Fasten Safety Belt Indicator
WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) illuminates the fasten safety belt indicator when any of the following occur:
- The inflatable restraint sensing and diagnostic module (SDM) detects that the driver's seat belt is unbuckled, or the signal circuit is low. The body control module (BCM) receives the seat belt switch signal via Class 2 from the SDM. The IPC receives a Class 2 message from the BCM requesting illumination. The IPC illuminates the indicator for 20 seconds and then flashes the indicator for 55 seconds. The IPC sends a Class 2 message to the BCM indicating that the indicator is illuminated. The BCM sends a Class 2 message to the radio in order to activate an audible warning.
- The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
