Pinpoint Test

1. Using a scan tool, perform BCM self-test.
2. Record all BCM DTCs  .

Is DTC B1240:11 present? 

1. Yes:  GO to 2  .
2. No  : If DTC B1240:15 is present, GO to 3  .

   For all other BCM DTCs  , REFER to DTC CHART: BODY CONTROL MODULE (BCM) .

   If no BCM DTCs  are present, GO to 5  .

1. Ignition OFF.
2. Disconnect: BCM C2280B.
3. Disconnect: Start/Stop Switch.
4. Measure:

   Start/Stop switch			Ground
   C2195			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   2	CPK36 (VT/BN)		-	Ground

Is the resistance to ground greater than 10, 000 ohms? 

1. Yes:  INSTALL a new start/stop switch. REFER to Start-Stop Switch .
2. No  : REPAIR the circuit.

1. NOTE: Disconnecting BCM C2280B with the ignition in RUN mode causes DTCs  to set in some modules.

   Ignition ON.

2. Disconnect: BCM C2280B.
3. Disconnect: Start/Stop Switch.
4. Measure:

   Start/Stop Switch			Ground
   C2195			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   2	CPK36 (VT/BN)		-	Ground

Is any voltage present? 

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

1. Ignition OFF.
2. Disconnect: BCM C2280B.
3. Measure:

   Start/Stop Switch			BCM
   C2195			C2280B
   Pin	Circuit	Measurement / Action	Pin	Circuit
   2	CPK36 (VT/BN)		42	CPK36 (VT/BN)

Is the resistance less than 3 ohms? 

1. Yes:  INSTALL a new start/stop switch. REFER to Start-Stop Switch .
2. No  : REPAIR the circuit.

1. Ignition OFF.
2. Disconnect: BCM C2280B.
3. Connect a fused jumper wire:

   BCM			Battery
   C2280B			Battery Positive Post
   Pin	Circuit	Fused Jumper	Pin	Circuit
   42	CPK36 (VT/BN)		-	Battery positive post

Does the start/stop switch mode indicator illuminate? 

1. Yes:  REMOVE the fused jumper wire. GO to 6  .
2. No  : INSTALL a new start/stop switch. REFER to Start-Stop Switch .

1. Disconnect and inspect all BCM connectors.
2. 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
3. Reconnect the BCM connectors and all previously disconnected exterior system connectors. Make sure they seat and latch correctly.
4. Operate the system and determine if 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 BCM. REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) , or REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) .
2. 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.
