Pinpoint Test

1. Ignition OFF.
2. Disconnect: DCSM C3265A.
3. Ignition ON.
4. Measure:

   DCSM			Ground
   C3265A			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   E	CBX01 (GN/RD)		-	-
   F	CBX01 (GN/RD)		-	-

Are the voltages greater than 11 volts? 

1. Yes: GO to 2  .
2. No: VERIFY the BJB fuse 28 (30A) is OK. If OK, REPAIR the circuit in question. 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. Measure:

   DCSM			Ground
   C3265A			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   M	GD903 (BK/WH)		-	-

Is the resistance less than 3 ohms? 

1. Yes: GO to 3  .
2. No: REPAIR the circuit.

1. Disconnect: DCSM C3265C.
2. Measure:

   LTM			DLC
   C3265C			C251
   Pin	Circuit	Measurement	Pin	Circuit
   1	VDB06 (GY/OG)		3	VDB06 (GY/OG)
   2	VDB07 (VT/OG)		11	VDB07 (VT/OG)

Are the resistances less than 3 ohms? 

1. Yes: GO to 4  .
2. No: REPAIR the circuit in question.

1. Ignition OFF.
2. Disconnect and inspect the DCSM connectors.
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 DCSM connectors. Make sure they seat and latch 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 DCSM. REFER to DUAL CLIMATE CONTROLLED SEAT MODULE (DCSM) .
2. No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
