U0272Lost Communication With Seat Control Switch Module D
- Generic OBD-II code · Network
- How the car detects it
- 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.
