Test B: The Compass Is Inoperative

PINPOINT TEST B: THE COMPASS IS INOPERATIVE

Normal Operation
The compass module receives voltage from the SJB through circuit CBP31 (BU/OG) and is grounded through circuit GD133 (BK). The compass module communicates vehicle direction to the instrument cluster to be displayed in the message center. The compass module uses communication data plus circuit VMC31 (YE/GN) and communication data minus circuit VMC30 (BU/GY) to communicate to the instrument cluster.

DTC B2097 (Compass Module Failure) - sets in continuous memory and on-demand in the instrument cluster if the instrument cluster detects invalid data sent from the compass module during the self-test.

DTC U2013 (Compass Module Is Not Responding) - sets in continuous memory in the instrument cluster if the compass data is invalid from the compass module. The DTC is also set on-demand if the compass module fails to respond during a self-test. If the instrument cluster fails to receive the compass data, the instrument cluster sets DTC U2013 and defaults the compass display to (--).

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