Original publication
Only vehicles with Xenon headlights can be affected by this condition.
The customer complains the high beams do not function on one side or one of the low beams flickers
intermittently. In addition to this, an “Adaptive Headlight Defective” warning can be present in the cluster
if the vehicle has the Prestige trim level.
One of the following DTCs are set in the vehicle electrical system control module, J519 (09), or in the
headlamp range control module, J431 (55), depending on the trim level of the vehicle. Vehicles with the
Premium Plus option package can have the DTC set in the J519 (09) module. Vehicles with the Prestige
option package can have the DTC set in the J431 (55) module.

Service
1. Verify which side is affected based on the DTC or customer complaint and remove the affected
headlamp per the instructions listed in the ElsaWeb Repair Manual: Repair Manual>>Electrical
System>>94 Exterior Lights, Switches>>Removal Installation>>HID Headlamp, From MY 10
2. Remove the covers from the back of the headlamp housing.
3. Physically check all the connectors
inside the headlamp housing for
proper seating and visually inspect
the locks to ensure they are fully
engaged (Figure 1).

Connector “A” (Figure 2, A) can be
seated but not fully engaged. When
pushing on this connector the
projector will swivel, so it is
important to hold the projector
housing when applying pressure to
the connector.
Figure 2. Connector “A” shown not fully seated.
Connector “B” (Figure 3, B) can be
fully locked into place but it can be
rotated 5-10 degrees off
center. Therefore, it is important to
ensure that the harness connector is
seated parallel to the connector
housing on the headlamp.

Technical Service Bulletin
Connector “C” (Figure 4, C) is located
behind the motor mechanism, which
rests below the projector lens. This is
a very small two-pin connector. Use
caution when wiggling this connector
because if it becomes fully
disconnected, it is almost impossible
to reconnect without using special
tools. Place your finger, or a set of
small bent pliers, on this connector
and pull towards yourself to fully
seat the connector.
Figure 4. Connector “C” shown in the locked position.
4. Ensure all the connectors are fully seated and locked. If a loose connector is found, skip step 5 and
move to step 6.
5. If no loose connector is found, and the issue still persists, the issue is outside the scope of this TSB
and the remaining steps can be skipped. A swap of headlamp components between left and right is
the next logical step to narrow down the failed part of the headlamp.
6. Reassemble the headlamp and install it back in to the vehicle.
7. Clear the DTC(s) and retest with low beams activated, high beams activated, and all turn signals
activated.
8. If no DTCs return, test the headlamp functionality in the garage or parking lot. In addition, perform
a short road test and repeat the actuation of all headlamps functions while at a speed. To test the
adaptive light function (if equipped), the vehicle will need to be driven around a corner at a speed
greater than 6mph.
Note:
It may be difficult to use the high beams while in traffic; therefore, please use caution and do not
create an unsafe condition for you and your fellow drivers.
