ABS unavailable Mercedes
Remember, even though you're getting the abs currently unavailable Mercedes light, the repair steps we show you here on this Mercedes (W204) C250, will still apply if you have an abs unavailable ford or if your abs check engine light stays on with other brands of cars like Toyota, Ford, Honda, etc. Once your abs check engine light turns on and stays on, you need to get an OBDII reader scan tool to plug into your OBDII connector under your driver's side dashboard and read out the check engine light codes. The scanner talks to your car's computer ECU and reads out the check engine fault codes that set off the check engine light to begin with.
C0034 engine code
Once you read out the code the abs light fix is as simple as determining what the engine fault code is telling us. In this video the C0034 engine code simply means that the front right ABS wheel speed sensor is out. This is a sensor that plugs onto the inside hub of the wheel, supplying wheel speed to the car's computer. When this ABS brakes sensor fails, the system cannot figure out how to best apply the ABS brakes, so it turns on the abs check engine light, and gives up, saying that ABS is unavailable. Now you have to fix the error message and clear that C0034 code root cause for good.

You can also get the condition where your ABS light stays on Toyota Camry models, and you can get abs light stays on Honda accord vehicles as well.

Another safety tip my Dad taught me is that especially if you are using a factory jack or hydraulic or any other jack for that matter, and don't happen to have a proper jack stand, that after one takes the wheel off the car, to put it under the car on the side that you are lifting, so that It acts as a safely stopgap and even if the car falls, it will not fall far, and also if one is caught under part of the car if this happens, it will not cause a bad day/week/month/year/life/death..

Does the Genuine Mercedes-Benz RPM Sensor 204-905-29-05 work on the both front left and right side? Thank you!

[@abdulamiraalubaid3056]

hi, can i ask you what type of diagnosis device do you use please?

[@qcere]

Hello sir, i have a question regarding this. My mercedes c250 brakes when i gas it, and i have this same ABS alert.

[@carbuying]

Not sure how that is even possible since takes putting your foot on the brake pedal to initiate the brakes so for something that severe I would recommend you bring it to the dealer

[@jd5125]

Sir, how much did the new wheel speed sensor cost? Thanks

[@carbuying]

about $70 ✅ Genuine Mercedes-Benz RPM Sensor 204-905-29-05 amzn.to/2xZI2IL

I have a 2007 Camry and these lights are coming on occasionally and sometimes it feels like the car wants to quit. I just had the alternator replaced after it quit on the highway. Any suggestions? I’m trying to make it last the month before I take it in due to extreme financial difficulty.

The wheel speed sensors are likely wearing down

Use a long extension and go from the top and it takes about 10 seconds...

@@laboratorio-tomatesdelguad5585 the quickest way to fix a problem... is to trade it in like most German car owners do. A CLA250 is not worth the cost of its maintenance at dealership. Find an independent shop is your best option 👍

Mine won't shift outta park but doing the same thing with the speed sensor codes

[@enterthelegions]

Hello. I have a weird issue with the ABS system on my w204. The code coming is from front left wheel sensor. I have replaced and swapped the sensor and changed it to the right side as a test. Sensor and wheel bearing are both ok and tested but the error still remains. There is no other error. Just the front wheel speed sensor on the left. What could it be??? Is the ABS control module fried ?? The car has only 49k km on it.

[@illia.s]

Did you figure it out? Having this issue right now.

[@enterthelegions]

@@illia.s Yes i figured it out myself. It was both ABS sensors. I replaced them both and everything was fine. The voltage was showing OK on both sensors and that was mis-leading. Thats why i assumed that the sensors were ok but actually there were not. ABS sensors are the most common issue in this series. I really hope you work it out. Good luck!

[@aliyuadamu3945]

So i have this exam code on my car, i changed the abs sensor. Went for a drive and the abs light came back. I run the diagnostic and no fault codes again but abs light is still there. Any suggestions please

[@carbuying]

We have heard people say it took a day for it to go away.Another thing you can try also is turning your steering wheel all the way over to the left and until it stops and then all the way back until the right until it stops, do that a couple of times, that sometimes helps resets the sensor. If that doesn't work then it could be that it set a fault code in your engine that you're OBD2 scanner is not seeing. Many of the less expensive scanners can't get deep enough into the Mercedes computers to see the fault, and reset the faults and check engine lights. So for example until we bought the BlueDriver OBD2 reader which is about $100, we couldn't see certain faults but then once we got this unit and plugged it in we were able to see the faults and clear them as well. But this ABS particular code should disappear on its own. If it doesn't you might want to check the other side wheel speed sensor as well, read the code out of the engine and make sure it's still referring to the same wheel sometimes it's best to replace these in pairs both the left and the right side. Let us know what you find.

[@GreyWolf_444]

I had the same issue and the abs is still showing fault but its not in my obd reader anymore .

[@AnthonyJohnson-mx3kp]

guys, do not raise your car with the mercedes emergency jack found in the trunk in order to work on your car. these jacks can fail when used on not level ground qnd they are cjeap piecea of crap. use a good quality hydraulic jack, find a spot for a jack stand and also put something like the wheel that you removed, underñeath that side of the car. if you are not experienced at this then get a second opinion before working on something like this. he says dont put your hand under there but that isnt the only issue. you are bending down going under and reaching under the vehicle and it can fall and kill you

[@korionterivers9995]

Why are all the obd2 u listed over 100 dollars. Are their any cheaper reliable ones??

[@purehitman24]

I don't recommend using PVC. If it snaps and you fall on it you're in for a bad day.

[@robertkennedy1737]

I can't believe you don't put a jack stand under the car, or at least a cement block with some wood between it and the frame. If that car comes down, even if your hand is not under the rotor, you are going to have a bad day.

[@Thomthethird]

Just drove a long distance and discovered the lights went off and didn't come on again I guess driving these cars on really bad roads sometimes can trigger the lights to come on

[@siyabongakhumalo6319]
