Pinpoint Test S: The Audio System Does Not Operate Correctly From The Front Controls Interface Module (FCIM)

Normal Operation

When a button is touched on the Front Controls Interface Module (FCIM), a signal is broadcast over the Infotainment Controller Area Network (I-CAN) to the modules in the audio system. The FCIM (Front Controls Interface Module) is also the customer interface with the HVAC module.

- DTC U2013:63 (Switch Pack: Circuit / Component Protection Time-Out)- set by the FCIM (Front Controls Interface Module) if a switch is detected as active for more than 3 seconds during the self-test, or for more than 2 minutes during normal operation. When this occurs, the FCIM (Front Controls Interface Module) disables the switch until it detects it as no longer active.

This pinpoint test is intended to diagnose the following:

- Communication network concern

- FCIM (Front Controls Interface Module)

PINPOINT TEST S : THE AUDIO SYSTEM DOES NOT OPERATE CORRECTLY FROM THE FCIM (Front Controls Interface Module)

S1 CHECK FOR DTC U2013:63
