Pinpoint Test

1. Ignition OFF.
2. Disconnect: FCDIM  .
3. Ignition ON.
4. Measure:

   FCDIM			Ground
   C2123			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   1	SBP09 (RD)		-	-

Is the voltage greater than 11 volts? 

1. Yes: GO to 2  .
2. No: VERIFY the BCM fuse 9 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS .

1. Ignition OFF.
2. Disconnect: Negative Battery Cable.
3. Measure:

   FCDIM			Ground
   C2123			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   9	GD214 (BK/BU)		-	-

Is the resistance less than 3 ohms? 

1. Yes: GO to 3  .
2. No: REPAIR the circuit. CONNECT the negative battery cable.

1. Disconnect: IPC.
2. Measure:

   FCDIM			IPC
   C2123			C220
   Pin	Circuit	Measurement	Pin	Circuit
   4	VDB13 (BU/GY)		25	VDB13 (BU/GY)
   5	VDB14 (VT/GY)		26	VDB14 (VT/GY)

Are the resistances less than 3 ohms? 

1. Yes: CONNECT the negative battery cable. GO to 4  .
2. No: REPAIR the circuit in question. CONNECT the negative battery cable.

1. Ignition OFF.
2. Disconnect and inspect the FCDIM  connector.
3. Repair:
   • corrosion (replace connector or terminals - clean module pins)
   • damaged or bent pins - replace terminals/pins
   • pushed-out pins - replace pins as necessary
4. Reconnect the FCDIM  connector. Make sure it seats and latches correctly.
5. Operate the system and verify the concern is still present.

Is the concern still present? 

1. Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs  address this concern, INSTALL a new FCDIM  . REFER to FRONT CONTROLS INTERFACE MODULE (FCIM) - (Premium).
2. No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
