Pinpoint Test Am: The Key-In-Ignition Warning Chime Is Inoperative
- AM1 CHECK THE SAFETY BELT WARNING CHIME OPERATION
- Ignition OFF.
- Unbuckle the driver safety belt.
- Ignition ON.
- 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?
- Yes : GO to AM2.
- No : INSTALL a new IPC. REFER to INSTRUMENT PANEL CLUSTER (IPC) .
- AM2 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 AM3.
- No : REFER to INTERIOR LIGHTING .
- AM3 RETRIEVE THE RECORDED DTCs FROM THE BCM SELF-TEST
- Ignition ON.
- Using a scan tool, perform the BCM self-test.
- Are any DTCs present?
- Yes
: For DTC B10F1:13, GO to AM4.
For all other DTCs, REFER to MULTIFUNCTION ELECTRONIC MODULES .
- No : GO to AM6.
- AM4 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE AT THE BCM
- Ignition OFF.
- Insert the key into the ignition cylinder.
- Disconnect: BCM C2280C.
- Measure the voltage
between:
Positive Lead Negative Lead Pin Circuit Pin Circuit C2280C-46 CDC30 (BU/GY) - Ground - Is the voltage greater than 11 volts?
- Yes : GO to AM6.
- No : GO to AM5.
- AM5 CHECK THE IGNITION SWITCH
- Ignition OFF.
- Disconnect: Ignition Switch.
- Carry out the ignition switch component test. Refer to the OEM WIRING DIAGRAM COMPONENT TESTING article.
- Is the ignition switch OK?
- Yes : REPAIR the key-in-ignition input circuit.
- No : INSTALL a new ignition switch. REFER to STEERING COLUMN SWITCHES .
- AM6 CHECK FOR CORRECT BCM OPERATION
- Disconnect and inspect all the BCM connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect all the BCM connectors. Make sure they seat and latch correctly.
- 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 MULTIFUNCTION ELECTRONIC MODULES .
- 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.
