B0124 points at the night vision camera, usually a far-infrared thermal sensor behind the grille or in the bumper; Teledyne FLIR says it has supplied more than a million automotive thermal sensors. Its exposed position causes most faults. GM's PIC6352A for Cadillac CT6, XT5 and XT6 traces failed camera learn procedures to loose or corroded LVDS connectors between camera B276 and its control module, often after water entered a damaged camera. Bentley's 2055858/1 for the Bentayga describes stone chips letting water in and corroding the camera cable, and Stellantis case S2408000119 warns that a cracked lens distorts the picture. None of these bulletins quotes B0124 itself. Night vision stops working; normal driving is unaffected.
