Claim 9:
10. A method for operating a parking lock device (10) as claimed in claim 1, comprising the steps of:
triggering (51) of the latching mechanism by the second actuator (F2) or by the first actuator (F1) in the event of a malfunction of the second actuator (F2) and thereby engagement of the locking position (P) by a force effect of the engagement spring (16) or rotation of the drive shaft (AW) by the first actuator and thereby engagement of the locking position (P) by the first actuator (F1) in the event of the malfunction of the second actuator (F2);
renewed loading (S2) of the engagement spring (16) by rotation of the rotary mechanism (1) by the first actuator (F1) during the locking position (P) and engagement of the latching mechanism;
movement (S3) of the rotary mechanism (1) back into the neutral position (nP) by the first actuator (F1), wherein the position sensor (PS) detects a movement of the permanent magnet (PM) relative to the position sensor (PS) and ascertains whether the locking pawl (2) is in the locking position (P) or in the neutral position (nP) on account of the rotary mechanism (1).
