The PCM continually monitors the vehicle speed pulse information received from the vehicle speed sensor or the Controller Anti-lock Brake (CAB) and
engine speed pulse information received from the crankshaft position sensor, then sends the proper distance and engine speed messages to the instrument
cluster. For further diagnosis of the odometer/trip odometer or the instrument cluster circuitry that controls these functions, refer to testing.
For proper diagnosis of the vehicle speed sensor, the crankshaft position sensor, the CAB, the PCM, the PCI data bus, or the electronic message inputs to
the instrument cluster that control the odometer/trip odometer, a diagnostic scan tool is required.
