Pinpoint Test 1: The Compass Is Inoperative

PINPOINT TEST 1: THE COMPASS IS INOPERATIVE - HYBRID

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 (BR/R). Ground for the compass display (FDIM) is supplied through circuit (B/L). The electronic compass (located on the interior rear view mirror) provides vehicle directional inputs to the instrument cluster, 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 electronic compass to the instrument cluster.B2097 (Electronic Compass Failure) - sets when the instrument cluster attempts a self-test of the electronic compass and its associated circuits and a failure results.U0155 (Lost Communication With Instrument Panel Cluster [IC] Control Module) - sets when the FDIM does not receive any network communication messages over the MS-CAN network between the instrument cluster and the FDIM.

Possible Causes
- Fuse(s)
- Wiring, terminals or connectors
- Electronic compass
- FDIM (compass display)
- Instrument cluster

Diagnostic Procedure

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: After installing a new electronic compass, always set the zone and calibrate the compass. Compass Calibration
