Test H: The Speedometer/Odometer Is Inoperative

PINPOINT TEST H: THE SPEEDOMETER/ODOMETER IS INOPERATIVE

Normal Operation
The instrument cluster (IC) receives the vehicle speed information from the PCM over the communication network and displays it on the speedometer. If the instrument cluster (IC) receives no vehicle speed signal after 1 second, the speedometer defaults to 0.

The instrument cluster (IC) receives an odometer message from the PCM and stores the mileage in memory. When the instrument cluster (IC) fails to receive the odometer message for more than 2 seconds, the odometer displays dashes.

This pinpoint test is intended to diagnose the following:
- PCM
- Instrument cluster (IC)
