Seat Belt Indicator

The seat belt indicator gives an indication to the vehicle operator of the status of the driver side front seat belt. This indicator is controlled by a transistor on the instrument cluster electronic circuit board based upon cluster programming and a hard wired input from the seat belt switch in the driver side front seat belt buckle unit through the seat belt indicator driver circuit. The seat belt indicator LED receives battery current on the instrument cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or START positions. The indicator will always be off when the ignition switch is in any position except ON or START. The LED only illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn on the seat belt indicator for the following reasons: seat belt reminder function, driver side front seat belt not buckled, and actuator test.
