Ford Fusion Parking Brake Malfuction 

Emergency brakes should never have any wires or actuators between the driver and the wheels... ;)

Now we just want to hear the explanation from the shop to their customer on why the module had to be replaced twice and it needed a new parking brake motor. This is why I want to recreate the fault before replacing a part.

Very good diagnosis. It's hard to believe that all of those parts were thrown at it on what is a simple circuit.

Great job, Thanks for sharing! My favorite diags are with a test light and a diagram.

Great diag my friend, this proves how important is to check wiring integrity. But at the end of the day, what do most costumers cry or complain more than anything? Yes, when we need more diag time! Well do not cry when you spent thousands on something we could have repair with a wire terminal and some diag time!!

So glad you used the Deox-it. Regular contact cleaner is pretty much useless from my experience. Great video BTW.

Great diag..sir its always understanding circuit lay out to find the issue..people love to throw parts canon 😀..i had a ford ranger 2016 abs issue right rear wheel erratic reading imagine its been changed abs module wheel bearing and sensor and it was just case of corroded wire near frame line..thx for the great info sir

Nice, a good refresher on a V R and I basic ohms law and voltage drops. Love the fact you use test bulbs makes it so easy to understand what is happening. Thanks as always!

Great find, my stacking banana plugs have now arrived so I’m making a set of those test bulbs for sure!

one of the seems odd i have problem unpinning and usually if i get them out can tighten but getting out is a real problem i have bought several kits would for me be a great video on the best ways to unpin different connectors and tightnening

Great step by step diag approach and explanation. Thank you Jake!

Your vid's are really easy to follow, great job. Keep up your good work.

Parts cannon for a lose connection. Good job, Jake!

Ahhhh vary well done~Nothing wrong with playing it forward~Big thanks 🚘

Great video, my car did this to me yesterday. Same exact scenario actually, same side and all lol. Thank you for helping pinpoint the issue with this. Local dealership didn't have one in stock so I gotta wait for it to come in. In the meantime I cut out the bad section and soldered in a new piece as temporary fix to at least get the car to quit yelling at me. I couldn't take the nonstop dinging because it thought the brake was engaged hahaha. Surprisingly it worked and I was even able to clear the codes without a scanner by cycling the parking brake. It automatically recalibrated when engaged and cleared the codes

Some customers live on very bumpy roads, and the whole car experiences some rather ridiculous vibration modes. But, you may ask, if the connector is shaken how come all the pins are not loose? It is because the vibration effects the most rigid (transmitted to) structure, which are the large heavy gauge wires. This is the risk of using a mixed pin size connector (connectors having both small and large gauge pin connections). The larger gauge wires are basically acting as the vibration strain relief for the entire mass of the connector. My guess is if there was dedicated 2 pin power connector to the motor and another connector for everything else, that (unless water intrusion was also a problem) the system would not have failed. If we focus on the repair, it is clear after fixing the pin tension problem and cleaning the pins, that we must strain relief the kick panel connectors beyond what the factory provided with the Christmas trees. You must find a way to hold the connectors and harness tight to the vehicle and tie wrap the wires together as close as possible to the connector. Make all the wires move as one. We should also look for signs of water intrusion into the kick panel area. Water is getting to the harness and running down the wire into the connector. If you don't have time then reposition the harnesses so the water cannot wick down into the connector pins due to gravity. The video is rather interesting in that the previous shop (not sure what to call it) could not fix this simple problem. The codes indicated what was wrong and a simple voltage test proved on open or high resistance connection to the motor. Yet they replaced the motor and two ABS modules, just incredibly brain dead.

i like the way i calibrate the ones on my 1994 ram 2500 4wd just takes 1/2" wrench no scanner or wires to worry about but the new way is somehow better yep

Next time you are slow maybe a scope class. Such as how to hook up to test different components and things like time bases and whatnot. I have been watching your videos for about a year but maybe like a Playlist of the most common setups

great video thanks so much for taking the time to share hopefully can remember when i need it

Love to see this. I made myself one of those dual filament test lights after watching some of your previous videos. Previously only had pre-fab test lights and a 5 amp headlight . Nice to have various loads to try to match the circuit

Big brain jake did it again

I dont know if you remember but a few weeks back i asked if you every came across a cam shaft reluctor wheel becoming magnetized. It ended up being the reluctor wheel. Thats the first time I've seen that actually happen. The tech took a high power magnet and hit the reluctor wheel by accident. By him hitting it part of the wheel was magnetized. What a great find.

oh yes sir ,fords seem to make there terminals out of cheese if i had a pound for every time i have seen a spread pin i would be able to retire 🤣🤣🤣 due diligence is a must for sure just because it don’t work don’t mean its a bad part and like you have said many times just because your metre says voltage it don’t mean it will carry current. excellent job my friend. and it don’t take long to run that type of test to confirm a good or bad circuit 👍

I really enjoy your videos. Looking forward to the next.

Superb job, Jake!

great video , good job Jake, looks pretty hot where you are 🤩

I'm guessing there were two problems in this car. The first was a bad motor or bad module, but while the techs were doing testing they spread the terminals of the connector, or maybe misaligned the connector so the pin was bent. Replacing the good component didn't fix the new secondary problem. Then they gave up in frustration. It's more evidence to support careful step wise diagnostics, and going back to retest when things aren't as they seem.

Although this is job security for you and I enjoy watching. Whatever shop doesn't have a tech that can figure this out maybe needs to re-evaluate.

Good video with good diagnostic and troubleshooting 👍

nice fix jake.

Nice work! I'd expect an outside connector, not an inside one, wow. You barely got your hands dirty.

Great fixed, no pàrts required!

Water or heat = terminal problems. Good diag and fix.

a parking brake cable and lever has worked for over 100 years and some how we need a motorized one!

Thanx Jake..another light bulb moment.. You rock~!

Thanks for sharing Jake. Once again, nice use of your test lights.

Thank you for your time ❤❤❤❤

Cool diag Jake thanks for sharing this one.

Good job 👍

That is really awesome! Great job. I hope you make videos about diagnosing issues with hybrid cars.

Another good one Jake, thanks for sharing. First class.

Your diagnostic skills are quite impressive. Video presentation is also first rate. How does Topdon/Launch work so well for so little money? Snap-On, Matco etc are done, easily eaten by the Chinese.

So I have a 2014 SE and mine just came on and I’m on yt to try and figure out why it came on when I’ve barely had it for a year

Grasias

DEOXIT, never heard of the stuff, gonna get me some. I've been using a lot of Stablant-22 lately, especially on connector pins that are half the width of a GAH (gnats ass hair ) That is a unit of measure where I'm from 🤪 Some of these EPB systems need to see a brake fluid pressure reference value, pump the pedal KOEO, cycle the key ON/OFF, then try the EPB recalibration function. Looks like you got some work, hope the phone keeps ringing!

NIce! Using test bulbs makes it easier to understand. Did you make your own test bulbs with banana plugs?

Jake, AWESOME approach and thought process are you trained with hybrid or electric cars if yes hope will see those cars in ur bay soon and learn new things as always thanks for sharing.

Great diag Jake. As always.

A great NPR fix. Nice find!

Good

do you see any advantage to so called improvements like from a rod to open and lock doors to electric, like window switch used to reverse politarity for up and down to a module to do it, electric parking brake instead of a cable that lasted life of vehicle at least in the south, electric t-body vs cable operated. new vehicle cannnot run without a radio , some f-150 wont shut off have to unplug ABS module to get to shut off why would ABS have anything to do with the running of the engine. why would the radio have anything to do with brakes or engine running or speedometer working radios were designed to play music thats all they need to do

Great job Bob :)

Problem love by genius

Hey jake what is that tool or etc you put by the back wheel so you could hear that noise . That is cool you can hear all types of noise

Here🎉

if it was a used car lot that would explain it, if it was a shop then someone is not trained. scanner danner is trying to address these issues as well. like this was just basic testing , but i see this alot and dont know how this is gona change. im my area the techs dont wont to gather and learn from each other. i dont know why . i have asked several guys about getting together, but no response, it appears we are our on enemy. if i was close to you i would love to hang out once a month just to help each other. have you ever tried to get any techs together in your area for collaboration . let me know if you have or not . curious. i sometimes wonder that they think they will give away their secrets they dont wont someone else to know. i love giving information to people ,their are plenty of cars with complicated problems for us all

I’d love to see how you use a pico scope and how it helps you diagnose problems.

How did you make those test lights with the back probes those are handy i can never get mine to stay together good when testing

Good stuff man! Question, do you charge separate for the connector repair or just roll it into the diag fee?

I really want to get some test light bulbs like the ones you have. Are those custom-made or did you buy them? Please lmk thanks

If you're slow I'm sure that you're viewers including myself would like to know how you got stated and maybe a tutorial on multi meters

Awesome

❤❤❤

In recent previous video(s) you mentioned that oscilloscope's (PicoScope) "Reference" virtual channels can be used to multiply number of channels by adding saved waveforms (by combining waveform files into one display, using "Reference channels" function" of PicoScope). But how do you align two signals HORIZONTALLY if say, idle RPM is about 600 RPM on one scan of crank sensor's waveform, and idle RPM is about 650 RPM during second scan of crank signal? First will appear a little "stretched" horizontally: how do I "shrink" it horizontally to align this crank signal scan with second crank signal scan? (Note: vertical "stretch", aka "scaling" is easily can be found on PicoScope, but I cannot find horizontal scaling function. I only see function that can MOVE signal horizontally, called "delay". But I need to "stretch" the signal or "shrink" it along x-axis, horizontally). Without this, "Reference" function is useless.

hello sir , ask a question ? where did you purchase those back probes? and do you like and have trouble piecing the wire with them. I ask because I bought some and I have trouble piecing

Dam good job Jake soak them good😂.sam

Excellent, by the way, how much do you charge for a job like that?

Where can I get that test light mate? great video!

What are the test leads brand name you use for your homemade test light

So if I get a motor from the junkyard I still have to program it??

Shudda went n gone to the Electron Doctor first 😃😃👍👍

probably needed codes cleared before it can calibrate its self

What if that light just stays on. ?

Where will these bulbs be found?

Just hard wire the wires around the connector then you dont have to fix connector?🤔

Another expensive lesson!

How does the freaking connector terminal get spread apart, all by itself 🤔

Ford needs to use wire nuts 😢.

its really sad that a pretty simple issue like this was misdiagnosed.its no wonder people dont trust shops.i think that every body wants a super quick diag and fix and alot of times itll bite you.

Good

Good job 👍
