B0562 is missing from public J2012 lists, and no manufacturer documents it. The title names the circuit of the backrest recline motor in the driver seat, which in Chrysler's US4682088A tilts the seatback through roughly 38 degrees. Saab's 9-3 reports this motor as B1785 in the driver seat module: 04 when an output voltage stays too low (open circuit), 0B when draw exceeds 40 A, for example with a jammed recliner gear; memory positions are then unavailable. GM's 2011 Saab 9-5 adds a Hall sensor inside the recline motor, fed with 12 V; its signal faults are logged separately as B1825 01/06. For the driver this usually means the backrest stays at its last angle.

Likely causes

Recliner gear jammed or worn, motor draws excess current
Recline motor open winding or brushes worn
Wiring between seat base and backrest broken
Seat module output faulty

Symptoms

  • Driver backrest angle cannot be changed
  • Memory positions are not reached
  • Motor hums or clicks without backrest movement
