B0125 code meaning
Night Vision Control Module
What B0125 means
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.

Symptoms of B0125
- Night vision unavailable message in the cluster
- No, frozen or pixelated night vision image
Common causes of B0125

What each part of B0125 means

| 25 | The exact fault in that area. |
What to do next
- Note B0125 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
