Each instrument cluster (IPC) is equipped with a season odometer and 2 trip odometers. The IPC uses the odometer rolling count message from the PCM. The rolling count value is determined by counting the speed pulses from the vehicle speed signal (VSS). The IPC uses the rolling count data from the PCM and a software program to determine vehicle mileage. The odometers can be displayed in miles or kilometers. The units displayed is miles or kilometers. The units displayed is switched between English and metric by pressing the E/M button on the DIC (if equipped). When the E/M button is pressed to show the odometer in metric, km and the number will be displayed. When the odometer is in English, only the number will be displayed. During a bulb check all segments on the odometer including A, B and the word TRIP illuminate for 5 seconds.
