Pinpoint Test

1. CHECK THE FDIM (Front Display Interface Module) TOUCHSCREEN OPERATION

1. Operate and observe the FDIM (Front Display Interface Module) touchscreen.

Is the FDIM (Front Display Interface Module) touchscreen inoperative or blank?








2. VERIFY THE FCIM (Front Controls Interface Module) PASS THE NETWORK TEST

1. Using a scan tool, perform the network test.

Does the FCIM (Front Controls Interface Module) pass the network test?








3. CHECK THE FCIM (Front Controls Interface Module) BUTTON PIDs (Parameter Identifications)

1. Using a scan tool, view the FCIM (Front Controls Interface Module) PIDs (Parameter Identifications).

2. NOTE: The button PIDs begin with the prefix "BTN_" and end with the indicated button. For example, PID BTN_EJECT correlates with the eject button on the FCIM (Front Controls Interface Module).

Monitor the FCIM (Front Controls Interface Module) button PIDs (Parameter Identifications).

Do the PID (Parameter Identification) states agree with the button presses?








4. RESET THE AUDIO SYSTEM MODULES AND RECHECK THE SYSTEM OPERATION

1. Disconnect the battery for 5 minutes, then reconnect it.

2. Turn the infotainment system on.

3. While pressing the buttons on the FCIM (Front Controls Interface Module), observe the FCIM (Front Controls Interface Module) operation.

Does the FCIM (Front Controls Interface Module) operate correctly?








5. CHECK FOR CORRECT FCIM (Front Controls Interface Module) OPERATION

1. Disconnect and inspect the FCIM (Front Controls Interface Module) connector.

2. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Reconnect the FCIM (Front Controls Interface Module) connector. Make sure it seats and latches correctly.
