Pinpoint Test B: The Key-In-Ignition Warning Chime Is Inoperative
- B1 RETRIEVE THE RECORDED SJB DTCS FROM BOTH THE CONTINUOUS AND ON-DEMAND SJB SELF-TESTS
- Check for recorded SJB DTCs from the continuous and on-demand self-tests.
- Is SJB DTC B1352 recorded?
Yes : GO to B4.
No : GO to B2.
- B2 CARRY OUT THE INSTRUMENT CLUSTER WARNING LAMPS AND CHIME ACTIVE COMMAND USING THE DIAGNOSTIC TOOL
- Connect the scan tool.
- Key in ON position.
- Enter the following diagnostic mode on the scan tool: Instrument Cluster Active Command Self-Test.
- Select the instrument cluster warning lamps and chime active command. Trigger the chime active command.
- Does the chime sound?
Yes : GO to B3.
No : GO to B6.
- B3 CHECK THE INTERIOR LAMPS
- Open the driver door.
- Does the interior lamp illuminate when the driver door is open?
Yes : GO to B4.
No : REFER to INTERIOR LIGHTING to continue diagnosis of the interior lamps.
- B4 CHECK CIRCUIT 158 (BK/PK) FOR AN OPEN OR SHORT TO GROUND
- Remove the ignition key from the ignition switch.
- Disconnect: Ignition Switch C250.
- Disconnect: SJB C2280e.
- Measure the resistance between the SJB C2280e-29, circuit 158 (BK/PK), harness side and the ignition switch C250-5, circuit 158 (BK/PK), harness side; and between the SJB C2280e-29, circuit 158 (BK/PK), harness side and ground.
- Is the resistance less than 5 ohms between the SJB and the ignition switch, and greater than 10,000 ohms between the SJB and ground?
Yes : GO to B5.
No : REPAIR the circuit. TEST the system for normal operation.
- B5 CHECK THE IGNITION SWITCH
- Insert the ignition key into the ignition switch.
- Measure the resistance between the ignition switch C250-5, component side and C250-4, component side; and between the ignition switch C250-5, component side and ground.
- Is the resistance less than 5 ohms between the ignition switch pins, and greater than 10,000 ohms between the ignition switch and ground?
Yes : GO to B6.
No : INSTALL a new ignition switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
- B6 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. CLEAR the DTCs. REPEAT the self-test.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
