Function description, pin coding of memory control units

 

The memory control units in the front seats are the same for the left and right.

Address words 36 (driver's seat memory) and 06 (front passenger seat memory) are assigned by default at the factory by the wiring in the vehicle electrical system (pin coding, current application to different pins).

• The address words are also retained when the control unit or battery is disconnected.
• After replacing one control unit the new control unit (after ignition on) is automatically assigned the missing address word.
• If both control units happen to have the same address word despite this (e.g. due to swapping over), the control units cannot be addressed by self-diagnosis.
• The control units can then only be accessed when one of them is disconnected.
• By opening one door and operating the memory function you can identify which address word is in both control units. Ignition on and ignition off then driver's door open and both seats with memory function = address word 36. Front passenger door open and both seats with memory function = address word 06.

 

Procedure if address word 36  in both control units.

•             Ignition off
•             Unplug all connectors between seat and vehicle body from both seats, except             airbag.
•             Ignition on, ignition off
•             Connect only front passenger seat
•             Ignition on
•             Run program J136 - Seat memory control unit, adaption to DS/PS         
•             Connect driver seat
•             Interrogate and if necessary erase both fault memories
•             Check functioning of seats

 

Procedure if address word 06  in both control units.

•             Ignition off
•             Unplug all connectors between seat and vehicle body from both seats, except             airbag.
•             Ignition on, ignition off
•             Connect only driver seat
•             Ignition on
•             Run program J521 - Seat memory control unit, adaption to DS/PS                     
•             Connect front passenger seat
•             Interrogate and if necessary erase both fault memories
•             Check functioning of seats
