Start/Stop Switch

The start/stop switch is a momentary dual contact switch that is hardwired to the BCM and the PCM.

Both sets of contacts are normally open and receive voltage at all times. When the start/stop switch is pressed, one set of contacts supplies voltage to the BCM only. The second set of contacts supply voltage to the BCM, RFA module and the PCM.

The start/stop switch has an LED, that is used for switch illumination.
