signal circuit.
The following actions will occur if there is an open or a short to ground in the ambient light sensor circuit:
-
The scan tool will display DARK.
-
The BCM will default into a DARK state and turn the headlamps ON.
If the head lamps are set to the AUTO position while in the LIGHT state and the ambient light level conditions change to DARK for 15 seconds, the
BCM will turn the headlamps ON.
If the headlamps are set to the AUTO position while the DARK state and the ambient light level conditions change to LIGHT for 20 seconds, the BCM
will turn the headlamps OFF.
Dusk
YES/NO
The displayed value refers to the dimming signal output from the BCM.This information is used by the BCM for the operation of the following features:
-
Automatic headlamp
-
Daytime running lamps (DRL) feature
Dusk is displayed whenever the park lamps are ON.
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.
Vehicle Speed
Range: 0 - 205 km/h (0 - 127 mph)

following components for 20 minutes after the ignition key is turned to the OFF position and before any door is opened:
-
The radio
-
The power windows
When any door is opened or after 20 minutes, the BCM opens the ground circuit for the RAP relay. The following components will turn OFF:
