Test C: The Compass Is Inoperative

PINPOINT TEST C: THE COMPASS IS INOPERATIVE

Normal Operation
The compass module (without auto-dimming interior rear view mirror) or interior rear view mirror (with auto-dimming interior rear view mirror) receives voltage from the central junction box (CJB) through circuit 294 (WH/LB) and is grounded through circuit 875 (BK/LB). The compass module (without auto-dimming interior rear view mirror) or interior rear view mirror (with auto-dimming interior rear view mirror) communicates vehicle direction to the instrument cluster (IC) to be displayed in the message center. The compass module (without auto-dimming interior rear view mirror) or interior rear view mirror (with auto-dimming interior rear view mirror) uses circuits 702 (WH/BK) and 703 (WH/OG) to communicate to the instrument cluster (IC).

- DTC U2013 (Compass Module is Not Responding) - is a continuous memory DTC that sets in the instrument cluster (IC) if the compass module (without auto-dimming interior rear view mirror) or interior rear view mirror (with auto-dimming interior rear view mirror) does not send the compass data to the instrument cluster (IC).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Compass module (without auto-dimming mirror)
- Interior rear view mirror (with auto-dimming mirror)
- Instrument cluster (IC)
