Ignition Input

The ignition input is used to turn the BCM on. When the BCM is turned on, it will read the resistor and control the outputs accordingly. When the BCM is turned off the resistor is not read, and the theft deterrent relay and fuel enable output will not allow the engine to start. When the ignition switch is in the 'OFF" position, the battery input to the BCM will draw about 75 milli-amps for the first 10 minutes and about 2.4 milli-amps after 10 minutes of ignition off.
