Pinpoint Test AJ: The Chime Sounds When The Driver Door Is Ajar (No Key In Ignition And Headlamps Off)
Refer to Wiring Diagram Set 60, Instrument Cluster for schematic and connector information. Diagrams By Number
Normal Operation
The Instrument Panel Cluster (IPC) receives the key-in-ignition warning status from the Smart Junction Box (SJB) over the Medium Speed Controller Area Network (MS-CAN) communication bus.
On vehicles without Intelligent Access (IA), the key-in-ignition warning switch (part of the ignition switch) is hardwired to the SJB (Smart Junction Box) through the key-in-ignition input circuit. When the key is inserted into the ignition lock cylinder, the key-in-ignition switch closes and supplies voltage to the SJB (Smart Junction Box).
On vehicles with IA (Intelligent Access), the SJB (Smart Junction Box) receives the key-in-ignition status from the Remote Function Actuator (RFA) module through the key-in-ignition input circuit. When the ignition is placed in the ACC position or if the vehicle is turned off with the selector lever out of PARK (P), the RFA (Remote Function Actuator) module provides voltage to the SJB (Smart Junction Box) through the key-in-ignition input circuit.
The SJB (Smart Junction Box) monitors the door ajar input from the LH front door and the key-in-ignition switch status. When the SJB (Smart Junction Box) detects a key-in-ignition voltage and the LH front door is open or ajar, the SJB (Smart Junction Box) sends the IPC (Instrument Panel Cluster) a chime request message to sound the key-in-ignition warning chime.
- DTC B1217:15 (Passive Key-In-Ignition Output: Circuit Short to Battery or Open)- an on-demand DTC that sets in the RFA (Remote Function Actuator) module when the RFA (Remote Function Actuator) module detects an open or short to voltage on the key-in-ignition output circuit.
- DTC B1352 (Ignition Key-In Circuit Failure)- an on-demand DTC that sets in the SJB (Smart Junction Box) if the SJB (Smart Junction Box) detects an open on the key-in-ignition switch input circuit or if the SJB (Smart Junction Box) detects ignition START, RUN/START or RUN/ACC inputs without the key-in-ignition input.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Key-in-ignition warning switch (part of the ignition switch) (without IA (Intelligent Access))
- RFA (Remote Function Actuator) module (with IA (Intelligent Access))
- SJB (Smart Junction Box)
PINPOINT TEST AJ : THE CHIME SOUNDS WHEN THE DRIVER DOOR IS AJAR (NO KEY IN IGNITION AND HEADLAMPS OFF)
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Verify that the SHIFT TO PARK message is not displayed in the message center before proceeding with diagnostics.
AJ1 CHECK THE IPC (Instrument Panel Cluster) ILLUMINATION
- Verify the IPC (Instrument Panel Cluster) is not illuminated with the headlamp switch off.
Does the IPC (Instrument Panel Cluster) illumination operate correctly?
Yes
GO to AJ2.
No
REFER to Instrument Panel, Gauges and Warning Indicators.
AJ2 RETRIEVE THE RECORDED DTCs FROM THE SJB (Smart Junction Box) SELF-TEST
- Check for recorded DTCs from the SJB (Smart Junction Box) self-test.
Is DTC B1352 present?
Yes
If equipped with IA (Intelligent Access), GO to AJ3.
If equipped without IA (Intelligent Access), GO to AJ4.
No
GO to AJ5.
AJ3 RETRIEVE THE RECORDED DTCs FROM THE RFA (Remote Function Actuator) MODULE SELF-TEST
- Check for recorded DTCs from the RFA (Remote Function Actuator) module self-test.
Is DTC P1217:15 present?
Yes
GO to AJ5.
No
GO to AJ4.
AJ4 CHECK THE SJB (Smart Junction Box) IGNITION INPUT PIDs
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: SJB (Smart Junction Box) DataLogger.
- Select and monitor the SJB (Smart Junction Box) PIDs ignition ACC (IGN_A_ECU), ignition OFF (IGN_O_ECU), ignition RUN (IGN_R_ECU), and ignition START (IGN_S_ECU) while cycling the ignition from ACC, OFF, RUN and START.
Do the SJB (Smart Junction Box) PIDs match the ignition mode?
Yes
INSTALL a new SJB (Smart Junction Box). TEST the system for normal operation.
No
REFER to Steering Column to diagnose the ignition outputs to the SJB (Smart Junction Box).
AJ5 CHECK THE SJB (Smart Junction Box) KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE
- Ignition OFF.
- Disconnect: SJB (Smart Junction Box) C2280B.
- Measure the voltage between the SJB (Smart Junction Box) C2280B-35, circuit CDC30 (BU/GY), harness side and ground.
Is any voltage present?
Yes
GO to AJ6.
No
GO to AJ7.
AJ6 CHECK THE SJB (Smart Junction Box) KEY-IN-IGNITION INPUT CIRCUIT FOR A SHORT TO VOLTAGE
- Disconnect: Ignition Switch C250 (Without IA (Intelligent Access)) or RFA (Remote Function Actuator) Module C2153D (With IA (Intelligent Access)).
- Measure the voltage between the SJB (Smart Junction Box) C2280B-35, circuit CDC30 (BU/GY), harness side and ground.
Is any voltage present?
Yes
REPAIR circuit CDC30 (BU/GY) for a short to voltage. TEST the system for normal operation.
No
If not equipped with IA (Intelligent Access), INSTALL a new ignition switch. TEST the system for normal operation.
If equipped with IA (Intelligent Access), GO to AJ8.
AJ7 CHECK FOR CORRECT SJB (Smart Junction Box) OPERATION
- Disconnect all the SJB (Smart Junction Box) connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the SJB (Smart Junction Box) connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new SJB (Smart Junction Box). 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.
AJ8 CHECK FOR CORRECT RFA (Remote Function Actuator) OPERATION
- Disconnect all the RFA (Remote Function Actuator) connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the RFA (Remote Function Actuator) connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new RFA (Remote Function Actuator) module. 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.
