U02BD code meaning
Lost Communication With Night Vision Control Module
What U02BD means
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.
U02BD at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U02BD
- 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
Common causes of U02BD
- Most likelyMisaligned or not fully seated terminals in the module connector
- PossibleBent pins on the night vision module
- Less likelyModule supply missing or module internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U02BD means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| BD | The exact fault in that area. |
What to do next
- Note U02BD 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.
Questions about U02BD
What does U02BD mean?
U02BD means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with U02BD?
U02BD does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U02BD fail an emissions test?
U02BD is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U02BD to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will U02BD clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
