Good morning all, I have a 2012 Mercedes Benz GL350 Bluetec in the front fuse box in the engine bay. I had the 40A compressor fuse keep blowing. The compressor was working but very loud. I made a mistake and pulled the compressor relay the third one from the left side the green one and tried another relay and got some sparks and more error codes. Lesson learned to use all original relays from dealer only. I ordered a new compressor as well.

Now i am getting the following error message that will not clear outlined below:


System: ISM-Shift Module
Code:U010087
Description: Communication with the combustion engine control module is faulty. The message is missing
Status: Stored and current
.

System:: SAM-F-Signal acquistion and actuation module front

Description: Component "F58KH (Terminal 15 relay) is faulty or missing, or the feed wire has open circuit.

Any help on locations of these items so i can check them would help.
Thank in advance

 

what was the solution? I made the same mistake and pulled the compressorrelay and tried another relayand got some sparks. the car doesn't start anymore.

 

Yeah hey
I did the same thing, had to replace the entire front fuse box in the engine bay. You will have cooked one of the circuits on the internal circuit board, if you cant wait to buy another fuse box, you could try pulling it apart and re soldering the busted circuit lines, and then replace improper relay with proper relay of course, but your chances of success with this method are probably low. Better off replacing the whole box.

Cheers

 

Be careful, I also had to replace the ISM after a situation like yours, and as @General Disturb has written, I have soldered the busted circuit box, but as this wasn't the best solution, as sometimes I got different errors, I just replaced the fuse box.
I wish you luck.
