Odometer: Description and Operation

ODOMETER

The instrument panel cluster (IPC) displays the vehicle mileage and trip mileage as determined by the engine control module (ECM). The IPC calculates the vehicle mileage based on the speed pulses from the vehicle speed sensor (VSS) signal and calculating the mileage for odometer displays. The odometer will display Error if an internal IPC memory failure is detected and DTC B1009 is set.
