B0223Recirculate Position Command 1 Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0223 does not appear in the publicly available J2012 lists, but General Motors uses it for the recirculation door actuator. On GM Global A cars such as the Saab 9-5 and 9-4X of model year 2011 that actuator is a stepper motor with four control lines; B0223 01 means command circuit 1 is shorted to battery, B0223 06 that it is open or low. The module only checks the outputs when the motor starts to move, not while it runs or once the target is reached; it then switches the output off and deactivates that motor. B022A is the second recirculation command circuit. GM bulletin PIT5383A for 2015 Buick, Cadillac, Chevrolet and GMC models lists B0223 among HVAC codes and inoperative recirculation, fixed by reprogramming the HVAC module. The airbag lamp meaning once given here belongs to B00D2 in J2012.
