Hello, I have the following problems. My buddy bought an ATEGO 815. Unfortunately, the seat (ISRI) is somehow defective. It is in the lower position without the air bellows. He does not react to the keystrokes (on / off etc..). At the Stg. the green LED lights up After the plugging of the red ECU sounds the summer and in the display I think SIL or something.. Who can help me with the troubleshooting or. how do I go on? Unfortunately I also have a schematic icht to measure anything. Poti from the seat etc.. Add a few photos including the vehicle registration with the type of truck If more photos are needed and / or descriptions I like to create them.
