Test B: The Compass Is Inoperative

PINPOINT TEST B: THE COMPASS IS INOPERATIVE

Normal Operation
The compass sensor module receives voltage from the smart junction box (SJB) through circuit CBP18 (GY/OG) and is grounded through circuit GD143 (BK/VT). The compass sensor module communicates the vehicle direction to the instrument cluster (IC), which is displayed in the message center. The compass sensor module uses circuits VMC30 (BU/GY) and VMC31 (YE/GN) to communicate to the instrument cluster (IC).

- DTC B2097 (Compass Module Failure) - is a continuous memory DTC that sets in the instrument cluster (IC) if the data received from the compass module is invalid.
- DTC U2013 (Compass Module is Not Responding) - is a continuous and on-demand DTC that sets if the instrument cluster (IC) fails to receive a response from the compass module after 4 consecutive attempts.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Compass sensor module
