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, 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.

DTC B2097 - is a continuous memory DTC that sets in the instrument cluster if the data received from the compass module is invalid.

DTC U2013 - is a continuous and on-demand DTC that sets if the instrument cluster fails to receive a response from the compass module after 4 consecutive attempts.

Possible Causes
- Fuse
- Circuit CBP18 (GY/OG) open
- Circuit GD143 (BK/VT) open
- Circuit VMC30 (BU/GY) open or short to ground
- Circuit VMC31 (YE/GN) open or short to ground
- - Compass sensor module
