Front Controls/Display Interface Module (FCDIM)
CAUTION:
Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
CAUTION:
When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00
NOTE:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the warranty policy and procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a new module/component.
NOTE:
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system)
NOTE:
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account
NOTE:
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests
NOTE:
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
NOTE:
If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals
NOTE:
Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the manufacturers approved diagnostic system
The table below lists all diagnostic trouble codes (DTCs) that could be logged in the front controls/display interface module, for additional diagnosis and testing information. For additional information, refer to: INFORMATION AND ENTERTAINMENT SYSTEM - GENERAL INFORMATION .
| DTC | Description | Possible Cause | Action |
|---|---|---|---|
| U1A01-15 | Communication Link - circuit short to battery or open |
|
Carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. Refer to the electrical circuit diagrams and check TSD to navigation module circuit for short to power, open circuit. |
| U1A4B-48 | Control Module Processor B - supervision software failure |
|
Re-configure the TSD using the manufacturer approved diagnostic system. |
| U3000-48 | Control Module - supervision software failure |
|
Re-configure the TSD using the manufacturer approved diagnostic system. |
| U3000-4B | Control Module - over temperature |
|
Allow the system to cool, clear the DTC and check/monitor system for re-occurrence. If DTC re-occurs suspect the TSD. Check and install a new TSD as required, refer to the new module/component installation note at the top of the DTC Index. |
| U3000-55 | Control Module - not configured |
|
Check/amend Car Configuration File using the manufacturer approved diagnostic system. |
| U3000-87 | Control Module - missing message |
|
Check RJB for related DTCs and refer to relevant DTC Index. Check CAN and MOST networks, carry out the CAN and MOST network tests using the manufacturer approved diagnostic system. |
| U3000-98 | Control Module - component or system over temperature |
|
Allow the system to cool, clear the DTC and check/monitor system for re-occurrence. If DTC re-occurs suspect the TSD. Check and install a new TSD as required, refer to the new module/component installation note at the top of the DTC Index. |
| U3003-16 | Battery Voltage - circuit voltage below threshold |
|
Carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. |
| U3003-17 | Battery Voltage - circuit voltage above threshold |
|
Carry out any pinpoint tests associated with this DTC using the manufacturer approved diagnostic system. |
