Connector “A” (Figure 2, A) can be
seated but not fully engaged. When
pushing on this connector the projector
will swivel, thus you will need 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 510 degrees off center. Thus, please
check to ensure 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. Take care
when wiggling this connector because if
it becomes fully disconnected, it is very
difficult and 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 then 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 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 but also 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 at speed 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.
