U02BDLost Communication With Night Vision Control Module
- Generic OBD-II code · Network
- How the car detects it
- The night vision control module evaluates an infrared camera, either a passive thermal unit that sees body heat or an active near-infrared system, picks out pedestrians and animals and passes image and warnings to the cluster or head-up display. U02BD is stored when a listening module, usually the body controller, hears nothing more from it. Jeep documents the case for the 2021-2023 Grand Cherokee including the 4xe (STAR S2208000163): the BCM holds U02BD-00, the cluster logs B0125-02 for the night vision module, and the system stays dark. Causes were female terminals in harness connector D3944A that were misaligned or held back by a solder spot, so the module's pins bent or never made contact. Realigning terminals or a connector kit cures it; the module is replaced only for lasting pin damage. Driving is unaffected.
