U053B code meaning
Invalid Data Received From Image Processing Module A
What U053B means
Image processing modules evaluate camera data for assistance functions, and module A is the one most often named in service literature. GM's 2025 brake controller tables (25OBDG04A) check protection values and rolling counters in messages from the object fusion controller (EOCM); 3 errors in a window of 16 frames set U053B as Type C without MIL, and the test pauses outside 9 to 16 V. Ford's OBD summaries let the PCM store it, non-MIL, on Remote Park Assist and Auto Hitch programs. On the 2025 Maverick, IPMA software caused U053B:56 in the cluster (SSM 53385, update per SSM 54423). The 2025 Jeep Compass logs U053B 81 after a 12 V disconnect until the steering angle is relearned. GM's Lyriq bulletin PIC6500A lists it among codes held by the Lyriq camera processor. Lost communication is U023A.

- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.2 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U053B
- Lane keeping or adaptive cruise unavailable message
- Remote park assist or automatic hitch function refused
- Code stored without noticeable symptoms
Common causes of U053B
- Most likelySoftware in image processing module A (update available, e.g. Ford Maverick)
- PossibleSteering angle not relearned after battery disconnect or transport mode (Jeep Compass)
- PossibleFront camera not calibrated after windshield or module replacement
- Less likelySupply voltage outside the valid window during start-up
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U053B means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3B | The exact fault in that area. |
What to do next
- Note U053B 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 U053B
What does U053B mean?
U053B means "Invalid Data Received From Image Processing Module A". Image processing modules evaluate camera data for assistance functions, and module A is the one most often named in service literature. It is a generic code, so it means the same on every make.
Is it safe to drive with U053B?
U053B does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U053B fail an emissions test?
U053B 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 U053B to fix?
Difficulty: medium. A typical repair takes 0.2 to 2 hours of work. This is a job for a workshop.
Will U053B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
