Seat control module C usually serves a seat beyond the two front ones. GM's Saab 9-5 code list assigns the partner slot U0210 to the rear seat heating control module, and Ford labels its rear seat electronics with later letters altogether (SCMK and SCML for the second-row power seats of the 2025 Navigator, SCMJ for the third-row fold module), so module C is anything but uniform. U0511 is stored when frames from module C reach the network but their content is rejected. No public document names U0511. Rear seat modules often sit under carpets or folding mechanisms where harnesses get pinched, a cause more typical here than at the front. Effects: rear seat heating, folding or adjustment unavailable.

Likely causes

Harness pinched by rear seat folding or rail mechanism
Configuration of the rear seat module missing after replacement
Seat control module C internally faulty

Symptoms

  • Rear seat heating not switching on
  • Power folding or adjustment of a rear seat inoperative
