Front Controls Display Interface Module (FCDIM) fault code (Freelander 2)

Front Control Unit/Display Interface Unit

NOTE: If a module or component failure is suspected and the vehicle remains under manufacturer's warranty, refer to the Warranty Guide (Section B1.2) or determine if there is a previously approved special program in effect before replacing the component.

NOTE: Generic scan tools may not be able to read the codes listed or may only be able to read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the listed 7-digit code to identify the fault (the last 2 digits provide additional information readable by the manufacturer-approved diagnostic system).

NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) with three decimal places of accuracy and a valid calibration certificate. When testing resistance, be sure to include the resistance of the DMM leads.

NOTE: Before starting diagnostic programs using fault location tests, check and correct basic faults.

NOTE: Inspect the connectors for signs of water ingress and their pins for damage and/or corrosion.

NOTE: If DTCs are set and the fault is not present after performing the troubleshooting tests, an intermittent problem may be the cause. Be sure to check for loose connections and corroded terminals.
