REPAIR the circuit.

K5 CHECK FOR CORRECT FCIM (FRONT CONTROLS INTERFACE MODULE) OPERATION

Ignition OFF. Disconnect and inspect all the FCIM connectors and related in-line connectors. Repair:

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

Reconnect the FCIM connectors and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new FCIM. For AM/FM/CD /SYNC, REFER to: Front Controls Interface Module (FCIM) (415-00A Information and Entertainment System - General Information - Vehicles With: AM/FM/CD/SYNC, Removal and Installation).

For touchscreen display, REFER to: Front Controls Interface Module (FCIM) (415-00B Information and Entertainment System - General Information - Vehicles With: Touchscreen Display, Removal and Installation).

No

The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
