Switch module B is a second, separate seat switch unit, for the passenger side or another seat row; which position B denotes is not published by any manufacturer. Mercedes counts its seat switch groups by position, front left being SSE-VL, which points to one unit per seat. Lincoln shows the 2nd-row case: on 2025 Navigators with power second-row seats the switch would not move the seat fore and aft, with B167F:11 in the rear seat modules SCMK/SCML; running their configuration apps cured it (SSM 54226). So a switch fault may really be a seat module setup issue. U0562 means module B frames reach the bus but fail checks; U0261 means they stop, U0561 concerns switch A. No bulletin names U0562. The affected seat may not respond to its switch.

Likely causes

Receiving seat module not configured for the installed switch and seat equipment
Software fault in the second seat switch module
Connector or harness under a movable seat damaged by seat travel or objects

Symptoms

  • Passenger or rear seat does not move when its switch is pressed
  • Seat moves only in some directions
