Seat Belt System Circuit Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

There are two fasten safety belt indicators for this vehicle. The driver fasten safety belt indicator is located on the instrument panel cluster (IPC) and the passenger fasten safety belt indicator is located near the center of the instrument panel (I/P). Both indicators are controlled by the IPC at the request of the inflatable restraint sensing and diagnostic module (SDM). The driver and passenger indicators when initiated will illuminate for 20 seconds followed by 55 seconds of flashing. Audible warnings will initiate simultaneously with visual warnings and last for 8 seconds. Subsequently, similar events will occur until the seat belts are buckled or the ignition is returned to the OFF position.

The driver fasten safety belt indicator will illuminate when any of the following occur:

The driver seat belt is unbuckled while the ignition is ON.
The driver seat belt remains unbuckled and vehicle speed is greater than 8 km/h (5 mph).
Three minutes after previous seat belt status reminder event
The IPC performs the displays test at the start of each ignition cycle.

IMPORTANT: The front passenger seat is equipped with a passenger presence system (PPS), which detects an occupant. If the PPS detects an empty front passenger seat, then the passenger fasten safety belt indicator will be disabled.

The passenger fasten safety belt indicator will illuminate when any of the following occur:

Twenty-five seconds after the ignition is ON and the front passenger seat belt remains unbuckled with passenger present
The front passenger seat belt remains unbuckled with passenger present and vehicle speed is greater than 5 mph (8 km/h).
Three minutes after previous seat belt status reminder event
The IPC performs the displays test at the start of each ignition cycle.
