U02BD Lost Communication With Night Vision Control Module

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.

Likely causes

Misaligned or not fully seated terminals in the module connector
Bent pins on the night vision module
Module supply missing or module internally faulty

Symptoms

  • Night vision display stays dark or the function is unavailable
  • Pedestrian or animal warnings at night are missing
  • Matching night vision code stored in the instrument cluster
