B0601Mirror Adjustment Passenger Side Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0601 is not covered by the public J2012 lists or by any accessible manufacturer documentation. By title it concerns the adjustment circuit of the passenger exterior mirror; FMVSS 111 only demands that it can be tilted, not remote control from the driving position, yet most are motorised. TI's application brief describes the usual layout: two small brushed motors below 1 A, driven by three half-bridges sharing one common leg. Saab's 9-3 passenger door module logs B1723 02 or B1724 01 for a shorted motor output. GM's 2011 Saab 9-5 drives this mirror from the passenger window switch; an internal fault there sets B154B 39 and suspends mirror movement while it persists, and the stored code clears after 40 cycles.
