High Beam Input




Range: 0.0-18.0 Volts
The BCM uses this input in order to determine the state of the high beam headlamps. The BCM measures the circuit voltage at a point between both of the high beam headlamps and the beam selector switch. The high beam input voltage will vary depending on the state of the headlamps. Refer to the table.
