  4. Verify that the seat belt retractor units are securely attached.
  5. Verify that the seat belt anchor bolts are secure.
  6. Fully extend the seat belt webbing. Verify that the seat belt webbing does not have any twists or tears.
  7. Allow the seat belt webbing to retract. Verify that the seat belt webbing returns freely and completely back into the retractor.
  8. Snap the seat belt latch plate into the buckle.
  9. Sharply tug on the seat belt latch plate and the buckle. Verify that the seat belt latch plate and the buckle remain locked when tugged.
  10. Push the button on the buckle. Verify that the seat belt latch plate releases easily from the buckle. Verify that the button returns to its original position.

Circuit/System Description

The inflatable restraint sensing and diagnostic module (SDM) sends the status of the driver and passenger seat belt switch to the instrument panel cluster (IPC) via a serial data communication message. If the seat belt is unfastened, the SDM will send a message to the IPC to illuminate the fasten safety belt indicator for 72 seconds or until the seat belt is fastened.

Front Seat Belt System Operation

CAUTIONTo help avoid personal injury from unrepaired crash damage to a restraint system, perform the seat belt check for each seat belt system. Replace the seat belt system if there is any doubt about the condition of system components.
  1. The front Seat Belt System includes a driver and\or passenger seat belt retractor and buckle.
  2. The front Seat Belt System, includes a seat belt switch in the LF and RF seat buckle which controls the fasten safety belt indicators and a tone alarm. When the LF/RF seat belt is buckled, the LF/RF door is closed, and the ignition switch is in the ON position, the following events will not occur: The tone alarm will not operate. The fasten safety belts indicator will not operate.
  3. When the LF/RF seat belt is not buckled, the LF/RF door closed, and the ignition switch is in the RUN position, the following events will occur: The tone alarm will operate for 4 to 8 seconds and then turn OFF. The fasten safety belts indicator will operate for 20 seconds, until the LF/RF seat belt is buckled. Then the fasten safety belts indicator will flash for an additional 55 seconds before turning OFF. To diagnose a failure of the fasten safety belts indicator refer to «Symptoms - Seat Belts»(ref-268085-S10469232222007101800000) .
