Some vehicles with modern ABS systems are extremely hard to completely get all air out of the system using the conventional bleeding procedures. In order to completely get all air out and get a stiff pedal again you need to activate the valves in the abs actuator in order to release the air. In this video I show you how to do it on a Jeep Cherokee. It is a very similar procedure for other vehicles.
I love my Autel. It has already paid for itself.
Good video.
What model do you have?

@@jalton9416 question can you program keys with mk808bt pro? And if not whats the immo for thanks
Thanks for the video. What is the point of having "brake bleed" option in the scan tool if this job needs to be done manually anyway?
Manual brake bleed doesn't get air out of the abs module. You need to activate the module with scan tool to allow trapped air to exit.
@@themodernmechanic428 It almost feels like doing the same thing twice. Instead of doing this 2 times, can I just use scan tool and do as it instructs, will that help bleed brakes and take care of air in the system?
Depending how much air is trapped in the system most likely you will be fine doing the scan tool method. Every job is different.
Do you need a second person to hold the break pedal down after the test starts in order to crack bleeder?
Man I used another scan tool but it had me open the front right 7 times lol I gave up how long is it gonna do it?
I have the Autel Maxicheck Pro which bleeds my brakes on a Lexus GS300, saves a trip to the dealers.
Nice! Saves you a lot of $$$
Do you have a extremely long cord to connect to the obd port and go to each wheel or what? And I see most say to hold down the brake pedal while performing the test. How do you do that and be under the vehicle as well to loosen bleeder valve?
The OBD VCI connection is wireless and I have a pedal depressor on the pedal. You can also use a piece or wood (2x4) or something similar
@@themodernmechanic428 So you never have to let up on the pedal during bleed, in between the opening and closing of the bleeder valve? I don't understand. Thanks. I guess as long as the hose doesn't come off the bleeder valve you're okay then, right? Sounds a bit risky, to me, esp. if that rubber hose slips off the bleeder when you're tightening and loosening it.
thank you sir!!! i was not taught this at my college
That’s awesome! Which college?
@@themodernmechanic428 delta college.
It seems the industry just expects you to know how to use scanners and oscillioscopes automatically. Seeing examples like this really helps me get a better understanding of what textbooks are saying.
Question
I replaced my rear brake Calipers and now my rear brake pistons won’t compress can it be I have air in the abs do so can this scan tool bleed my breaks on a 1999 Honda Accord
I have ms906bt I was trying to bleed my mazda cx5 but my scanner doesnt have this function for my car.
HI DO YOU DO THIS WITH THE CAR OFF OR RUNNING OR JUST THE IGNITION OPEN THANK YOU
I guess u better start the engine if your battery not so good,abs motor running with 14 volt.
Do i need to use a scan tool to brake every car?
Which Autel Scanner did you use? What year Jeep is it that you are working on. I have an 2008 Wrangler that I need to purge the are from the ABS. Not sure if it can be done with a scanner on that year Jeep. Thanks
I’m using an autel maxysis scanner. And I’m working on a 2014 Jeep Wrangler. I’m pretty sure it can be done on a 2008. Pretty much any autel scanner will have this function. Good luck
Thank very much for the reply. Great video on the procedure. I didn't know the process you showed was available.
I have a 2014 JK i ordered the LAUNCH CRP 479 from.Amazon, the seller said that supports auto bleed on my jeep but it doesn't, I'm returning it tomorrow. Can you recommend me a scanner that does? Thank you!
Good Video
Hi I have a 2010 Ford Escape that has no brake power at all. My husband bleed it manually from the calibers and he also did a auto bleed using the Autel maxipro. We have been working on this truck for the past three days and still no brakes.
Did you loose brakes all of a sudden or what is the reason you needed to bleed the system? Ford abs is very tricky, you need to bleed the master cylinder first, the. You manual/pressure bleed the system and finally do the auto bleed with the scanner. Repeat manual and auto bleed until you get a firm pedal
Also for others reading this, pay attention to how fast the fluid comes out, if everything is sealed, it should look similarly fast like when he bled the front passenger wheel 1:28. If it is significantly slower, there may be a leak elsewhere…
I know this was three years ago, but did this happen after new calipers were installed? If so, I bet they were installed on the wrong sides of the car.
the MixiCom MK080 can do ABS bleeding on a Chevrolet Astro 98 AWD ??
Mercdes benz E350cdi model 211226..year 2003
It says keep brake pedal depressed. You have someone holding the pedal while you do it or something laying on the pedal?
I had a pedal depressor on it. You can use a 2x4 or something similar against the seat, works just as well
@@themodernmechanic428 Thanks
What about cars with dual bleeders per caliper ?
Bleeding without press brake ?
can i bleed it by hard connecting its relay?
I just purchased Autel Maxicheck Pro and it does have the AUTOBLEED feature on it. So you bled the brakes before the scan, during the scan and after the scan?
Mark J I typically do the auto bleed with the scanner first, this primes the abs module. Then I do a manual bleed after. Either by pumping (2 person job) or vaccum bleed. This always gets me good results.
@@themodernmechanic428
Thanks brother
@@themodernmechanic428
I did the AUTOBLEED and then I did a manual bleed. I did the AUTOBLEED again and now my pedal feels a little better. Not as loose as before. Do you think I should keep doing AUTOBLEED and manual bleed until pedal feels better? I have been doing this for about 2 hours, me and the wife. I am so tempted to buy a master cylinder but I want to AUTOBLEED to see. I read from a Chevy Tech that in my 2008 Impala, you CAN NOT do RR, LR, RF, LF. It has to be performed diagonally, RR, LF, LR, RF. Crazy right?
Mark J that is crazy. I’ve never heard of bleeding diagonally. Are you getting good pressure from all 4 bleeder screws? I would try autobleed and manual bleed one last time but I’d pedal doesn’t get any better you might have a bad master cylinder like you mentioned. Also, what is the reason you are bleeding the car? Did you do any work to the brake system or are you doing it because the pedal got soft for no reason?
@@themodernmechanic428
You mean good pressure like the brake fluid flows clean - without bubbles, yes. Everything looks good to me. I was bleeding because I was doing a procedure that I thought would help my sporadic hard pedal - check this out below
th-cam.com/video/273pA6VymgM/w-d-xo.html
My car was making this hard hissing noise, a noise that was very noticeable inside the car. It triggered a check engine light that read a lean condition, P0171. Everything that the guy discussed in the video was what I was experiencing. I bought that rubber piece he talked about in the video, I took a chance because I had a check engine that read a lean condition and plus I need to get my emissions done and they are not going to pass me with a check engine light. That's the whole story. When I reinstalled the master cylinder, I bled the lines on the master cylinder first - spongy pedal. That's when I realized that its a lot more I need to do.
Thanks for the video. Does the Autel only bleed the pump and the right side of the truck? That's what my PC based scanner does and I'm confused why the procedure does not bleed the left side.
This procedure basically bleeds the abs module only therefore it only opens up front and rear valves not necessary left and right. You should still manually bleed left side if you opened up that side.
I don't get it,,If you still need the pedal to be pressed ,Then the scan tool doesn't really make any difference.
It’s bleeding the ABS module.
Pressing the pedal alone doesn’t activate the abs. So the residual fluid in the module will stay in there. The scan tool activates the abs module s when you replace brake fluid you get all the old fluid out.
If you read the first part of the video, it stated that some vehicles require abs module to be bleed after doing a manual brake bleed.
How much does it cost to have a mechanic or a dealer do it for you? Just curious about much I'm gonna save cause I ordered a maxicheck pro scanner for $216 plus tax I thought it b cheaper than taking it to a shop plus I get a new scanner for other jobs later
In my area ( Southern California ) just to bleed the brakes would be about $150 - $200 from dealer. That autel scanner is a great investment.
Can this be done with the cheaper Autel MaxiCheck Pro?
I’m not familiar with the maxicheck models but you can find that out on their website.
Not have this in autel maxicheck pro
The Autel Maxi AP200 can do auto brake bleed on the ABS module to get air out of the system. It is limited to certain Vehicles though. I purchased it for my 2007 Toyota Tacoma and it would not perform this action
@@mech4061 crap I hope it works on my 2010 Taurus cause I'm paying $216 for a maxicheck pro
I have the one that you use your smartphone with and it has that feature on it. Works just like the handheld model. I purchased it from Walmart for about $59 but it works great because everything I want it to and more I was even able to make a new key fob and program it with with my phone. The instructions are a little bit vague as far as help but other than that I love it
nice but still a two person job since brake pedal must be pressed at all times yes...
I tried this scanner on my 2017 zl1. The pump only work on front right and rear wheels. Dont know why!
Using the scanner to bleed the brakes is mostly necessary to get the air out of the ABS pump and on some vehicles it will only activate one side on the front and one on the rear. You should still bleed all 4 corners the old fashioned way with a vacuum or manually, however after using the scanner that should be very quick and easy.
@@themodernmechanic428 i already did bleed the system , but i used the scan tool after manual pressure bleeding. Not be4.
Ok yes, that’s the correct way. The scanner will only do one side in the front and one in the rear. I have only seen it do all 4 corners on some Chrysler vehicles.
@@themodernmechanic428 If you haven't done it already. You should redo this video and make sure all the questions hear are answered in the new video.
how about a 2002 Jeep Grand Cherokee
Sorry for dumb question. How come you bleed your abs manually first?
Not a dumb question at all, I asked the same thing when I read the bleeding procedure on the repair manual. It is not explained on the manual but after bleeding several cars this way I came to the conclusion that the abs pump needs to be primed first in order to be able to pump fluid and the way you prime it is by manually pumping the pedal. Hope this answers your question. Please subscribe and like the video.
Does the engine have to be running I tried this and it didn’t work.
Socomcasniper no it doesn’t have to be running. Did it let you go through the process at all? What exactly is not working?
The automatik transmisin doesnt word..and the red light of brake is on..
That car looks entirely way too clean underneath
Do you have to keep refilling the reservoir?
Yes, you should make sure the fluid in the acceptable range while bleeding brakes.
I started to do the procedure and then when it told me to open up the right front then I thought how can I do that when I have my foot on the brake that's the part that I don't understand after they tell you to keep your foot on the brake obviously you need to people or do you just let off go open it up put your foot back on the break and then hit okay. I know it seems dumb but I just don't understand some of the instructions and by the way I didn't see any instructions for that horse I don't have the real good model I just have the one that uses my phone but it still has that procedure and it seemed to work the initial procedure started and it did it and then it went to the part where you start open up each one. But then I thought I must need somebody and I stopped
Rick Hartley you can put some kind of stick in between the seat and pedal to hold it pressed. However I’ve done it without pressing the pedal and it works as well, but you might have to do the procedure a few times. It’s easier to just find a stick to hold the pedal pushed.
@@themodernmechanic428 and the second the pump activates, the pedal pressure is gone, the stick falls out and your back to square 1
What happened to your voice, video stuck with no voice. Also do you need to buy some clear hose, a black hose will not show you fluid movement or air bubbles coming out.
I’m having a tough time bleeding the brake system on a 2012 fusion.. I tried it with both my scan tools (autel ts608 & snap on apollo d8) but I still can’t get the pedal to come up :/
It sucks I shouldn’t of got this job.. customer already replaced module and master cyl. brake booster and a bunch of other things.. but the rear brakes are almost down the the metal smh 🤦♂️..
sighs.. I guess I’ll see how it goes tomorrow with it..
Any tips or advice???
Bleed all 4 corners with a vacuum bleeder. Then use the scanner and bleed it with the scan function. Then one more time with a vacuum bleeder. That should do it.
By bleeding it with the vaccum bleeder first it primes the abs module so that when you use the scanner it will have pressure.
Wow that’s true.. I did vacuum bleed but I didn’t try it with the scanner afterwards.. gonna try it in the morning 👍 thanks
So did it work? Where you able to bleed it?
The Modern Mechanic nah man I wasn’t able to..
Fluid wouldn’t come out of the passenger side only the driver side..
And the customer had already messed with it too much they replaced modules and what not and idk if they did it right so I just let it go :/

The whole mechanic industry needs revision. The whole book time time is a rip off for techs and customers, warranty time is a fraction of the tech time. I was quotes $250 bucks to bleed the brakes, with these tablets its literally 20 min. The tech made $30 bucks dealer spent $4 on fluid ill be nice and say 20% on overhead ( insurance, building, license, tax etc etc.) ech has to buy all the tools yet the dealer pockets $170 do they really a $170 in value, Dont forget the $65 shop fee for the 2 rags, can of brake clean and $.25 worth of siliglide
Clear tubing is only way i will ever bleed...
So these scan tools that bleed brakes don't actually do shit...lol. If someone is pressing the brake pedal anyway why use one?
Pumping the pedal alone doesn’t get all the air out of the abs pump. You need this scanner to activate the pump and open up the valves otherwise you will never get a firm brake pedal. I had a Chrysler 300 where 3 different mechanics tried bleeding it and they couldn’t get it, they didn’t know what was wrong with the car, until it came to me and I used the scanner and took me 10 minutes to get the brake pedal nice and firm.
@@themodernmechanic428 i think is the problem i have with my camaro 2013 ss i did it not using scan tool and it feel weird like still air in the lines hope i get my autel scan tool next month ... good video thanks
@@JOSERGMMXX yes a Camaro requires the scan tool to completely bleed the abs system. You will love the autel.
so essentially this is a three person job, one to man the brake pedal, one to open all the bleeders and one to watch the master cylinder so it doesnt run too low
One person job if you’re smart enough. No need to pump so you can just put a brake pedal depress tool or a 2x4 against the seat. you open up the bleeder valves yourself “ do one at a time “ master cylinder shouldn’t go empty but you can go back up and top it off at after you do 2 wheels. It’s definitely not a 3 person job
Use a Motive Power Bleeder. Fill it with 2 quarts of brake fluid, pump to 15psi and bleed away. You'll never use all 2 quarts unless you do something wrong so your brake reservoir will never go dry.
Not werth watching, get rid of the glare, than voacally guide through the process
So you do this to every nipple
