How to replace abs module assembly

[@joev1779]

You did a great job with this video!

[@richierock1300]

Thank you

[@jonnybgood8348]

Same problem with my wifes 08 thank you for your video Sir

[@elivoorhees7075]

This makes me a lot more confident about buying a ls460 tomorrow… I really love the car but this issue was always scary to me

[@youngsaki]

internal leaking Brake Actuators and leaking coolant valley are common on ls460

[@robertsumner9980]

For anyone else attempting this on your own, I sent the part to a company called UpFix. Took them two weeks to fix all the seals and replace the pump. They cleaned it up so well it looked new when returned to me. Cost me $450 as opposed to the $1300/new or $800-900/used. The only downside I had to wait 2.5 weeks to get the part back.

[@richierock1300]

Sounds good hope it works out for you

[@johndavid7637]

That's awesome, great to hear that's working well for you. By the way what symptoms did your car have for you to service the brake actuator?

[@richierock1300]

@@johndavid7637 gosh been awhile pretty sure shorted out power code

[@johndavid7637]

Hi Robert Sumner I'm glad you got your unit repaired. What symptoms/codes did you get for you to decide to change the actuator. I'm also thinking of sending the unit out for repair over the summer time. Thanks.

[@jayelking2856]

was the car okay not having the brake wires and stuff for 2 weeks?

[@hsmelltherock]

Brake code... is that the vsc/trac control light off (squiggly lines w car) that shows on dash?

[@MrNewcarscott]

I Will for sure. Thanks

[@MrNewcarscott]

Wow. Thats just great Great video. You are the man. I have the same thing going. I could handle this repair. Especially with your video. BTW how much was your used unit? Thanks scott

[@richierock1300]

I paid 900.00 ,just take your time

[@benlarson756]

Can you go further in depth on how to do the gravity bleed? Currently attempting to now and it would help! Like how long you waited for the fluid to come out.

[@richierock1300]

If it’s not coming out after a bit have someone push the pedal down and snug up the line before release the pedal do that a couple times see if it starts on its own otherwise you have to bleed like that

[@johndavid7637]

Great video! My 08 ls460's brakes are not as responsive and strong as my 06 ls430. When you replaced the actuator. How did the brakes feel? Was the braking responsiveness restored? After changing the actuator do you think the brakes are strong on this car?

[@richierock1300]

Brake pedal felt normal just make sure there’s no air in system

[@critic2783]

Hi, Can you share where you got your replacement part from?. I need the same job done & cant afford the dealer's pricing. And did that ABS module include the brake pump motor assembly & brake actuator inside of it?. Like, is it all one whole part or 3 individual pieces?. I'm trying to understand.

[@richierock1300]

eBay make sure to have your vin # to give to them to see if compatible

[@Kurt-xn4sy]

Doing this next Monday. so after install all the dashlights disappeared or did you erase them with scanner and they have not come back on? Thank you for the video.

[@richierock1300]

Cleared codes with scanner and it was a success

[@jovannycecilio2068]

Switched out my old one for a LKQ one. Parts and labor I’m about 800 in and my light comes back on has your came back on ?

[@richierock1300]

No sir

[@Sclassmercedes]

So what’s involve in the bleeding? If it’s not done correctly is the pedal still hard

[@richierock1300]

They say need a scanner to activate the abs solenoids well the way I did it pretty much the same way I do all the abs units start at the master and work your way down from there get someone to push the pedal for you slot faster that way just take your time it will be fine

[@isaiahbarnett6303]

Thinking about doing this myself after seeing the video, got quoted 2500 for this

[@richierock1300]

Just make sure you give them the vin# when buying on line to make it compatible

[@ryannrjohnson]

Usually it’s just the attached accumulator that goes bad, I took mine to the dealer cause my accumulator went bad and he told me the tech said no I needed the module and it would cost $3000. I told him it’s the accumulator but if that fixes the problem then yes I agree to pay that. Tech changed it and found out I was right. I had a loaner car for a month through all of this process. Most techs just throw parts at vehicles now because either they don’t know or the dealership won’t pay the worth of good mechanics anymore.

[@MrNewcarscott]

I guess the one thing that confuses me is that how you got away with not using the lexus "special tool" to bleed it. Some guys seem to say its necessary.

[@richierock1300]

Gravity bleed to the unit with the lines connected but loose and then pushed pedal to floor to help get air out of master then tightened and did it the same way on the unit , take your time , remember master first unit second

[@Rexbraiku]

There is no special tool needed its total bs

[@kevinhayles3311]

Hey Great Video!!! I have a 2011 Lexus LS 460 Rear Wheel Drive I was told by by my dealership I needed a new ABS module so I purchased a used one for $645 and had it put it in for another 1180. Now the mechanic that put it in is telling me that they cannot get the rear breaks to bleed, but the front did bleed, and they think I purchased module with a bad pump. They want me to send the module back, purchase a new one and charge me an additional $800 to put another in. After watching your video I dont think they know what there doing. Can you please advise me on how to bleed the the rear brakes? Or what you think my next step should be?

[@richierock1300]

@@kevinhayles3311 start bleeding close to the master and work your way back to the rears . Use a pressure bleeder if you have one or make one from a cooling system pressure pump and get a cap that fits the reservoir and fabricate a fitting on top and pump some pressure on top of the fluid to force it threw a vacuum type at bleeder fo not work as good

[@Domthedon33]

Great video I do have a question if I replace the whole unit you pulled out would there be any reprogramming needed?

[@richierock1300]

They say but mine was used so it might of just used the programming from the old vehicle I’m sure if it’s a remanufactured one it would need to be , try it have to program it anyway

[@Domthedon33]

[@123lolshto]

@@Domthedon33 do you remember what codes you had? and did you buy the whole assembly (pump,actuator, module, accumulator)?

[@shaylee2b]

If the ABS is rebuild is there any need for a new code?

[@richierock1300]

??

[@stuttgart931]

You did not have to get the module programmed to make it work? That is the issue I keep hearing about. When replacing this unit, you have to program the module to the specific car that it is being installed on... Is that not correct?

[@richierock1300]

Well I didn’t I worked tight off the bat and still is I guess I got lucky hopefully you will too

[@user-dp3cb8lm2q]

hello, tell me why I can't pump the brake fluid of the inner tubes of the abs unit?

[@richierock1300]

You might have cycle the key to get so pressure in them otherwise need to bleed before them

[@user-dp3cb8lm2q]

from the main brake cylinder , the pressure comes from 2 tubes , and from 1 tube of the front wheel and from 1 tube of the rear does not pump

[@richierock1300]

Check your power supply fuses you don’t hear the motor or anything

[@Sclassmercedes]

@@richierock1300 I do hear the motor

[@Sclassmercedes]

So if it’s bleed correctly wouldnt the abs code needs to be clear so the pedal will get soft ?

[@richierock1300]

Ok if you can still double check the maxi fuse and then try bleeding it again , leave key on and open a line see if anything comes out

Hello this greate video and very understandable explain, thnak you very much, If you can help me I have DTC c1391(Abnormal Leak in Accumulator) Lexus CT200h what is broken, Vaccum Pump or Master Cylinder Assembly or both parts need to replace?

I’d get a used one or a rebuilt on complete with master

[@user-vn8ip2sl4l]

it is necessary to replace 2 parts?

[@richierock1300]

No mainly do the module assembly

[@robertsumner9980]

The gravity bleed is what is confusing. did you bleed the brakes by yourself? You mention pumping the brakes with the ABS lines 1/8 turned open...how did you not get air in the system?

[@richierock1300]

I loosened like a half turn push to the floor install a long bar to hold pedal down then tighten the Le and release the bar and repeat a bunch of times to help bleed master also loosen up a little and let them drop too start at top work your way down sometimes easier with someone pushing pedal you open then push down and hold and you tighten then release pedal and loosen and push pedal

[@robertsumner9980]

Once you bleed master and confirm no air in ABS Module, then you need to bleed each line going to the calipers, right? This way you finish bleeding the entire system, correct? You don’t mention this in video.

[@richierock1300]

@@robertsumner9980 well your right there , I got lucking and didn’t get any air in the system kinda hard to explain but if you have fluid in a hose open on top and closed at bottom the fluid won’t drain out until you open the other end and if siphon out kinda like the same effect hope you understand

[@Sht855]

After replacing my 2010 LS air suspension with Arnotts Air Suspension and you will loose the sport, and comfort selection, I decided its time to move on with my LS and trade it for a new Camry SE. Great cars but the older they get the more expensive they get.

[@relg6982]

That’s with anything that’s worth having sir😎

[@Mabeylater293]

What actually failed in the suspension? And how many miles?

[@canoeshoe]

44510-50070 is a superseded part. It'll fail again eventually. The right part should be 44050-50170. Did you clean off the brake fluid? It'll eat through that chassis paint in no time.

Still working fine yes cleaned the area with degreaser and soap and water
