This is how a professional tech would solve this problem.

View a factory wiring diagram an test electrical circuits with a DVOM - digital volt ohmmeter.

If the park brake is applied after the ignition key is placed in the RUN position the ALC is not effected If the park brake is applied after the ignition key is placed in the RUN position the ALC is not effected Also knowing how they work is a good thing. Locate the dimmer switch for your lights. Put the key in the ignition and turn it to the 'on' or 'accessory' position.

The ignition switch is in the RUN position. You don’t need to start your car, but you do need power running to the lights.

The conditions necessary for the BCM to activate the ACL mode are as follows: In response, the BCM grounds only the park lamp relay control circuit, and the lamps illuminate as stated above.

The BCM always turns ON the park lamps and headlamps together when in the ALC mode.įor manual operation, when the headlamp switch is in the PARK position, the headlamp switch supplies ground to the BCM on the park lamp switch signal circuit. The now closed relay supplies voltage on the park lamp supply voltage circuit directly to the lamps. Under low light conditions the BCM grounds the park lamp relay control circuit energizing the park lamp relay. The BCM controls the park lamp relay by grounding the park lamp control circuit energizing the relay.įor automatic lamp control (ALC) the BCM receives a signal from the ambient light sensor indicating a low or high ambient (outside) light level. The PARK fuse in the fuse block - instrument panel (I/P) supplies voltage to both the coil and switch input side of the park lamp relay. These lamps are illuminated any time the headlamp switch is in the PARK, ON position, or anytime the body control module (BCM) illuminates the headlamps.

The park lamps consist of the park, tail, marker and license lamps. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch. When the headlight switch is turned to the park lamp or headlamp position, all incandescent back lighting turn ON at the dimming level indicated by the I/P dimmer switch. All the VF and incandescent back lighting lamps are provided a specific voltage and are then grounded. The BCM then sends a pulse width modulation (PWM) voltage to all the interior lamps. The setting of the I/P dimmer switch determines the amount of voltage that the I/P dimmer switch supplies to the BCM through the I/P dimming lamps low reference circuit. The BCM then supplies voltage to the I/P dimmer switch through the I/P dimming lamps control circuit. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). At the same time all VF displays dim to match the indicated dimming level. When the park lamps are ON, all incandescent back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch.

When the ignition switch is turned to the ON position, the VF display, radio, turns ON at maximum brightness.

The PRNDL lamp, with the exception of the current gear select position.

This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps. Also knowing how they work is a good thing.
