County government fleet tech of 30 years here. I had this happen to us one time, same exact thing. Found that connector unplugged. I happened to look down at the floorboard over there and there were mud marks on the kick panel where it looked like they drug the side of their boots across the kick panel cover. The cover was slightly dislodged and out of place. I took off both covers and found that connector unplugged just like you did. Just absolute sheer luck i found this!
I bet the kick panel had been removed at some point and the connection became loose enough over time by someone originally kicking that connector loose.
Same here. I work at an independent repair shop in Louisiana. Had this on an oilfield service truck that came in for an intermittent no crank with no radio and A/C. Was starting to check fuses in the BCM and noticed the connector was not fully latched.
I used to disconnect the crash sensor on my business van whenever we went on vacation as a theft deterrent. It was an E350 and I thought IF someone loaded that up with tools from my shop they could get away with a lot.
The flap on these connectors often have tension against the lock tab you press down, you've seen how you sometimes press it and it begins unlatching itself slightly. I could very well see the panel flexing against the pin with somebody's foot and 1, 100, 2000 miles later fully unlatching itself. Awesome find.
I felt for you while watching the video. I was a weapons troop in the AF on fighter aircraft and I remember a malfunction on the weapons system in a F-100. Everything for our systems was buried down under the rudder pedals so me being small I had to get on my back with a flash light and slide down in our area and with a volt meter made checks. Couldn't find problem on first go so the heat was on as million dollar aircraft was grounded until problem was corrected. Went over the wiring sch. again and found a relay I hadn't checked the first time. On my back again with my trusty flash light and was handed a volt meter once I was in the hole. That relay had failed and so glad I found it as the heat was really on to get this aircraft back active. I changed out the relay. This was in the mid 1960's so no computer things thank goodness.
Went down a rabbit hole because the customer didn’t tell the real story the first time,not your fault you were going off misinformation,great video and fix 👍
That’s a common Issue with the 2011-2014 F150 - it’s the first thing you should check with a no start situation. It’s usually caused by the passenger kicking that plastic cover. I’ve seen it many many times with this particular model.
Ive had 2 vehicles thru my shop with same problem luckily i knew where to look as it had happened to me personally on a 2013 F150 twice! Tow truck driver told me it happened to him! And he checked same spot and voila my truck turned on! Each time it was after i had turned off my truck after a random electrical error on my dash! We now check these on nearly all 09-14 f150 trucks to avoid customer future headaches!
I think the radio teck was working on it and turned the power off to it ,and not disconnecting the battery.He probably thought he forced it back on ?but didnt. The owner is extremely lucky it wasnt in the winter or long road trip and that he has you as a mechanic .Great Video .Thanks.
Good diagnostic video! Sometimes it's good to go down the rabbit hole and learn from your mistakes. No auto technician is perfect, I'm glad you showed the bad part of the diagnosis!
This is why it is imperative to have a clear understanding of the clients concerns and as detailed as possible. Technicians should assist the service writers and help train them to ask the right questions . Communication is an EXCHANGE of ideas and information . You have to remember the client knows something is wrong but generally doesn't know how to express it in terms that technicians understand .
2013 ram 1500 had one that had no power on half the fuses under the hood. Looked under the dash visual checking and just looking at connections and doing a little wiggle testing, and my elbow happened to hit a connector near the firewall and it lit up the cluster. It was half disconnected. Happened to be the customer would tap his boot under the dash and must have dislodged the connector. Great videos, enjoy them.
Before I retired, I had my own company installing and servicing heavy duty HVAC and boiler systems in the goldfields of Western Australia. I always told my guys to always question and listen to the plant operator because his knowledge of his plant would often lead them to the fault or problem.
Thanks for all you do! I save these videos for my class to show when I am teaching proper diagnoses and how something so simple can cause you to go in so many directions!
First step in any and all troubleshooting is a thorough visual inspection. Military taught me that and you'd be surprised how often that comes into play. Great job in your troubleshooting path though.
I think it’s most likely that someone was in there earlier (perhaps even years earlier) and just didn’t make sure the connector was completely locked. With the cam mechanism on those connectors that mechanically (disconnects) pushes the connectors apart as it’s flipped open the vibrations can work them open when not locked. I can’t know this for sure but I’ve never seen a perfectly good functioning and well protected connector just overcome the locking tabs that keep them 100% connected. Happy Thanksgiving and thanks for the video!
That was an education all around. 😂 glad you got it fixed and im sure the customer was glad it wasnt some crazy expensive part that went bad. Great job!
When I was a service writer, I did my best to get as much information from the owner as possible. The owner of the dealership didn't like me doing that, but the techs loved it. When I went back to working on cars. I never had a service writer that wanted to ask the customer questions. And boy did that piss me off. I was always telling them to call the customer and get more information.
I feel ya I do alignments. And when they won’t tell me WHY the customer wants alignment. I remind them it’s like going to the doctor and refusing to communicate and making him guess.
Had a simular situation and it ended up being water intrustion in the tail lights. $2800 later for tail lights and harness. This one had the radar sensors in them. These new cars with all these unessary options is ridiculous. Thanks for sharing!
Had the same issue on a 2018 f-150. Taillight had a slight crack. Water intrusion in the lane assist module. Replace the taillight and module. Had to program that module with Jbox. All issues gone.
Had the same issue on a newer Ram pickup. The blind spot radar in the tail light is on the network and the water in the tail light was shorting the network and pulling it down. Dealership anted to replace the $2000 radio and they wanted a second opinion. They didn’t want to believe me that the tail light was the issue until I proved it to them. 😂
Most of my Diagnostic jobs are chasing faults that are caused by previous work done on cars by other mechanics, it unfortunate that mechanics accidentally end up making more work for ourselves in future
First thing that went through my head was a possible bcm. Perform a full scan. See what modules are talking. Check all powers and grounds. Verify any possible network issues. Start narrowing down.
I believe there is a bulletin on that connector for a no start something about coming disconnected when passengers get in there and start kicking around
That was awesome! Watching you troubleshoot something is great since we all have to do it at one point--and we all screw up and waste so much time. Seeing the professionals doing it to is very instructiional. Thanks for making this available to us.
It is critical to get the correct description of the failure mode from the customer!! I have found that it is often required that the question from a service advisor or the tech be repeated to see if the story matches from both inquiries to that customer! This gets more challenging to determine the correct description of the failure event when there is a language barrier with the customer.
Great video. In all fairness customer led you to believe it shut off while driving. I haven't had same issue but have been misled information from customers before. Been doing this for over 36 years now..chased my tail a few too many times .. The information I've learned from you have helped me out many times already .. thanks
36:50 I think I can see holes that line up between the latch and the connector, possibly where a sort of tie/ziptie can be put in to hold the connector down?
I was wondering if it was the same as a vehicle worked on a couple years ago. 23 minutes in, I saw the connector. As soon as I saw all of the communication codes. I started checking the networks at the DLC. I found it a little sooner than you did. But I have been a Ford tech for years. Great video!
I would suspect a previous service guy probed that connector and used a probe too large for the socket. Likey more than one contact is sprung. Then, they didn't completely latch the connector. Talk to customer regarding recent electrical issues. I'd suggest a pin drag test on all the socket contacts to avoid a comeback a few weeks later with some other obscure comm issue. Contact springs can be retensioned by extracting the socket and using a fine pick (needle) to bend the spring back into shape.
Good one Sherwood! Most of the time it's lack of information and transparency. I don't know why, but customers always hold back valuable information. I guess they believe it will cost them less. Mysterious missing fuses, disconnected connectors, etc. In the end, it cost them more since it sends techs down time wasting rabbit holes. Nice diag. Your thought process was there. The order of symptom information wasn't. Great job again! Thanks, keep 'em comin!
I will from here forward ask customers if they had their vehicle in another shop for some other issue in the past 6-12 months. Reason being it is possible someone else checked it over for something else and touched that connector and after reconnecting it never locked it back in and after a period of time the vibrations of operation slowly worked the plug loose and caused this new problem. I work at a commercial truck leasing shop and hate working on new customers own vehicles that have had too many hands on them and never know what is what because not all shops are professional and a lot of shady crap can go on leaving you with a bees nest of issues you have to pick at one by one that eats up time.
That was great thanks for sharing the whole thing, nice to know I’ve got a lot more rabbit holes to go 😂. Liked how the customer second interview helped and the visual find
If the rear doors are closed but it says it's open, check the wiring harness for the door. They are prone to break a wire or two. I went ahead and replaced my old harness with a new one.
I’ve got a 2011 3.7 L and this falls underneath the category of the same diagrams and specific routing of each component electrically. I appreciate I’ve learned a lot too….. thank you very much
Hey fellow technician someone has previously been in that area for some reason and did not secure all the connectors. Then time and vibration cause a no start condition .A open circuit issue exists because of this and have seen this issue a few times with this model style fuse box. P S we all have seen the inside of a rabbit hole and the next time you are there have some carrot juice and while you are looking at pictures of previous visitors ask yourself what should I have check/tested before I came here? (Iam a 40 yr tech in this field and have been in that hole many times.brush the dirt off and store this in your memory and this will make your diagnosis flow routine much better/ quicker)
Locksmith in WPB FL 20 years Seen it a crap ton. LARGE FOLKS have always been sitting on that side when I’ve found it. As soon as the Pats code show up all the shops call us for this problem. On the 11 to 14 F150.
I watch your videos because you're always so transparent. We've all been there-sometimes the more we learn, the easier it is to forget the basics. Pin retention on the BCM?
Guessing they had something down in the floorboard, like a bag or something, that found its way in there via wind or a foot and when it was removed it pulled on the latch.
I had one in the shop about 2 months ago with the same problem. I was going the same direction as you but accidentally bumped the connector checking fuses and got lucky
Apparently pulling off the road jarred the partially latched connector loose, perhaps hitting a pothole or the rough transition of the road and emergency lane. Good find!
I feel like I’m not a dumb ol bodyman. I was watching the video and when you had all of those faults for lost communication, in my head my first thought was something is unplugged. And holy shit when you found it I jumped up and said I KNEW IT! 😂. I take interior out all the time and when post scanning the vehicle it will be slap full of lost communication faults from unplugging a lot of connections. Well I’ll be damned I felt smart for second when it ended up being a plug.
I, for one, feel that it's great for him to go down the rabbit hole. I would have started someplace else. Another commenter stated that he would have started differently than I would have. We see Royalty went through different items and found an unhooked plug, whereas, Bisenbart found the same item, on another truck at another time!, if I understand. Now I know some of the easy things and places to check for, BEFORE I start down that rabbit hole!!
I have seen that same type of lever connector on Fords rattle loose and dissconnect, but never in that particular location, it's usually where a harness locator has come loose or broken and allowed the weight of the harness to bounce and work that lever loose. And it's generally on lifted trucks or slammed focus st.
Usually when the bureau gets a string of complaints about a shop or regional shops they might do a "sting" op. The best way to rule that out is if the problem is intermittent. They lose teeth in court if they hit you with an intermittent problem. This could have been a plant. It doesn't matter how the customer presents the problem. What you see is what you go on. This from a convo I had with an inspector in California some years ago but I think the logic still stands. Open for updates on this.
Had a guy at work have a very similar thing happen with his F-150. He went to the dealer which was where he found out this is a common problem on those years. At first I wasn’t sure based on the “it shut off while driving”, but after 10-20 minutes into the video, I started wondering if they gave you bad information. Then I also remembered the guy at work. I started saying look in the kick panel. Like you could hear me 😂 Low and behold you reset, get the correct info from the owner, and viola. Ended up at the right spot. I wonder if this issue is on identifix? Either way you got it, which is the end goal. Well done!
I had the exact same thing happen, though, i caused it myself when I removed the blower motor. Put it all back together, and it wouldn't start. After an hour or so, I found the same connector loose just like that one.
someone has been in there, they just don't come undone. i work on a lot of the F150s, and Super Duty's, and mostly find OE splice and ground issue. we have the ones where the end user kicks the lower panel off and or is missing. not too many modules bad though, usually their feet cause the issue with connectors or wiring.
I've gone the wrong direction, from listen to the client. You listened to the client also. I don't think my clients (my kids) do it intentionally but they real know nothing about cars. One time my daughter told me she lost power steering at stop signs. She never told me, that the cars engine stopped too.
I have actually had 3 f150’s with the same complaint and every time it was that connector halfway disconnected. Seems to be a common issue. Idk if there was a bulletin or something that was performed that required this to be removed and they just didn’t plug them back in all the way, but definitely seems to be somewhat common.
A wiring harness connector decided to come loose inside my steering column to make the turn signal quit working after the Expedition was 15 years old. Lucky for me, it happened after I had moved the steering wheel adjustment, so that was the second place I looked, after making sure the bulbs were okay. Only one side was locked when they plugged in the connector at the factory in May, 2000. I still have it. That dude wasted a lot of your Thanksgiving not telling you exactly what happened. It is scary how complex these modern vehicles are. It is amazing that they don't break a lot more often. Imagine the computer program needed to control all that stuff!
And your truck is antique. The truck in the video is a decade old. Newer stuff is 10x worse. Where even to scan the faults you are locked out behind pay wall specific to that brand that year.
@@fastinradfordable Yep, it is a 2000 Expedition with 143,000 miles on a 4.6 liter 2valve engine. There is no road salt used near New Orleans, so the bottom is rust free. The silver paint & clearcoat look new, since it was always kept under cover. Parts are so cheap that I changed the rotors, ball joints, transmission filter, and rear oil seals about 5 years ago. I only drive about 900 miles a year & am 74, so if the computer survives, it might outlast me. It still has the original water pump, hoses, & AC compressor on it. They don't make them like that anymore. Whenever I get home I open the hood & release the pressure on the cooling system, since heat ages electronics and rubber. It raises the temperature in the garage about 2 degrees during the winter.
Hey Sherwood - thanks for showing the ugly. Really appreciate it. I like how you were looking for commonality. I sure wanted to find a common network junction and get the scope out and look at the data lines. Have a good thanksgiving dinner!
Any time I see these symptoms on these F150’s I go straight to those BCM connectors and check them. I have seen this MULTIPLE times over the years. I don’t see how those connectors come unlatched so easily but they do. I guess it’s from wild feet passengers kicking around over there. 😂
One ford assembly line worker leaves a connector unlatched, and 15 years later a truck is being towed and someone is going down rabbit holes like a Jack Russell Terrier. Go figure.
I've seen on another TH-cam channel, an F-150 same situation. It was the rear taillight with the radar in the module. Disconnect the taillight(s) and I bet it will act normally.
I bet someone else was in there checking a fuse found a blown fuse or not and when they put the cover back on they hit that lock just a little and over time hitting bumps in the road it came loose.
Perhaps the lever on the connector was never fully engaged in the first place (from the factory, or someone was snooping), and worked it's way loose. That connector moves a lot in and out as the lever moves, so connections should be quite sensitive to lever position. Also, I wonder if the kick panel was helping to keep the lever down and if a kick to the panel could then affect connection.
Almost jumped the gun and said fuel pump fuse relocate that fordbossme put out awhile ago, then heard you say no crank no start, and just heard the bubble burst lol.
County government fleet tech of 30 years here. I had this happen to us one time, same exact thing. Found that connector unplugged. I happened to look down at the floorboard over there and there were mud marks on the kick panel where it looked like they drug the side of their boots across the kick panel cover.

I used to disconnect the crash sensor on my business van whenever we went on vacation as a theft deterrent. It was an E350 and I thought IF someone loaded that up with tools from my shop they could get away with a lot.
I had this happen on a Ford escape and it was due to the accessory install guys installing a remote start and never replugging in the connector fully.
The flap on these connectors often have tension against the lock tab you press down, you've seen how you sometimes press it and it begins unlatching itself slightly. I could very well see the panel flexing against the pin with somebody's foot and 1, 100, 2000 miles later fully unlatching itself. Awesome find.

No auto technician is perfect, I'm glad you showed the bad part of the diagnosis!
Your shop is so clean... A clean shop is a good shop!
It's not just a shop its a operating theater for Automotive Diagnostics
Clean and also no distracting music.
I appreciate the diagnosis videos when you don’t know what is wrong, another great video Thanks
I love these kinds of videos where you explain the complaint, show the process and come to a solution. I'm subscribing just because of it.
As a previous Ford tech you are correct,once that engine starts Pats has no effect on an engine stalling…
This is why it is imperative to have a clear understanding of the clients concerns and as detailed as possible.
Technicians should assist the service writers and help train them to ask the right questions .
Communication is an EXCHANGE of ideas and information .
You have to remember the client knows something is wrong but generally doesn't know how to express it in terms that technicians understand .
Awesome video. It’s like working side-by-side with you and learning.

First step in any and all troubleshooting is a thorough visual inspection. Military taught me that and you'd be surprised how often that comes into play. Great job in your troubleshooting path though.
Seen a dude get dogged out (Ft Stewart) for not properly following sop diag... Dude (E-4) was doing push ups in the motor pool, lol.
I think it’s most likely that someone was in there earlier (perhaps even years earlier) and just didn’t make sure the connector was completely locked. With the cam mechanism on those connectors that mechanically (disconnects) pushes the connectors apart as it’s flipped open the vibrations can work them open when not locked.

Appreciate the honesty. Even having 30 years in mechanics I even need help from other techs to make my cars run. Not a big fan of the new generation

Guessing they had something down in the floorboard, like a bag or something, that found its way in there via wind or a foot and when it was removed it pulled on the latch.
I had one in the shop about 2 months ago with the same problem. I was going the same direction as you but accidentally bumped the connector checking fuses and got lucky
Kinda wonder if the cover was left off for a time then eventuality they put it back after everyone had been kicking at the harness
very good one,ask questions, but customers are not very dependable on giving good info. they make us go down rabbit holes all the time.
Apparently pulling off the road jarred the partially latched connector loose, perhaps hitting a pothole or the rough transition of the road and emergency lane. Good find!
I feel like I’m not a dumb ol bodyman. I was watching the video and when you had all of those faults for lost communication, in my head my first thought was something is unplugged. And holy shit when you found it I jumped up and said I KNEW IT! 😂. I take interior out all the time and when post scanning the vehicle it will be slap full of lost communication faults from unplugging a lot of connections. Well I’ll be damned I felt smart for second when it ended up being a plug.
I, for one, feel that it's great for him to go down the rabbit hole. I would have started someplace else. Another commenter stated that he would have started differently than I would have. We see Royalty went through different items and found an unhooked plug, whereas, Bisenbart found the same item, on another truck at another time!, if I understand. Now I know some of the easy things and places to check for, BEFORE I start down that rabbit hole!!
Good video I was fixed on the BCM from the beginning because of the key request signal
I’ve had this happen with a customer. It was a burned out airbag diagnostic module.
I have seen that same type of lever connector on Fords rattle loose and dissconnect, but never in that particular location, it's usually where a harness locator has come loose or broken and allowed the weight of the harness to bounce and work that lever loose. And it's generally on lifted trucks or slammed focus st.
Nice find. Enjoy watching your videos. Hope y'all had a great Thanksgiving.
I always think when things like that happen, I'm being set up. Someone is testing my honesty
Usually when the bureau gets a string of complaints about a shop or regional shops they might do a "sting" op. The best way to rule that out is if the problem is intermittent. They lose teeth in court if they hit you with an intermittent problem. This could have been a plant. It doesn't matter how the customer presents the problem. What you see is what you go on. This from a convo I had with an inspector in California some years ago but I think the logic still stands.
Open for updates on this.
Had a guy at work have a very similar thing happen with his F-150. He went to the dealer which was where he found out this is a common problem on those years.
At first I wasn’t sure based on the “it shut off while driving”, but after 10-20 minutes into the video, I started wondering if they gave you bad information. Then I also remembered the guy at work. I started saying look in the kick panel. Like you could hear me 😂 Low and behold you reset, get the correct info from the owner, and viola. Ended up at the right spot. I wonder if this issue is on identifix? Either way you got it, which is the end goal. Well done!
My guess is someone was disconnecting the plugs on that module before and when they reconnected, they didnt seat it all the way back on
Seen this on a Navigator, it had previously had a evaporator replaced by a shop.
I have been working on friends and family cars for years and would love to get better at troubleshooting starting with a OBD2
On a Toyota/Lexus, the transponder ring activates with key insertion. On most others, like Ford, the transponder ring activates with key rotation.
Those damn turkeys got in there and undid that connector! 🦃🤣
Awesome job as always.
good stuff, might be foot knocking on the panel and making the plug moved
I had the exact same thing happen, though, i caused it myself when I removed the blower motor. Put it all back together, and it wouldn't start. After an hour or so, I found the same connector loose just like that one.
someone has been in there, they just don't come undone. i work on a lot of the F150s, and Super Duty's, and mostly find OE splice and ground issue. we have the ones where the end user kicks the lower panel off and or is missing. not too many modules bad though, usually their feet cause the issue with connectors or wiring.
I've gone the wrong direction, from listen to the client. You listened to the client also. I don't think my clients (my kids) do it intentionally but they real know nothing about cars. One time my daughter told me she lost power steering at stop signs. She never told me, that the cars engine stopped too.
I have actually had 3 f150’s with the same complaint and every time it was that connector halfway disconnected. Seems to be a common issue. Idk if there was a bulletin or something that was performed that required this to be removed and they just didn’t plug them back in all the way, but definitely seems to be somewhat common.
A wiring harness connector decided to come loose inside my steering column to make the turn signal quit working after the Expedition was 15 years old. Lucky for me, it happened after I had moved the steering wheel adjustment, so that was the second place I looked, after making sure the bulbs were okay. Only one side was locked when they plugged in the connector at the factory in May, 2000. I still have it. That dude wasted a lot of your Thanksgiving not telling you exactly what happened. It is scary how complex these modern vehicles are. It is amazing that they don't break a lot more often. Imagine the computer program needed to control all that stuff!
And your truck is antique.
The truck in the video is a decade old.
Newer stuff is 10x worse.
Where even to scan the faults you are locked out behind pay wall specific to that brand that year.
@@fastinradfordable Yep, it is a 2000 Expedition with 143,000 miles on a 4.6 liter 2valve engine. There is no road salt used near New Orleans, so the bottom is rust free. The silver paint & clearcoat look new, since it was always kept under cover. Parts are so cheap that I changed the rotors, ball joints, transmission filter, and rear oil seals about 5 years ago. I only drive about 900 miles a year & am 74, so if the computer survives, it might outlast me. It still has the original water pump, hoses, & AC compressor on it. They don't make them like that anymore. Whenever I get home I open the hood & release the pressure on the cooling system, since heat ages electronics and rubber. It raises the temperature in the garage about 2 degrees during the winter.
Hey Sherwood - thanks for showing the ugly. Really appreciate it. I like how you were looking for commonality. I sure wanted to find a common network junction and get the scope out and look at the data lines. Have a good thanksgiving dinner!
Nice job and Happy Thanksgiving to you and your family.
At 35:10 it looks like the connector locking tab has holes in ittheft could be wired together to keep the locking tabs from separating.
I would prefer to use a small ty-rap to secure the connector.
I had a knock sensor code on a Subaru, found main engine harness loose, had engine out for head gaskets the year before
Any time I see these symptoms on these F150’s I go straight to those BCM connectors and check them. I have seen this MULTIPLE times over the years. I don’t see how those connectors come unlatched so easily but they do. I guess it’s from wild feet passengers kicking around over there. 😂
Nice job fellas
One ford assembly line worker leaves a connector unlatched, and 15 years later a truck is being towed and someone is going down rabbit holes like a Jack Russell Terrier. Go figure.
Ford has a TSB about this. Had one a few years ago same symptoms
.
Seen it many times it’s actually a common issue on these
I've seen on another TH-cam channel, an F-150 same situation. It was the rear taillight with the radar in the module. Disconnect the taillight(s) and I bet it will act normally.
I bet someone else was in there checking a fuse found a blown fuse or not and when they put the cover back on they hit that lock just a little and over time hitting bumps in the road it came loose.
Perhaps the lever on the connector was never fully engaged in the first place (from the factory, or someone was snooping), and worked it's way loose. That connector moves a lot in and out as the lever moves, so connections should be quite sensitive to lever position. Also, I wonder if the kick panel was helping to keep the lever down and if a kick to the panel could then affect connection.
Happy Belated Thanksgiving to y'all!
Cant remember if thats the year where the relays are common to go bad. Someone in the past probably was working on it and bumped the latch. Weird
No rabbit hole; as you said, you have to start somewhere. Pulling the radio, etc., only cost you 20 minutes.
Had same exact vehicle but a Tonka with the same concern and same fix
When you said every light lit up and this thing just shut off. I immediately pictured a ford in my mind. 😁
I was expecting a Chevy/GM.
Almost jumped the gun and said fuel pump fuse relocate that fordbossme put out awhile ago, then heard you say no crank no start, and just heard the bubble burst lol.
Great video.
