Pinpoint Test A: The Key-In-Ignition Warning Chime Is Inoperative
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
- A1 CHECK THE RECORDED INSTRUMENT CLUSTER DTCS FROM BOTH THE CONTINUOUS AND ON-DEMAND SJB SELF-TESTS
- Check the recorded instrument cluster DTCs from the continuous and on-demand self-tests.
- Is DTC B1352 recorded?
Yes : GO to A4.
No : GO to A2.
- A2 CARRY OUT THE INSTRUMENT CLUSTER WARNING LAMPS AND CHIME ACTIVE COMMAND
- Connect the diagnostic tool.
- Key in ON position.
- Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
- Select the instrument cluster warning lamps and chime active command. Trigger the chime active command.
- Does the chime sound?
Yes : GO to A3.
No : GO to A5.
- A3 CHECK THE DOOR AJAR INDICATOR
- Key in OFF position.
- Disconnect the diagnostic tool.
- Make sure all the doors are closed.
- Key in ON position.
- While observing the message center (if equipped) or the door ajar warning indicator, open the driver door.
- Is the DRIVER DOOR AJAR message displayed on the message center (if equipped) or the door ajar warning indicator illuminated with the driver door open?
Yes : GO to A5.
No : If not equipped with a message center, REFER to INSTRUMENT CLUSTER to continue diagnosis of the door ajar warning indicator. If equipped with a message center, REFER to INFORMATION AND MESSAGE CENTER to continue diagnosis of the message center.
- A4 CHECK CIRCUIT CDC30 (BU/GY) FOR AN OPEN OR A SHORT TO GROUND
- Key in OFF position.
- Disconnect: Instrument Cluster C220.
- Disconnect: Ignition Switch C250.
- Measure the resistance between the instrument cluster C220-7, circuit CDC30 (BU/GY), harness side and the ignition switch C250-5, circuit CDC30 (BU/GY), harness side; and between the instrument cluster C220-7, circuit CDC30 (BU/GY), harness side and ground.
- Is the resistance less than 5 ohms between the instrument cluster and the ignition switch, and greater than 10,000 ohms between the instrument cluster and ground?
Yes : INSTALL a new ignition switch. REFER to STEERING COLUMN SWITCHES . CLEAR the DTCs. REPEAT the self-test.
No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- A5 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Disconnect the instrument cluster connector.
- Check for:
- Corrosion
- Pushed-out pins
- Connect the instrument cluster connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes : INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . TEST the system for normal operation.
No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
