Odometer: Description and Operation
ODOMETER
The IPC displays the vehicle mileage and trip mileage as determined by the ECM. The IPC calculates the vehicle mileage based on the speed pulses from
the 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.
