• Yes: REPAIR the circuit.
• No: GO to 6  .

1. Measure:

   BCM			Ground
   C2280B			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   4	CBP31 (BU/OG)		-	Ground

Is any voltage present? 

• Yes: REPAIR the circuit.
• No: GO to 7  .

1. Ignition OFF.
2. Disconnect: BCM C2280D.
3. Ignition ON.

Do the stoplamps continue to illuminate? 

• Yes: REPAIR the circuit.
• No: GO to  10.

1. Disconnect and inspect all PCM 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 PCM 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? 

• 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 PCM:

  REFER to POWERTRAIN CONTROL MODULE (PCM) - 2.0L GTDI , or

  REFER to POWERTRAIN CONTROL MODULE (PCM) - 3.5L TI-VCT .

• 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.

1. Disconnect and inspect all RFA module 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 RFA module 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? 

• 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 RFA module. REFER to REMOTE FUNCTION ACTUATOR (RFA) MODULE .
• 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.

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. Make sure they seat and latch correctly.
4. Operate the system and determine if the concern is still present.

Is the concern still present? 

• 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) .
• 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.
