NECK-PRO Fuse Keeps Blowing

Hey Guys, I'm new to the forum, but definitely not to Mercedes! Anyway, it's not very often that I can't figure out a problem but this one has me a little stumped and I can't seem to find anything on it anywhere.

I had my SRS light come on a couple days ago so I ran the diagnostics on it and was getting code B1C1113 and B1C1713 - NECK_PRO head restraint (both in this case) has a malfunction - There is an open circuit.

Started at the most logical place for an open circuit- the fuse box. Pull fuse 37 and sure enough it's blown. I replace the fuse and think I'm good....take it out for a ride drive a couple miles and sure enough it blows again. I try one more time - take for a drive. This time I go 20 miles and park. All is ok so I thought maybe the replacement fuse was bad. I get back in the car later in the day and before I get out of the parking lot to head home it blows again.

It seems to be happening upon acceleration if i go a little heavier on the throttle or when I get on it merging on the highway.

Any idea as to where to start diagnosing whats going on in the circuit?

Thanks!

I just wanted to give an update as I was able to repair the issue. I identified the circuit and started to trouble shoot the issue. Since it was happening while accelerating or going over bumps, I had a hunch that it might have something to do with the wiring in the seat.

I replaced the fuse started the car and sat in the passenger seat, moved around vigorously and nothing would happen. I moved over the the driver seat and did the same thing and sure enough the fuse would blow so I pulled the drivers seat to check the harness.

As I got to the hinge in the seat I pulled the harness out as best I could and sure enough I found a small hole worn through the sleeve of the harness and just enough insulation worn off one of the neck-pro wires to expose copper. The wire was grounding out to the metal of the seat. I wrapped the harness in self adhering rubber electrical tape then another layer of traditional vinyl electrical tape. Put it all back together and we are good to go!

Hope this may help someone out in the future.
