Fasten Safety Belt Indicator
WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The fasten safety belt indicator may only be illuminated during RUN. The instrument panel cluster (IPC) illuminates the fasten safety belt indicator under the following conditions:
- During bulb check.
- The inflatable restraint sensing and diagnostic module (SDM) sends the status of the driver's seat belt switch to the IPC via a class 2 message. If the driver's seat belt is unfastened, the IPC will illuminate the fasten safety belt indicator for 72 seconds or until the driver's seat belt is fastened. If the driver's seat belt is unfastened within 8 seconds following the bulb check, the IPC will send a class 2 serial message requesting 5 chimes to sound.
