| 09-011-26 | 2026-03-03. Service bulletin. EXTERIOR LIGHTING. This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 09-019/25 04/15/25 Some vehicles equipped with the Adaptive Front lighting System (AFS) may exhibit the exterior light warning light/exterior light warning indication on while driving or when the ignition is turned on and DTC B10A3:86 (Error signal received from swivel actuator (LH)) stored in memory. NOTE: The combination light with AFS can be distinguished if it is equipped with the parking light/daytime running light (DRL) that illuminates while the ignition is turned on. This may be caused by the AFS Control Module detecting a false headlight malfunction. This concern will likely occur when the light returns to the center position after swiveling. To eliminate this concern, the control software of the AFS control module has been further modified. |
