Pinpoint Test BG : The Key-In-Ignition Warning Chime Is Inoperative
- BG1 CHECK THE SAFETY BELT WARNING CHIME OPERATION
- Ignition OFF.
- Ignition ON.
- Monitor the safety belt warning chime when the ignition switch is transitioned from OFF to RUN for 6 seconds.
Does the safety belt warning chime operate for approximately 6 seconds?
Yes GO to BG2 No IPC Guided Routine Testing - BG2 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 BG3 No REFER to: Interior Lighting . - BG3 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 BG4 - BG4 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 BG5 No GO to BG9 - BG5 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE
- Ignition OFF.
- Insert the key into the ignition cylinder.
- Disconnect BCM C2280G.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280G-38 Ground
Is the voltage greater than 11 volts?
Yes GO to BG9 No GO to BG6 - BG6 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR SHORT TO GROUND
- Remove the key from the ignition cylinder.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280G-38 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to BG7 No REPAIR the circuit. - BG7 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR OPEN
- Disconnect Ignition Switch C250.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280G-38 C250-5
Is the resistance less than 3 ohms?
Yes GO to BG8 No REPAIR the circuit. - BG8 CHECK THE IGNITION SWITCH
- Remove the ignition switch. REFER to: Ignition Switch .
- Perform the ignition switch component test. Refer to Component Testing for schematic and connector information.
Is the ignition switch OK?
Yes INSTALL a new ignition lock cylinder housing. REFER to: Ignition Lock Cylinder Housing . No INSTALL a new ignition switch. REFER to: Steering Column Multifunction Switch LH . - BG9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the BCM and all related in-line 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 and all related in-line 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) 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.
