Pinpoint Test BC: The Safety Belt Warning Chime Does Not Operate Correctly/The Belt-Minder(R) Feature Does Not Operate Correctly
Normal Operation
The Instrument Panel Cluster (IPC) receives the safety belt and Belt-Minder(R) requests from the Restraints Control Module (RCM) over the High Speed Controller Area Network (HS-CAN). The safety belt warning chime sounds for approximately 6 seconds when the driver safety belt is not fastened and the ignition is switched from the OFF or ACC to the RUN position.
The Belt-Minder(R) feature supplements the safety belt warning function and is enabled after the safety belt warning is complete. The Belt-Minder(R) simultaneously sounds the chime and illuminates the safety belt warning lamp in the IPC once the vehicle speed has exceeded 9.7 km/h (6 mph), and remains active for 5 minutes from the time it is started.
There are 2 Belt-Minder(R) strategies that are used and implemented by the IPC as commanded by the RCM. The 2 strategies are designed to provide an increased chime tone safety belt warning indicator flash activity. Belt-Minder(R) A provides 6 one-second sequences for the first minute of the Belt-Minder(R) warning. Belt-Minder(R) B provides 6 one-second sequences of 3 chime tones in rapid succession for the remainder of the Belt-Minder(R) warning.
NOTE: Whenever the vehicle is operated using MyKey(R), the RCM enables the Belt-Minder(R).
If the Belt-Minder(R) is deactivated using an administrator key and driven using a MyKey(R) key, the MyKey(R) system overrides the deactivation of Belt-Minder(R). When MyKey(R) is in use, the driver cannot configure the Belt-Minder(R) off. Once the Belt-Minder(R) is activated, the Belt-Minder(R) continues to chime periodically (does not time out after 5 minutes) and the audio system is muted until the driver safety belt is fastened. Refer to Anti-Theft - Passive Anti-Theft System (PATS) Testing and Inspection for more information on the MyKey(R) feature.
NOTE: Make sure that the Belt-Minder(R) chime operation is verified with the vehicle moving at least 9.7 km/h (6 mph).
This pinpoint test is intended to diagnose the following:
- Safety belt warning indication concern
- Belt-Minder(R) deactivated
- Speedometer concern
- IPC
PINPOINT TEST BC: THE SAFETY BELT WARNING CHIME IS INOPERATIVE/THE BELT-MINDER(R) FEATURE DOES NOT OPERATE CORRECTLY
-------------------------------------------------
BC1 CHECK THE KEY-IN-IGNITION WARNING CHIME OPERATION
- Ignition OFF.
- Insert the key into the ignition lock cylinder.
- Open the LH front door and observe the key-in-ignition warning chime operation.
- Does the key-in-ignition warning chime operate correctly?
Yes
GO to BC2.
No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.
-------------------------------------------------
BC2 CHECK THE DRIVER SAFETY BELT BUCKLE SWITCH
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: RCM PIDs.
- Monitor the RCM driver safety belt buckle PID (SBELT_D_ST) while buckling and unbuckling the driver safety belt.
- Does the PID display BUCKLED with the safety belt buckled and UNBUCKLED with the safety belt unbuckled?
Yes
GO to BC3.
No
REFER to Supplemental Restraint System Testing and Inspection.
-------------------------------------------------
BC3 CHECK THE SAFETY BELT WARNING INDICATOR FOR CORRECT OPERATION
- Ignition ON.
- Within one minute, buckle the LH front safety belt.
- With the engine running, verify the safety belt warning indicator illuminates with the safety belt unbuckled and turns off when buckled.
- Does the safety belt warning indicator operate correctly?
Yes
GO to BC4.
No
GO to Pinpoint Test X. Pinpoint Test X: The Safety Belt Warning Indicator Is Never/Always On
-------------------------------------------------
BC4 CHECK THE SPEEDOMETER OPERATION
- Verify that the speedometer is operating correctly.
- Does the speedometer operate correctly?
Yes
GO to BC5.
No
GO to Pinpoint Test F. Pinpoint Test F: The Speedometer Is Inoperative
-------------------------------------------------
BC5 CHECK THE BELT-MINDER(R) CONFIGURATION
NOTE: Verify that an administrator key is used for this test and not a MyKey(R) programmed key. When a MyKey(R) programmed key is used, the Belt-Minder(R) is automatically turned on and cannot be disabled (if previously disabled by an administrator, the Belt-Minder(R) remains disabled when an administrator key is used).
- Verify that the Belt-Minder(R) is activated or configured on for the seating position in question. Refer to Belt-Minder(R) Deactivating/Activating Service and Repair to configure without a scan tool.
- Is the Belt-Minder(R) activated for the seating position in question?
Yes
If the Belt-Minder(R) is always on above 5 km/h (3 mph) with the safety belt unfastened, the system is operating normally.
If the Belt-Minder(R) is always on with the safety belt fastened or never on with the safety belt unfastened above 9.7 km/h (6 mph), INSTALL a new RCM. REFER to Supplemental Restraint System Service and Repair. TEST the system for normal operation.
No
ACTIVATE the Belt-Minder(R) for the seating position in question. REFER to Belt-Minder(R) Deactivating/Activating Service and Repair. TEST the system for normal operation.
