U053C code meaning
Invalid Data Received From Image Processing Module B
What U053C means
U053C is documented by GM on cars with Super Cruise. On the 2023 Cadillac Lyriq it could set at start-up and remain current for as long as half an hour, keeping Super Cruise unavailable; an ignition cycle cleared it in some cases only (PIC6500). Revision PIC6500A widened the list of codes stored by that module and told technicians not to replace the controller, and PIC6500B closed the case in 2024. For the 2026 range from Escalade and Tahoe to Lyriq, Vistiq and Sierra EV, PIC6607 through PIC6607B again state that a history U053C is unrelated to the real Super Cruise fault and must not lead to module replacement. Elsewhere module B is often a surround-view unit, as Ford's IPMB on Explorer and Aviator. Lost communication is U023B.
U053C at a glance
- 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 U053C
- Super Cruise Unavailable message
- Adaptive cruise or Service Driver Assist message
- Surround view camera display faulty (other makes)
Common causes of U053C
- Most likelySoftware behaviour at start-up between the image processing modules (GM Super Cruise)
- PossibleStored history code unrelated to the actual fault (GM PIC6607)
- Less likelyFault in module B or its network connection
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

Image processing module b
What each part of U053C means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3C | The exact fault in that area. |
What to do next
- Note U053C 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 U053C
What does U053C mean?
U053C means "Invalid Data Received From Image Processing Module B". U053C is documented by GM on cars with Super Cruise. It is a generic code, so it means the same on every make.
Is it safe to drive with U053C?
U053C does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U053C fail an emissions test?
U053C 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 U053C to fix?
Difficulty: medium. A typical repair takes 0.2 to 2 hours of work. This is a job for a workshop.
Will U053C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
