Easy entry, driver seat, function - GF91.29-P-2014PP

MODELS 203.0 /2 /7 with CODE (275c) Electrically adjustable driver seat, steering column and exterior mirrors with memory with CODE (242b) Electrically adjustable front passenger seat with memory

Fig 1: Identifying Easy Entry, Driver Seat, Function

General information

In order to make it easier to enter and leave the vehicle, the steering column is moved upward and the driver seat backwards.

After getting in, the steering column, driver seat and outside mirror are moved to the driving positions last assigned with the transmitter key.

Adjustment of the driver seat is described below.

Function requirements

Function in instrument cluster activated
Driver seat normalized

Move to entry/exit position

Function

In the event of the following changes in status:

transmitter key withdrawn or
opening of driver door with circuit 15R ON or
open driver door with circuit 15C or
opening of driver door when transmitter key not inserted, the fore/aft motor (M27m1) is actuated by the driver-side front seat adjustment control unit with memory (N32/1) (driver seat in rear end position).

For this, the following information is scanned over CAN-B (CAN-B) and processed by the driver-side front seat adjustment control unit with memory (N32/1):

The EIS control unit (N73) sends the circuit status,
The rear SAM control unit with fuse and relay module (N10/2) sends the status of the left front door contact switch(S17/3),
Instrument cluster sends "easy entry/exit activated".

During the "easy entry/exit" function the "head restraint presetting" function (only and ) is not performed.

Function abort

Adjust request for seat or steering column
Change of circuit 15 OFF in circuit 15C, circuit 15R or circuit 15
Close driver door at circuit 15

Move to drive position

Function

In the event of the following changes in status:

No circuit → circuit 15C (with driver door closed),
Circuit 15C → circuit 15R (with closed driver door),
Circuit 15R → circuit 15 (with closed driver door),
Closing of driver door with circuit 15 ON.

the fore/aft motor (M27m1) is actuated by the driver-side front seat adjustment control unit with memory (N32/1).

The driving position is stored in the driver-side front seat adjustment control unit with memory (N32/1) for each key.

The transmitter keys are managed with the aid of the memory block number. The memory block number is issued by the EIS control unit (N73).

Abort conditions

Missing function requirements
under- or overvoltage
Adjust request (memory or manual)
Circuit change
Driver door opened with circuit 15C with circuit 15R

Repeat limiter for easy entry/exit function

Repeatedly inserting and removing the transmitter key causes the equipment to move between the easy entry/exit positions and the driving positions every time.

To prevent this, the number of cycles is limited to 5. The counter is reset, when the following prerequisites are fulfilled:

C. 15R ON and
The status of the driver door is changed
