The compass display is incorporated into the Front Display Interface Module (FDIM) for vehicles without navigation.
For vehicles with navigation, the compass display is incorporated into the Audio Control Module (ACM). Refer to INFORMATION AND ENTERTAINMENT SYSTEMS .
Normal Operation
The compass display (located in the Front Display Interface Module (FDIM)) receives battery voltage from the Smart Junction Box (SJB) fuse 14 (10A) through circuit SBP14 (BN/RD). Ground for the FDIM is supplied through circuit GD114 (BK/BU). The compass module provides vehicle directional inputs to the Instrument Cluster (IC), which sends the compass information to the FDIM over the Medium Speed Controller Area Network (MS-CAN). The FDIM will display the compass direction according to the information that has been provided by the compass module to the IC.
- DTC B2097 (Compass Module Failure) - sets when the IC attempts a self-test of the compass module and its associated circuits and a failure results.
- DTC U2013 (Compass Module is Not Responding) - sets when the IC does not receive any communications from the compass module.
This pinpoint test is intended to diagnose the following
- Fuses
- Wiring, terminals or connectors
- Compass module
- FDIM (compass display)
- IC
