Test G: The Speedometer/Odometer Is Inoperative

PINPOINT TEST G: THE SPEEDOMETER/ODOMETER IS INOPERATIVE

Normal Operation
The instrument cluster (IC) receives the vehicle speed sensor (VSS) signal from the PCM over the high speed controller area network (HS-CAN). The instrument cluster (IC) monitors the VSS input from the PCM and commands the speedometer with a corresponding movement of the pointer.

The odometer indicates the vehicle distance traveled whenever the ignition switch is in the RUN position, based upon rolling count data sent from the PCM over the HS-CAN. The instrument cluster (IC) provides a reset button to allow the trip odometer to be reset to 0. When the reset button is pressed, the trip odometer is reset. The trip odometer accumulates and registers up to 999.9 kilometers or 999.9 miles.

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