Pinpoint Test

CHECK THE SAFETY BELT WARNING CHIME OPERATION
1. Ignition OFF.
2. Ignition ON.
3. Monitor the safety belt warning chime when the ignition is transitioned from OFF to RUN.
Does the safety belt warning chime operate for approximately 6 seconds?
1. Yes: GO to 2 .
2. No: INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) .
CHECK THE INTERIOR LAMPS OPERATION
1. Open and close the driver door.
2. Observe the interior lamps.
Do the interior lamps operate correctly from the driver door?
1. Yes: GO to 3 .
2. No: REFER to SYMPTOM CHART: INTERIOR LIGHTING .
RETRIEVE THE RECORDED DTCs FROM THE BCM SELF-TEST
1. Using a scan tool, perform the BCM self-test.
Is DTC B10F1:14 present?
1. Yes: GO to 4 .
2. No: GO to 6 .

CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE

Ignition OFF.
Insert the key into the ignition cylinder.
Disconnect: BCM C2280B.

Measure:

BCM			Ground

C2280B			Ground
Pin	Circuit	Measurement / Action	Pin	Circuit
34	CDC30 (BU/GY)		-	Ground

Is the voltage greater than 11 volts?

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

CHECK THE IGNITION SWITCH
1. Ignition OFF.
2. Disconnect: Ignition Switch.
3. Carry out the ignition switch component test.
  Refer to the OEM Wiring Diagrams - COMPONENT TESTING for connector information.
Is the ignition switch OK?
1. Yes: REPAIR circuit BU/GY for an open.
2. No: INSTALL a new ignition switch. REFER to IGNITION SWITCH .
CHECK FOR CORRECT BCM OPERATION
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?
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) - WITH INTELLIGENT ACCESS (IA) , or
  
  REFER to BODY CONTROL MODULE (BCM) - WITHOUT 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.
