Pinpoint Test

CHECK THE RECORDED DTCs FROM THE BCM SELF-TEST
1. Ignition ON.
2. Using a scan tool, perform the BCM on-demand self-test.
Is DTC B1D35:11 present?
- Yes: GO to 2 .
- No: GO to 4.
ISOLATE THE FCIM AS THE CAUSE OF DTC B1D35:11
1. Ignition OFF.
2. Disconnect: FCIM.
3. Ignition ON.
4. Using a scan tool, perform BCM on-demand self-test.
Is DTC B1D35:11 still present?
- Yes: GO to 3 .
- No: GO to 6.

CHECK THE HAZARD LAMP REQUEST INPUT CIRCUIT FOR A SHORT TO GROUND

Ignition OFF.
Disconnect: BCM C2280B.

Measure:

FCIM			Ground

C2402			Ground
Pin	Circuit	Measurement / Action	Pin	Circuit
4	CLS32 (BN/YE)		-	Ground

Is the resistance greater than 10, 000 ohms?

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

CHECK FOR A VOLTAGE SIGNAL TO THE FCIM

Disconnect: FCIM.
Ignition OFF.

Measure:

FCIM			Ground

C2402			Ground
Pin	Circuit	Measurement / Action	Pin	Circuit
4	CLS32 (BN/YE)		-	Ground

Is the voltage greater than 11 volts?

Yes: GO to 6.
No: GO to 5 .

CHECK THE HAZARD FLASHER LAMP REQUEST INPUT CIRCUIT FOR AN OPEN

Disconnect BCM C2280B.

Measure:

BCM			FCIM

C2280B			C2402
Pin	Circuit	Measurement / Action	Pin	Circuit
32	CLS32 (BN/YE)		4	CLS32 (BN/YE)

Is the resistance less than 3 ohms?

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

CHECK FOR CORRECT FCIM OPERATION
1. Disconnect and inspect all FCIM 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 FCIM connectors. Make sure they seat and latch correctly.
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 FCIM. REFER to FRONT CONTROLS INTERFACE MODULE (FCIM) - (Premium).
- 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.
CHECK FOR CORRECT BCM OPERATION
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.
