TECHNICAL SERVICE BULLETIN: MULTI-FUNCTION SWITCH REPLACEMENT (SC130) - This bulletin provides the procedure to replace the Multi-Function Switch (see below) in certain 2015~2016MY K900 (KH) Luxury V8 vehicles, equipped with LED Headlights, and produced from December 18, 2013 through January 11, 2016. Use of the headlights in AUTO mode over time may result in increased electrical resistance of the contact points, which in turn may affect the operation of the Electronic Control Unit located inside the Multi-Function Switch. If this occurs, the headlights may flicker and/or intermittently turn off while driving. To correct this condition, follow the procedure outlined in this bulletin. Before conducting the procedure, verify the vehicle is included in the list of affected VINs.
