MODELS WITH EYESIGHT ONLY. This bulletin provides a repair procedure to address DTC B2902 which may be stored erroneously due to a specification mismatch. This bulletin applies to a very limited number of early-production 2017 model year vehicles without the auto headlamp leveling (AHL) feature only. Having the incorrect control module installed has absolutely NO effect on normal headlamp system operation and does not cause any warning lamp(s) to illuminate. The repair involves replacing the headlamp control module.
