MTLEADER Posted December 31, 2021 Share Posted December 31, 2021 I am a member of a couple ford fusion forums and I have a post here also but my car is doing so strange stuff and it doesn't seem to make a lot of scene to me. I thought I had fixed it but it happened again the other day, I know I'll be told to go to a dealership but no money to do so right now. It is 165$ here just for a diagnostic witch is nuts. This is the link to the posting in the other forum, but I do need a tech guys help here if one could help I would be very grateful. Thanks. I have physically traced every inch of wire I could see and removed covers to do so and cannot find a short, burnt or exposed wire anyplace. Only thing I can figure is the aftermarket amp and sub is somehow doing this so I am going to disconnect it and try to reset the codes and wait to see if it happens again. I also have a CV axel that is bad to change out, but see no fluid leak from it but also wonder if this could be the reason for the car going to limp mode and the warning lights. https://www.fordfusionclub.com/threads/2019-fusion-s-limp-mode-or-something-else.767703/#post-10159270 0 Quote Link to comment Share on other sites More sharing options...
MTLEADER Posted January 2, 2022 Author Share Posted January 2, 2022 An update, went and got car battery tested and had one bad cell in it so got a new one for car. Placed it in car and bam no change. Pressed in brake pushed start and short crank and stops wont do anything cept show cluster lights of all the system falters and wont let me reset battery or erase DTC's. So I put battery on my charger and will try again on the marrow. If nothing might take alternator in to get checked next and go head butt the used car guy I bought this from. Nothing but issue after issue with this Gem of a car. I liked driving the rental one me and wife got should have bought that car lol. 0 Quote Link to comment Share on other sites More sharing options...
MTLEADER Posted January 27, 2022 Author Share Posted January 27, 2022 Still no one to help? Good thing I don't wait for help. So I have found that my DLC has a resistance of 120 Ohms on pins 6 and 14 that is bad. So my network isn't working so the cars computers wont read each other. Anyone have a wire diagram for this? I cannot find one with online search been trying for 3 days now. Even if only a link please really need it thanks 0 Quote Link to comment Share on other sites More sharing options...

Did not want you to think your posts were being ignored..But unfortunately, the members who I know to be techs or have tech like knowledge have not been active lately. And the information you are looking for is beyond my skills to give much assistance. Hopefully someone else will be able to jump in to help. Good luck. 0 Quote Link to comment Share on other sites More sharing options...
MTLEADER Posted January 27, 2022 Author Share Posted January 27, 2022 (edited) I'm frustrated is all car is only 3 years old and have had nothing buy problems from the day me and my wife bought it.(we got it used for 12k with 32k miles on it) It's over warranty and the cost for Ford to work on it is really sick 165$ an hour in California. Ford used to be a good family oriented and run company what has happened to it? They have one of the worst warranty's of any car maker. If it was up to just me we would have never bought this car but happy wife happy life right. The OBD read outs might as well be Sanskrit to me. I did understand that there had to be an issue with the cars pc's talking to one other though so I got to this point. I'll figure it out just taking a long ass time. Wish I could just rip all that tech crap out of the car get back to how cars were before I was born lol but I can work on them good old American cars this might as well say Windows PC on the side of it LOL. OH and BTW I see you have an MKZ 2018 how is that car the color mix sounds really nice. Edited January 27, 2022 by MTLEADER 1 Quote Link to comment Share on other sites More sharing options...

Is it also outside the 5 year/60,000 mile Powertrain Warranty, in case it is a Powertrain related issue? The aftermarket components also throw a curve ball into the entire situation.

MTLEADER Posted January 28, 2022 Author Share Posted January 28, 2022 Yes it is but I think it is the main computer in the car if it is it is covered by 8 year / 80k mile federal emissions warranty I believe. I cannot figure out what is making the car not "talk" on the network. So before I make a mistake and mess it up more or worse I'm going to have it taken to Ford. Still need to learn the CANBUS network stuff cause it is really expensive to have the dealership fix anything if I cannot myself. 0 Quote Link to comment Share on other sites More sharing options...

MGMMobile Posted December 6, 2022 Share Posted December 6, 2022 Do you still need diagrams? If anyone needs a diagram for the 2019 ford fusion/MKZ, I have a book ? 0 Quote Link to comment Share on other sites More sharing options...
