Instrument Panel Cluster (IPC) Description and Operation: Odometer

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

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 engine control module (ECM)/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

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.
The season odometer cannot be reset.
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
