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

[@EATSLEEPFARM]

Aint that the truth!!

[@johnmeyer6537]

An emergency brake is a hand lever you can use to slow the car down when your hydraulic brakes fail. Even the foot control parking brake is not an emergency brake unless you tie the release back. I have had to do it and it sucks. Why they make just parking brakes now is beyond me. If you live where it freezes you can't use them anyway or they can freeze up. Plus you can't do power slides. he he

[@neverstoplearning382]

Another great case study. Take care.

[@Mr2004MCSS]

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

[@Hybriddiag]

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

[@cullenmiller8170]

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.

[@fredautos]

Then the explanation goes this way,. We are Just pàrts Changers!

[@spirokattan3655]

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

[@advancedleveldiagnostics]

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

[@paulburroughs1313]

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

[@522001pd]

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

[@KlassikKarvideo]

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

[@waqasazmat81]

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!

[@MaicSalazarDiagnostics]

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!!

[@DependableAutoTruck]

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

[@autodiagyt]

Yeah I might do that. I use 1 tool for 99% of all connectors lol

[@DependableAutoTruck]

@@autodiagyt not sure why I have so much trouble have ruined a couple trying to get out. Bought a master pin out tool kit looks so simple on KZbin to give me so much trouble thanks

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

[@nicksrcadventures6831]

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

[@DependableAutoTruck]

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

[@modernageauto]

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

[@autodiagyt]

It comes in handy

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

[@paulspeller968]

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 👍

[@martinarrieta248]

Grasias

[@edwinlomonaco6754]

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.

[@lovetolearn5253]

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.

[@autodiagyt]

That’s cool!

[@bobbybrown8926]

nice fix jake.

[@JBlake-moon-shdo]

Great diag Jake. As always.

[@alrifainidal]

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

Excellent diag

[@timothycanfora8491]

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

[@timothycanfora8491]

Oh and what looks good and what it looks like when it's bad

[@GreyRockOne]

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

[@amundsen575]

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

[@ritchieschofield1185]

A great NPR fix. Nice find!

Great job Bob :)

[@WadnerFenelus-o8x]

[@johnthompson6960]

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.

[@autodiagyt]

Lol matco uses the same launch software.

[@hnd2893]

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!

[@hnd2893]

Forgot, on some EPS issues, they'll generate random DTCs, had one recently the coded for a WSS, live data showed a wheel speed of 100-mph, with the car sittin' still. Repaired the EPS motor circuit issue, cleared the DTC and then the recalibration went smoothly. These newer cars and their Smarty functions are gettin' dumber by the day.

[@windward2818]

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.

[@magid5441]

Problem love by genius

[@aymenmohamed1134]

Awesome

[@DependableAutoTruck]

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

[@scotts4125]

I have been an automotive locksmith since the 80's. I have seen a lot less problems with the cables for locks and latches vs the old rods and clips. It's the electronics that mostly fail. The old metal clips would rust out even in Florida and the plastic rod clips would get brittle and break. Once in a while you see a stretched cable but that's pretty rare. The newer cars are also actually easier to open than the old ones but that probably has more to do with the evolution of lockout tools. Some of the older cars we rarely see give my guys some trouble. As far as newer vehicles some Ford trucks are the biggest PITA to open. Old H1 Hummer is a PITA, 08-13 Honda's the flipper pushes in instead of out, but overall it's the Ford trucks and large Transit van. ughhhh

[@jgeorges3061]

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.

[@charliemagoo7943]

Here🎉

[@spelunkerd]

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.

[@autodiagyt]

Possibly I’m not sure. I can’t think why they would test there. It’s common for these motors to fail and this is the first time I’ve had to go further then testing at the plug in the wheel well.

[@joshuamullins5091]

Hey awesome video. I'm having a similar problem. However; I get long engage process ( that doesn't engage) on the right. The left has a short wind and engaging fine. I'm not sure what's up? I'll have to try this tomorrow. I feel like it's the actual actuator but I'm not sure at this point. Thoughts? - NG POG- from VA.

[@paulspooner-q6k]

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

[@jimburgess9205]

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

[@octaviocarrillo5954]

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

[@autodiagyt]

It’s a separate line on the invoice. The diag tells me where the problem is, the fix is a separate charge because it could be a simple terminal retention, all the way to connector replacement. Find the issue then discuss options to fix it.

[@luismartinez1824]

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

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

[@autodiagyt]

It needs calibrated yes. It needs to learn it's position.

[@BesprovolkiSvias]

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.

[@autodiagyt]

You will never get. Them perfectly scaled horizontally but if you get a good stable idle I just let it run and get a lot of pages and then scroll through the pages and find one that best lines up with my reference. This method is best for comparing 1 full cylinder cycle like 1 compression stroke to the next. You can usually get 1 cycle lined up pretty well with the others as you seen on that video I got 4 in cylinder waveforms that almost perfectly match each other and it’s because I was using short time base to get what I needed all in 1 page and nothing else with a good reliable trigger. Keep in mind you can also get measurements in degrees with pico when you setup the phase rulers.
