Headlamps

Note. The smart junction box (SJB) must be configured before installing a new module. For additional information, refer to MODULE CONFIGURATION .

The headlamps are controlled by the SJB. The headlamp and multifunction switches are hard-wired to the SJB and are constantly monitored. The SJB processes information (such as low beam, high beam or flash-to-pass requests) from these switches and outputs the appropriate command to the headlamps (which are also hard-wired to the SJB). Fault management of the headlamps provides some headlamp functionality. In the event of a headlamp switch failure, 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.

Autolamps

The autolamps are controlled by the headlamp switch, light sensor and the SJB. When the headlamp switch is in the AUTOLAMPS ON position, the SJB monitors input from the light sensor. The SJB processes this information and outputs the appropriate command to the exterior lamps. 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.

Turn Signal and Hazard Lamps

All turn signal outputs are controlled by the SJB. The multifunction switch and the hazard lamp switch are hard-wired to the SJB. When the multifunction switch is in the LH or RH TURN position, or the hazard lamp switch is engaged, the SJB processes this information and outputs the appropriate command to the turn signal lamps. All turn signal lamps provide a lamp outage indication.

Parking, Rear or License Lamps

All parking, rear, license plate and side marker lamps are controlled by the SJB. The headlamp switch is hard-wired to the SJB. When the headlamp switch is in the HEADLAMPS ON or PARKING LAMPS ON position, the SJB processes this information and outputs the appropriate command to the parking or license plate lamps, which are hard-wired to the SJB.

Fog Lamps

The fog lamps are controlled by the headlamp switch, the SJB and the fog lamp relay. When activated, the switch sends a signal to the SJB. The SJB then activates the fog lamp relay, providing power to the fog lamps. The fog lamps will not illuminate when the high beam headlamps are on.

Reversing Lamps

The reversing lamps are controlled by the SJB and the powertrain control module (PCM). The PCM sends a message through the communication network indicating the transmission is in REVERSE. The SJB processes this information and provides voltage to the reversing lamps which are hard-wired to the SJB.

Refer to HEADLIGHTS (Montego), HEADLIGHTS (Five Hundred), or HEADLIGHTS (Freestyle) for schematic and connector information.

Principles of Operation

The smart junction box (SJB) monitors the headlamp switch position by sending multiple voltage reference signals to the headlamp switch. When the headlamp switch is in any given position, that input signal is routed to ground.

The SJB also monitors the multifunction switch for a flash-to-pass or high beam request. There are 2 voltage reference circuits which monitor this. When the multifunction switch is in the FLASH-TO-PASS or HIGH BEAM position, the voltage signal is routed to ground.

Note. The flash-to-pass feature does not require any input from the headlamp switch.

When the SJB receives an input requesting the headlamps on, the SJB supplies voltage to the low beam and high beam bulbs as necessary.

Inspection and Verification

1. Verify the customer concern.
2. Visually inspect the following for obvious signs of mechanical or electrical damage.

The smart junction box (SJB) sends a reference signal to the light sensor through circuit 1416 (YE/WH). When the headlamp switch is placed in the AUTOLAMPS ON position, the SJB monitors the ambient light conditions based on the input received from the light sensor. When the ambient light level has reached a point (determined by the internal programming of the SJB), the SJB provides voltage to the headlamps, parking and license plate lamps.

1. Before starting the fog lamp assembly adjustment: check the tire inflation. make sure there are no other loads in the vehicle other than a half tank of fuel. make sure the vehicle is on level ground. make sure the fog lamps and headlamps are clean. make sure the headlamps are operating and are correctly aimed.
2. Park the vehicle on a level surface approximately 7.6 m (25 ft) from the vertical wall or screen directly in front of it.
3. The correct visual aim for the fog lamps is with the top edge of the high-intensity zone 10 cm (4 in) below the horizontal center of the fog lamps.

Headlamp Aiming

1. The headlamp aiming procedure depends on what type of beam pattern the headlamp is equipped with. Vehicles may come equipped with visual optical left (VOL), visual optical right (VOR) or SAE only (includes sealed beam type) headlamps. To identify the headlamp beam pattern, look on the headlamp lens. Molded in small letters on the headlamp lens is 1 of the following: SAE VOL and SAE VOR and SAE
2. Once the headlamp beam pattern is identified, aim the headlamps using 1 of the following methods as applicable. Photometric aimers can aim VOL-, VOR-and SAE-type headlamps only. This is the preferred method of headlamp aiming. Visual or screen method aiming can be used to aim VOL-, VOR- and SAE-type headlamps only. Mechanical aimers cannot be used with VOR- or VOL-type headlamps. Aerodynamic lamps that can be aimed mechanically have 3 nibs molded into the lens of the lamp.

Photometric Aiming

1. For the photometric aiming procedure, refer to the appropriate photometric headlamp aimer instruction manual.

2. Park the vehicle on a level surface approximately 7.6-m (25-ft) from the vertical wall or screen directly in front of it.
3. Mark a horizontal reference line on the vertical wall or screen. Measure the center of the headlamp height to ground and record the measurement. Make a 2.4-meter (8-ft) horizontal mark (using masking tape) on the vertical wall or screen at the same distance from the ground as previously recorded.
4. Turn on the low beam headlamps to illuminate the wall or screen and open the hood.
5. On the wall or screen, locate the high intensity area of the beam pattern. Place the top edge of the high intensity zone even with the horizontal reference line.
6. In addition to the horizontal line marked in Step 3 , a pair of vertical lines must be marked at the center line of the headlamps on the wall or screen. Mark the center line of the vehicle on the wall or screen. Measure from the center of the headlamp to the center line of the vehicle. Make two 1.5-meter (5-ft) vertical marks (using masking tape) on the wall or screen at the same distance from the vehicle center line as previously recorded.
7. On the wall or screen, locate the high intensity area of the beam pattern. Place the left edge of the high intensity zone even with the vertical line corresponding to the headlamp being adjusted.
8. Identify at the top edge of this high intensity area a distinct horizontal cutoff in the beam pattern. If the top edge of this cutoff is not even with the horizontal reference line, the headlamp beam needs to be adjusted.
9. For VOL-type headlamps, there is a distinct cutoff in the left portion of the beam pattern. The edge of this cutoff should be positioned 50.2 mm (2 in) below the horizontal reference line. Horizontal reference line. Top edge of the beam pattern. High intensity zone.
