CJ1 CHECK THE SEATBELT WARNING CHIME OPERATION
- Ignition OFF.
- Ignition ON.
- Monitor the seatbelt warning chime when the ignition switch is transitioned from OFF to RUN for 6 seconds.
Does the seatbelt warning chime operate for approximately 6 seconds?

Yes GO to CJ2

No GO to Pinpoint Test CQ

CJ2 CHECK THE INTERIOR LAMPS OPERATION
- Open and close the driver door.
- Observe the interior lamps.
Do the interior lamps operate correctly from the driver door?

Yes GO to CJ3

No REFER to: Interior Lighting .

CJ3 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?

Yes REFER to: Communications Network .

No GO to CJ4

CJ4 PERFORM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC B10F1:14 present?

Yes GO to CJ5

No GO to CJ8

CJ5 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE

Ignition OFF.

Insert the key into the ignition cylinder.

Disconnect BCM C2280D.

Measure:

Is the resistance less than 3 ohms?

Yes	REPAIR the circuit.

No	DIAGNOSE the ignition switch. REFER to: Steering Wheel and Column Electrical Components .

CJ8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the BCM connectors.

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

Reconnect the BCM connectors. Make sure they seat and latch correctly.

Operate the system and verify the concern is still present

Is the concern still present?

Yes

CHECK On-Line Automotive Service Information System (OASIS) for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, Refer to BCM GUIDED ROUTINE

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.
