Normal Operation
The compass sensor module receives voltage from the smart junction box (SJB) through circuit CBP31 (BU/OG) and is grounded through circuit GD133 (BK). The compass sensor module communicates the vehicle direction to the instrument cluster through the compass communication data plus circuit VMC31 (YE/GN) and compass communication data minus circuit VMC30 (BU/GY).

DTC U2013 - is a continuous memory and on-demand DTC that sets if the instrument cluster is missing the compass data from the compass module.

Possible Causes
- Fuse
- Circuitry
- Compass module
- Instrument cluster
