Storing memory positions, function

 In this document the door control module is designated as follows on the models
215 - Left/right door control module
220 - Left/right front door control module
as left front door control module (N69/1), right front (N69/2).

Function prerequisites:

 Circuit 15R or 15 ON

Together with the storage of the driver's seat position in addition the inside rearview mirror, the outside mirror as well as the steering column position are stored in the relevant control module key-related.

Memory locations up to 31.5.01

The positions of the driver's seat and front passenger's seat including the adjustments of the multicontour backrest (special equipment) can be stored on two memory locations.

-----------------------------------------------------------------------------------------

Memory locations as of 1.6.01

The positions of the driver's seat and front passenger's seat including the adjustments of the multicontour backrest (SA) can be stored on three memory locations.

The positions are stored in the following control modules:

Driver side

 Seat position: Left front seat adjustment control module with memory (N32/1)

 Inside rearview mirror position: Overhead control panel control module (N70)

 Left outside mirror: Left front door control module (N69/1)

 Right outside mirror: Right front door control module (N69/2)

 Steering column position: Left front SAM control module (N10/6)

Passenger side

 Seat position: Right front seat adjustment control module with memory (N32/2)

-----------------------------------------------------------------------------------------

Rear seats

(model 220 with electrically adjustable individual rear seats only)

 Seat position: Rear seats control module (N25/6)

Up to 31.5.01 store driver's seat position with associated mirror and steering column positions

The currently adjusted positions are stored by pressing the memory switch (N69/1s9) in the left front door control module (N69/1) and then within 3 seconds, the memory 1 switch (N69/1s6) or memory 2 switch (N69/1s7).

If at the same time no other switch in this switch group is pressed, the left front door control module (N69/1) sends a message to the CAN. The respective control modules receive this request for position storage and check whether valid values are supplied via local position measurements.

----------------------------------------------------------------------------------------

If this is the case, the current positions are stored in the non-volatile memory.

Up to 31.5.01 storing front passenger's seat position

The currently adjusted front passenger's seat position is stored in the same way as the driver's seat position.

It is triggered by pressing the memory switch (N69/2s9) in the right front door control module (N69/2) and then, within 3 seconds, memory 1 switch (N69/2s6) or memory 2 switch (N69/2s7)

Storing left rear seat position

(model 220 with electrically adjustable individual rear seats only)

The currently adjusted rear seat position is stored by pressing the memory switch (N69/3s10) in the left rear door control module (N69/3) and then memory switch 1 within 3 seconds (N69/3s3) or memory 2 switch (N69/3s4) or memory 3 switch (N69/3s5).

----------------------------------------------------------------------------------------

The storage process for the right rear side is analog to the left rear side. In the process the memory switch (N69/4s10) in the right rear door control module (N69/4) and memory 1 switch (N69/4s3) or memory 2 switch (N69/4s4) or memory 3 switch (N69/4s5) are used.

 In order to avoid faults during storage it is necessary that the voltage supply is applied to the control module for a further five seconds at least.

As of 1.6.01 also a revised storage process

There are two ways of storing the respective positions:

For the driver's side

a) If the memory switch (N69/1s9) is kept pressed and additionally one of the memory 1 switches (N69/1s6), memory 2 switches (N69/1s7); memory 3 switches (N69/1s15) is pressed for t  40 ms, the storage process is thereby concluded.

b) Press the memory switch (N69/1s9) for t  40 ms and then release again, then within t  3 seconds, press the desired memory location via memory 1 switch (N69/1s6); memory 2 switch (N69/1s7), memory 3 switch (N69/1s15) for t 40 ms so that the storage process is concluded.

If during the storage process no other switch from the switch group is pressed, the values are sent from the respective door control module to the relevant control modules via the CAN.

These control modules check whether the local position measurement supplies valid values. If this is the case the current positions are stored in the non-volatile memory.

The storage process for the front passenger's side is analog to the driver's side. In the process the memory 1 switch (N69/2s6), memory 2 switch (N69/2s7), memory 3 switch (N69/2s15) and memory switch (N69/2s9) are used.
