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.
