Safety Belt Warning Indicator
The instrument cluster receives the safety belt warning status from the RCM over hardwired circuitry. The safety belt switch is hardwired to the RCM. When the safety belt is fastened, the safety belt switch opens and removes the ground to the RCM and turns off the indicator. When the safety belt is unfastened, the safety belt switch closes and grounds the circuit to the RCM and the indicator illuminates.
