM) or the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the ECT. The range on the ECT gage is between 60-125°C (140-260°F). The ECT gage defaults to 60°C (140°F) or below if the PCM detects a malfunction in the ECT sensor circuit. Refer to Cooling System Description and Operation .

The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to E (empty) if the PCM detects a malfunction in the fuel level sensor circuit. Refer to Powertrain Control Module Description .

When the fuel level is less than 11 percent (less than 1/16 tank) of a tank of gas, the LOW FUEL message illuminates in the message center.

The instrument panel cluster (IPC) contains a season odometer and a trip odometer. Press the trip/reset switch for 1 second on the IPC in order to toggle between the season odometer and the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates the mileage based on the vehicle speed signal circuit from the powertrain control module (PCM). The odometer will display ERROR if an internal IPC memory malfunction is detected or there is a class 2 communication fault. The odometer displays either miles or kilometers as requested by the activation of the english/metric button on the driver information center (DIC). The associated indicator (km or mi) illuminates.

Season Odometer

1. The season odometer is capable of displaying 99999.9 miles. When the season odometer hits 99999.9 miles it will not roll over to 00000.0, it stays at its maximum level of 99999.9.
2. The season odometer cannot be reset.
3. The season odometer is functional with the ignition OFF. With the ignition OFF and the driver door closed, press the trip/reset button and the season odometer stays on for 5 seconds and then turns OFF. When the ignition is OFF and the driver door is open, the season odometer stays ON for 15 seconds.

Trip Odometer

1. The trip odometer is capable of displaying 99999.9 miles. When the trip odometer hits 99999.9 miles it will roll over to 00000.0.
2. Press the trip/reset switch for greater than 1 second, while the trip odometer is displayed, in order to reset the trip odometer.

The instrument panel cluster (IPC) displays the vehicle speed as determined by the powertrain control module (PCM). The PCM converts the data from the vehicle speed sensor to a 4,000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4,000 pulses/mile), class 2 message from the PCM in order to calculate the vehicle speed. If the IPC detects a malfunction in the vehicle speed signal circuit from the PCM, the IPC uses the class 2 message from the EBCM, indicating the vehicle speed as a backup. If the speedometer reaches (108 mph) the fuel will shut-off, and it will turn back ON when the speedometer is at (106 mph). The speedometer displays either miles or kilometers as requested by the activation of the english/metric button on the driver information center (DIC). The associated indicator (km/h or mph) illuminates.

The instrument panel cluster (IPC) displays the engine speed as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine speed. The IPC is capable of displaying between 0-7,000 RPM. The tachometer will default to 0 RPM if the PCM detects a malfunction in the engine speed sensor signal circuit.
