Customer reply replied 2 years ago
Relay to starter is good , power is getting to the relay , fuses are all good . Grounds have been checked and good
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok so you replaced the ignition switch or the steering lock on the column ? Just to be on the same page

Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok can you turn the key on and test all the fuses in the drivers Sam fuse box and make sure they all have power ? Tell me which ones do not have power of any. We are not testing for blown fuses I'm looking to make sure all the circuits are alive like they should be.

I also get a loud relay click coming from the prefuse junction box by the battery when the door is opened ofter the car has been sitting for a while "10-15 mins" with no activity
Customer reply replied 2 years ago
Well the esl went I had got a new one programmed and I also got an emulator in case one or the other didn't work . But esl seems to be working correctly . Once back together I got a no crank
Customer reply replied 2 years ago
Sent out esl / eis systems to a reputable mercedes programmer as the dealership would say it's impossible but I've done business with the guy for years have never had an issue .

Sorry my kid bumped my mouse and opted me out. I am still here !! Reading your recent texts

Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok. I have been a dealer tech for 16 years and I have seen and heard of people getting that done but it's beyond my smarts lol. So in my mind if all was fine until the ESL then there's a authorization issue but that would not let it shift out of gear so it's conflicting. Ok so let's start by making sure all the fuses have power. We won't assume the issue we will prove it. So as of now I think the issue is with the eis/ESL pairing. But we'll come back to that. So let me know about the fuses. Lou

Customer reply replied 2 years ago
Ok when I get home I will let you know about the fuses , and I was thinking some sort of drive authorization beig the culprit as well , or that prefuse box but it has power so I'm not sure . I'll start with the fuses for you in a bit
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok. I'll be up for a little more tonight but I will definitely see your messages in the morning. I'll do what I can to assist.

Customer reply replied 2 years ago
Sounds good if I don't get to it tonight I will right after work , trying to ween out everything I can before I take it to my mercedes dealership. It's 150 just to hook it up to star and pray that even tells me anything .
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Well I can tell you the diagnostic machine is only as good as who can read it :) if you don't know what your looking for you won't find the issue. Not against you it's some new dealer techs that don't have the experience.

Customer reply replied 2 years ago
Going out there right now I'll let you know what I find
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

OK , assuming you are heading out to test the fuses.

Customer reply replied 2 years ago
With key on every fuse has power except 22,23,24,25 they just have continuity
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok this is common it should be the circuit relay 15 that powers these. I'll check and be back. Nice job
