Pinpoint Test I: The Front Display Interface Module (FDIM) Is Completely Inoperative

Normal Operation

The Front Display Interface Module (FDIM) receives voltage from the Smart Junction Box (SJB). The ignition switch position message is broadcast to the FDIM by the SJB via the Medium Speed Controller Area Network (MS-CAN).

Information from the audio system (vehicles without navigation), the climate control system, the SYNC system (if equipped), and the compass heading (if equipped) are shown on the FDIM display screen. If only one of these displays has a concern, GO to Pinpoint Test K. Pinpoint Test K: An Individual Front Display Interface Module (FDIM) Display Is Inoperative/Does Not Operate Correctly - Vehicl

This pinpoint test is intended to diagnose the following:

- Communication network concern
- FDIM
