U0504Invalid Data Received From Door Control Module E
- Generic OBD-II code · Network
- How the car detects it
- U0504 is the one door code of this series with a public manufacturer case. Ford names the electronic door latch controllers DCME to DCMH, and its programming applications list DCME as door control module E. In 2024–2026 Lincoln Nautilus and 2025–2027 Aviator, latch software stored B1262:92 in several of these modules, and U0504 could appear in the gearshift module, which evidently uses door status. The cluster then warned of a door fault, of the transmission not being in Park or of hill start assist being unavailable; the fix was a software update of DCME–DCMH (SSM 54938, 54978, 55241). No check engine light is mentioned. In GM's Saab 9-5 list the lost-communication partner U0203 is the left rear door switch panel.
