Normal Operation
The compass sensor module receives voltage from central junction box (CJB) fuse 27 (5A) through circuit 1003 (GY/YE) and is grounded through
circuit 875 (BK/LB). The compass sensor module communicates the vehicle direction to the instrument cluster, and the direction is displayed in the
message center. The compass sensor module uses circuit 702 (WH/BK) and circuit 703 (WH/OG) to communicate to the instrument cluster.
