- Inspect the shoulder belt guide in order to ensure that the following conditions are met: The shoulder belt guide swivels freely in the rear seat position. The seat belt webbing is seated flatly in the guide slot. The seat belt webbing does not bind.
- Verify that the seat belt buckle faces inboard and is accessible.
- Verify that the seat belt retractor units are securely attached.
- Verify that the seat belt anchor bolts are secure.
- Fully extend the seat belt webbing. Verify that the seat belt webbing does not have any twists or tears.

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.
