Function of preliminary block switch-off - GF91.29-P-4003A
MODEL 210.081 /281, 210 (except 210.081 /281) as of 1.3.97 with CODE (275a) Memory package (driver's seat, steering column, rearview mirrors)
MODEL 208 with CODE (275b) Memory package (driver's seat, rearview mirrors)
Function
If the motor moves against the mechanical end stop, motor lock-up is recognized by the position measurement feature. The driver-side ESA control module (N32/1) or passenger-side ESA control module (N32/2) stores the position measurement counter position. The next time the seat is moved in the direction of this end stop, the motor is slowed down just before reaching the stored position. This prevents the seat from hitting hard against the end stop.
The stored position is erased when
- the adjustment mechanism in question has been actuated 250 times or
- the control module was disconnected from the power supply or
- the remaining travel between the stored positions for an adjustment direction is less than 90 % of the total possible adjustment travel in that direction.
