ABS Warning Light - Super Easy Fix!

Very informative and clear. Thank you for sharing! Good luck!

Many thanks - you are very welcome, and thanks to you for watching!

Now I know where to start with my ABS warning. My mechanic s few years ago said I might just want to let it go because it was probably the module which costs massive bucks. Now that I'm doing my own repairs, this is something I'll definitely check out. Someone said that you can pick up an abs module from the junk yard for not much, so maybe do that if I have to. Once you start working on your own car it actually becomes fun!

[@bigtalltim]

It really does! - as soon as you get over the thought that it must be really hard, it is basically just big boy Meccano! Aftermarket sensors are fairly cheap by the way - problem with breaker yard ones is that you don’t know what condition they are in… for a few quid more than the breaker would charge you get a perfect one with a warranty! Definitely give the fix a go though!

Most ABS problems are either the sensor or the sensor ring. I recently had the ABS light on my own 2003 XC90 come on and the error codes pointed towards the front right sensor. I changed the sensor ring (just shy of a tenner from GSF) and got sidetracked by a small tear in the outer CV boot which was leaking grease. The new ring didn't fix the problem but it was still worth doing and finding the torn CV boot was a blessing in disguise. I fiited a new sensor (£36 from a local motor factor) and the problem was fixed. This has been documented on my own channel.

brilliant, thanks. going to do this tonight but the offside!

[@bigtalltim]

Should be the exact same process - good luck!

Great video for the front sensors. I just did the rear off side and it was a pain in the backside as the middle row of seats needed to be removed and carpet lifted to get to the connector.

[@bigtalltim]

Cheers - and yes… a much more involved job at the back… for those who aren’t familiar, you have to remove the 2nd row of seats, pull the carpet back, pull out a block of foam, pull out the air con ducting, and there is a round flap with the abs connector and the fuel pump actually - same access point for both

@@bigtalltim Are you in the Volvo xc90 UK owners club on Facebook? Lots of info there and perhaps share your video there.

[@bigtalltim]

I’m not now, but did used to be… I haven’t used Facebook for a few years now

[@floydraser4603]

Very well explained and easy to watch, thank you.

[@bigtalltim]

Glad it was helpful! Thanks for watching!

My ABS light goes off after turning the car on but then comes back on after a while, Also have the Anti Skid warning sign on. If i replace the ABS sensor will it also fix the Anti Skid warning sign aswell? Great video..

[@bigtalltim]

It’s a fair bet that it would, but to avoid loading the parts cannon unnecessarily, stick a diagnostic computer on it to read the code… the abs light will sometimes only come on above 20kph so it could be an intermittent reading when travelling, but could also be as simple as a dodgy connection - make sure you check the sensor connection is good… condensation in winter can be an issue, so rule that out and maybe use some contact cleaner! Failing that, check the tone rings don’t have any rust or debris in between the castellations - that can be enough to provide a dodgy reading which isn’t quite bad enough to register a DTC, but is enough to light up the warning light for that journey. My guess would be tone ring issues rather than sensor - sensor failure is a straight DTC and permanent light… let us know how it goes!

[@neilmonaghan5100]

@@bigtalltim Thanks for the reply. The code I'm getting it ABS-0109 ( Communication between control modules. Communication with the Steering Angle sensor. Internal fault) & ABS-0022 ( Right front wheel sensor. Faulty Signal) Any understanding? Thanks alot

[@bigtalltim]

Ok… first part, sounds like the steering angle sensor that is part of the clockspring has failed… fcp euro did a great video on replacing the steering angle sensor. On the abs sensor, it could be that some flakes of rust or metal chips have stuck to the end of the sensor and are affecting the signal… surprising how easily the signal can be disrupted… worth taking it out to have a look… check the ring too - metal particles in mud or rust between the castellations on the ring would cause the same. The intermittent nature makes me suspect the sensor is working, but is being confused by magnetic debris

[@neilmonaghan5100]

Thanks alot for your help. If I was to take it to a garage how much do you think it would/should cost?

[@bigtalltim]

A good few hundred quid - definitely worth having a look around first in case it is something straight forward! Definitely start with looking for contaminants on the tone ring/sensor

[@garyhaley8161]

Great Video!!! I need to do the rear ABS sensors. So, if anyone has a tip or a video that would be great.

[@bigtalltim]

I believe that the sensor clip can be accessed in the xc90 in the same way as the v70 - check this out: kzbin.info/www/bejne/rqvchamQibpslbssi=3paJENEZHVUOXtT8 You definitely do not need to drop the fuel tank!

[@queeny4624]

Hi can i ask what machine you used pleased. Volvo xc90 with the same abs fault - showing 0700 - been told needs a new ABS pump/module rebuilt. But looking on a lot of videos and pages - it can mean a number of things, but on volvo (garage is a 2 hour drive away) can see what the actual problem is

[@bigtalltim]

Hi! I have a couple of different diagnostic computers, but the main one (and the one used for this) is an icarsoft cr-max.
