B0125 concerns the night vision control module, which processes the camera image and passes it to the display. Stellantis uses this code: on the 2023 Jeep Grand Cherokee the cluster stores B0125-02, Night Vision Control Module general signal failure, alongside U02BD (lost communication) in the BCM. Case S2208000163 blames misaligned or not fully seated terminals at connector D3944A of the processing module; case S2408000119 adds B14FB-31 (no video signal) in that module and names a cracked camera lens as one cause. GM's PIT5785 for Cadillac XT5 and XT6 shows the same link from the cluster end: an unplugged black LVDS connector there leaves a green pixelated picture. Night vision is lost; driving is not affected.

Likely causes

Misaligned, bent or not fully seated terminals at the module connector

Video link (LVDS) to the cluster loose or damaged

Camera delivers no usable image, e.g. cracked lens
