Odometer: Description and Operation
ODOMETER
The base IPC contains a season odometer and a trip odometer. The uplevel IPC contains a season odometer and two trip odometers. Momentarily press
the trip/reset switch on the IPC in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2
seconds, while the trip odometer is displayed, 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 Personalization button on the steering wheel
controls.
