Pinpoint Test

1. Press the lock and unlock button on a door lock control switch and IA key while observing the door lock operation.

Are the door locks inoperative from both the switch and IA key? 

• Yes: GO to 2  .
• No: If the door locks are inoperative from the door lock control switch, REFER to Diagnostic Routine D: All Door Locks Are Inoperative From One Switch .

  If the door locks are inoperative from the IA key, REFER to Diagnostic Routine J: The Remote Keyless Entry (RKE) Transmitter Is Inoperative .

1. Press the lock and unlock buttons from a door lock control switch while observing the door locks.

Are all the door locks inoperative from both switch positions (lock and unlock)? 

• Yes: GO to 3  .
• No: CHECK the symptom(s). REFER to Symptom Chart: Handles, Locks, Latches and Entry Systems - Electrical .

1. Ignition OFF.
2. Disconnect: RFA Module C2153C.
3. Measure:

   RFA Module			Ground
   C2153C			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   5	SBP27 (BU)		-	Ground

Is the voltage greater than 11 volts? 

• Yes: GO to  5.
• No: VERIFY the BCM fuse 27 (20A) is OK. If OK, GO to 4  . If not OK, GO to 7  .

1. Disconnect: BCM C2280A.
2. Measure:

   RFA Module			BCM
   C2153C			C2280A
   Pin	Circuit	Measurement / Action	Pin	Circuit
   5	SBP27 (BU)		12	SBP27 (BU)

Is the resistance less than 3 ohms? 

• Yes: GO to  8.
• No: REPAIR the circuit.

1. Disconnect: RFA Module C2153D.
2. Measure:

   RFA Module			Ground
   C2153D			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   1	GD214 (BK/BU)		-	Ground

Is the resistance less than 3 ohms? 

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

1. Disconnect: RH Front Door Latch.
2. Measure:

   RFA Module			RH Front Door Latch
   C2153D			C609
   Pin	Circuit	Measurement / Action	Pin	Circuit
   2	CPL11 (GY/BN)		4	CPL11 (GY/BN)

Is the resistance less than 3 ohms? 

• Yes: GO to  9.
• No: REPAIR the circuit.

1. NOTE: If the BCM fuse 27 (20A) fails immediately upon installation, repair circuit SBP27 (BU) for a short to ground.

   Install a new BCM fuse 27 (20A).

2. Operate the door lock actuators by pressing lock on the door lock control switch.

Is the BCM fuse 27 (20A) OK? 

• Yes: REPAIR the driver door or passenger door unlock circuit for a short to ground.
• No: REPAIR the all lock circuit for a short to ground.

1. Ignition OFF.
2. Disconnect and inspect all BCM connectors.
3. 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
4. Reconnect the BCM connectors. Make sure they seat and latch correctly.
5. 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) - 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.
