U0272 code meaning
Lost Communication With Seat Control Switch Module D
What U0272 means
Seat control switch module D is the fourth switch unit in this series; no manufacturer documents U0272 publicly or says which seat it belongs to. Such switches need not sit on the seat at all. On 2021–2023 Escalade, Tahoe, Suburban and Yukon with the power-folding third-row bench (RPO AS8) the folding switches are in the overhead console and command the K169 folding third-row seat module; GM later dropped their red latch indicators (PIT6041). Jeep has technicians let a Grand Wagoneer third-row seat relearn its end stops by pressing its switch twice after the vehicle has been off for two minutes (9100364). So check the seat module and its learned state as well as the switch. If switch D falls silent, the seat it serves can no longer be moved from there.

Symptoms of U0272
- Rear or folding seat does not respond to its switch
- Seat stops short of its end position
Common causes of U0272
- PossibleWiring to a switch mounted away from the seat (console, roof, trim) interrupted

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0272 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 72 | The exact fault in that area. |
What to do next
- Note U0272 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.
