B0533 is absent from the J2012 lists that can be consulted publicly; GM's PIP5094 merely names it as a circuit keyword for 2014-and-earlier models without saying what it covers. The title assigns it to the lock motor of the right rear door. In the Saab 9-3 the right rear door module watches this motor and reports B3135 02 if its line is shorted to ground while the car is being locked or unlocked. Rear doors often add a second actuator: the 2011 Saab 9-5 drives a child security relay feeding both rear latches and stores B3930 02 when that circuit is grounded, which also takes the power locks out of service. Separating such a child-lock fault from the main lock motor is the first diagnostic step. Left rear: B0532.
