Seat adjustment, functional
description

The 8-way seat is equipped with a
seat and mirror memory function.

With this system individual seat and

mirror adjustments can be stored in
the memory. Each of the memory

store the individual settings for one
person.

The seat and mirrors will move
automatically into the required
position by pressing the appropriate
button when there is a change of
driver.

In the driver's seat adjustment, the
position of the exterior mirrors (left

the position of the right exterior
mirror for reversing can be stored
and recalled for each memory button
-1-, -2-, -3-.

The adjustments stored on a
memory button can also be called up
using the key for the radio wave
remote control.

The memory system can be turned
off at any time using the red switch -

On Board Diagnostic (OBD),
functional description

It is an independent system and has the On

Board Diagnostic (OBD) address word 36
"Seat adjustment driver's side".

The seat adjustment control module -J136-

is located under the driver's seat and is
connected to the convenience system via
the CAN data bus.

It is equipped with a DTC memory. The On

Board Diagnostic (OBD) connection is
located under the driver's knee bar to left of
the steering wheel.

The control module detects malfunctions in

the system and stores them in a permanent
memory.

To commence troubleshooting, initiate self-

diagnosis and retrieve the stored information
with the V.A.G 1551 scan tool.

V.A.G 1552 System tester may also be

used.

The malfunction information displayed is

used to refer to a DTC table with notes on
the possible causes for directed repair
measures.

Malfunctions which can be attributed to a

temporary open circuit in the wiring or a
loose contact, will also be stored. These
malfunctions will be displayed as sporadic
DTCs "SP".

The individual operating functions are

described in the following description.

Memory system, initializing

Note:

All data stored for the seat and mirror settings

will be lost when the vehicle battery is
disconnected.

This data will be retained in future control

modules even after the battery has been
disconnected.

Each new setting stored on the same button will

erase the previous data.

It is not possible to store settings on the

memory buttons if the red switch is switched-off
(switch protrudes).

The battery voltage must not be below 10.5 V.

Otherwise the system detects low voltage and
will store a malfunction in the DTC memory.

The following test steps must be performed for

the initialization:

- Open driver's door.

- Switch on ignition.

- Then move the seat backrest forwards as far as

stop.

This position will be recorded for reference when

the stop limit switch-off occurs.
