Test I: Incorrect Speedometer Indication

PINPOINT TEST I: INCORRECT SPEEDOMETER INDICATION

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.

NOTE: Items that may affect the speedometer accuracy are tire size and tire wear.

This pinpoint test is intended to diagnose the following:
- Tire size configuration
- Axle ratio configuration
- PCM concern
- Instrument cluster (IC)
