Answer
Joseph, You need to read the codes.  If this is an early 940, the port is in the engine bay.  Read both #2 and # 6.  Ill give you an example with #2. Turn key on to first pos.  Put connector in port 2, hold button for 5 seconds.  Count the flashes, Example, 2-3-2.  After that flashes, then hit button again.  If its a different code, hold another 5 seconds.  Keep doing this until the first code read comes back up.  NOW hold button for 10 seconds.  Light will be steady. Hold another 10 seconds and light will go out.  Memory is real easy.  Set the seat where you want it and hold one of the buttons for 5-10 seconds.  Now its in memory.  Roger
