In emergencies, such as low voltage of on-board electrical system or failure of communication with intelligent servo module (A80), the key-P function can still be implemented. In these cases, the emergency motor in the intelligent servo module is powered by N73 and triggers the emergency.
Parking function. If the low voltage of the on-board electrical system is eliminated, the emergency parking function will be disabled and the intelligent servo module will return to normal working condition. The sequence of emergency parking functions can be divided into the following steps: the sequence of starting position functions, the sequence of working in the middle position, and the sequence of ending position functions.
Cancellation of stop position function order and function order.
In emergencies, such as when there is insufficient power in the on-board electrical system, the emergency motor is powered by the on-board electrical system battery (G1/4 of the starting battery before the 2008 conversion) through the control module N73, and the eccentric shaft is rotated.
The rotating eccentric axially depresses the separating screw of the left half slide seat. This causes the mechanical connection of the left and right half sliding seat to be cut off in turn.
The pre-compressed coil spring pushes the two semi-sliding pedestals apart, and the right semi-sliding pedestal slides to the right side along the screw, and obtains the range of gear selection rod pushing position P. The eccentric axis continues to rotate until the emergency motor is no longer driven. The eccentric axis position sensor records the actual position of the eccentric axis.
If emergency signals are no longer sent (e.g. caused by low voltage of on-board electrical system), the emergency function of P-gear will be disabled. The above motors are suitable for Mercedes-Benz emergency motor through the control module N73 Emergency-P.
