U0222 code meaning
Lost Communication With Door Window Motor A
What U0222 means
U0222 says door window motor A, a motor with its own electronics, is no longer heard. GM uses it on 2021–2025 Escalade, Tahoe, Suburban and Yukon with air leveling (RPO F47): PIT5981B lists U0222 to U0225 as codes that can sit beside a low or leaning air suspension, a Service Leveling System message or short-term inflates that do nothing. The link is the door-ajar switch, wired directly to each window motor; while a motor is silent, the door state is unknown and the scan tool shows closed by default. GM saw this mostly on upfitted vehicles such as armored cars or limousines. On its 2014–2018 trucks GM still used its own U1534 for the driver window motor. No MIL.

What each part of U0222 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 22 | The exact fault in that area. |
What to do next
- Note U0222 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.
