Exterior Lighting

EXTERIOR LIGHTING

NOTE: The smart junction box (SJB) must be configured before installing a new one.

The exterior lighting outputs are controlled by the SJB. An additional function of the lighting system is a lamp outage function which indicates to the driver if certain exterior bulbs are not functioning. If there is an inoperative bulb, the SJB sends a message to the instrument cluster indicating that the lamp is inoperative.

In the event of all multifunction switch, all headlamp switch or ignition switch invalid or missing data failures, the exterior lamps are illuminated. There is also a headlamp battery saver feature. This feature turns off the headlamps 10 minutes after the ignition switch is turned off.

Autolamps and daytime running lamps (DRL) are 2 functions which may be configured in the SJB.

The autolamps are controlled by the headlamp switch, light sensor and the SJB. When the headlamp switch is in the AUTOLAMP position, the SJB monitors input from the light sensor. The autolamps remain ON for a preselected amount of time (approximately 20 seconds to 3 minutes depending on customer preferences) after the ignition switch is changed from the ON position to the ACC or OFF position.

The exit time delay is programmed in the following sequence.

NOTE: Steps 2 through 5 must be carried out within a 10 second period.

1. Make sure the ignition switch is turned OFF and the headlamp switch is in the autolamps ON position.
2. Place the headlamp switch to the OFF position.
3. Turn the ignition switch to the RUN position.
4. Turn the ignition switch to the OFF position.
5. Place the headlamp switch to the autolamps ON position (at this time the headlamps and parking lamps illuminate).
6. When the desired length of time is reached (maximum of 3 minutes), place the headlamp switch to the OFF position.
