ABS and "!" lights are ON again!

[Kazimodo]

went in today , the little outer shell is easier to remove than trying to
remove everything at once with just jamming a mini screwdriver under the connector
once the outer housing is removed , it is still touchy to get the connector to
come out of the sensor , both sides looked good and the dielectric grease did not
change anything for me , both abs and " ! " lights are on , time will tell if they
continue to go ON and OFF 50 times an hour when driving ,
I've been looking at those warning lights for over 5 years , don't care ,
only thing is once a month the brake pedal goes to the carpet with no stopping
and the grinding feeling typical to ABS brakes .
Back to the drawing board .....

anyone in sauga/toronto have an 06-08 yaris with cruise. looking for someone to help me install it

Does ANYONE know how to COMPLETELY DISABLE the ABS system and clear the codes? I'm talking so the main ECU doesn't even know the car has ABS, so the fault codes don't come up??

I really don't want to fix this expensive problem and already know it is the rear right sensor causing a problem, but my vehicle won't pass inspection with it throwing codes. I already took apart the connector and cleaned it but it didn't fix the problem.

I removed the two ABS / traction fuses from under the hood and tried clearing the codes with a scanner but it doesn't work. It still knows there's an ABS module somehow. I WANT THE CAR TO THINK IT DOESN'T EVEN HAVE ABS AT ALL SO I CAN PASS INSPECTION.

Thanks

I'm joining the club. Paid $1000 for a 2007 Yaris with 300,000. I'm at 315,000 now and the infamous ABS and brake lights have come on. After reading this thread, it looks like I don't have to worry much. Bring on Toronto winter lol

I think you made a wise purchase! I hope you have a good luck with the car.

The ABS module went out on the Ford F150 I was considering buying a used car lot. I told the guy fix the ABS module And I’ll buy it. He fixed it and it cost $700. So I bought the truck. In New Jersey vehicle without working ABS will not pass inspection.

Of course it’s not necessary. And statistically it doesn’t prevent accidents or injuries or deaths to any measurable degree.

What error codes do you have? Perhaps we can figure out what is wrong with it. It might be an easy fix If you can do the work yourself

Welcome Max! These are great cars, and I am sure it will work well for you.

I have had the same lights on for 3 years now, and no problems. My biggest problem is the occasional passenger that whines about it and thinks the brake system is going to stop working during the drive. I have been watching this post for a while in hopes that someone will find the cure. But my lights are still on, and the car still drives fine.

2007 Toyota Yaris Sedan with 96,000km.

ABS and E-brake lights came on while visiting the interior of BC where the temperature ranged far into the negatives. Found this thread and performed the DIY fix of contact cleaner + a light coating of dialectic grease. No lights since, and I've been back into some temperatures hovering around freezing in my area and a few highway trips. Thank you contributors for pioneering a solution! I'll likely do this once a year for preventive maintenance.

PS: A spray bottle of water to clean things off before starting is very helpful if your undercarriage is covered in "winter grime." Then use a hair dryer or heat gun after cleaning out the contacts with cleaner to help it evaporate faster (if you're working in cold temperatures like I was).

I have a 2011 5 door yaris. The parking brake, traction control and ABS lights had been occasionally coming on at the same time. Now they have stayed on permanently. I disconnected the cables going from behind the rear seat to the hub on each of the wheels and measured continuity of the cables. Both cables were fine. I tried clean the connectors of the ABS sensor with contact cleaner and nothing changed. Any other tests I could try before randomly ordering parts? :) Thanks for any advice.

Here is an update... I got two new rear bearing hubs with abs sensor in Ottawa for $115 after taxes for the pair. I replaced the rear right, it seemed to fix the problem, but after about 5km drive the lights came back on. I replaced the left one and have not had an issue since. 7 of the bolts holding the hubs on came off easily, one needed a bit of heat from a propane torch. The new hubs did not come with replacement bolts. The hubs are tricky to remove because of the rust. I watched a YouTube video by Alan Howatt "Toyota Yaris Rear Wheel Bearing Removal...No Problem" and it came off easy following his directions.

Hello @ps667stop. Where in Ottawa did you manage to find rear bearing hubs with abs for that price? I am from around here too and am dealing with the ABS and (!) light on my dashboard. When I checked the connector attached to the hearing hub, it was squeaky clean. I still tried squirting some electric parts cleaner, but it did not seem to help in any way. Looks like I may have to change the bearing after all. Its a shame because the bearing seems to work just fine. I look forward to hearing from you. Thank you for your time. Cheers!

Great. Thank you @ps667stop. I will check them out :) cheers.

Really?? Are you sure it isnt the air conditioning? Or the Muffler?
So I leave the car, and rent a car to drive for the "two, maybe three days to fix it" answer I get from dealership...Three days later, receive a call stating the ABS is not working, and harness and wiring assembly need to be replaced- oh and by the way, the part has to come from Japan and will take 3 weeks- estimated.."We have rental cars here at the dealership" ..Well thanks Biff, I had planned on walking the 20 miles to work in February, average temp 30 degrees; but if you have rental cars... So I rent a car from them. Three weeks later, part arrives and dealership happily calls to inform me the car is "ready to Go!" And all for only $1256.00 american...Parts, labor, and rental car..So Biff mentions that there is a magical 800 number (Toyota Customer Service) that might help me defer some of the cost..Being a christian, I will only say they came short of laughing at me for calling, and actually suggested I return to the dealership, to see if "they" could help.. I did read one post, where they sent a certified letter, but it was Canadian; where they care...Any suggestions as to where to go from here?

Don't know if they have it in the states, but here in Canada, if you go to the dealer for regular maintenance, they have what's called "Good Will Warranty" for out of warranty vehicles. Dealer pays 20%, customer pays 20% and Toyota Canada Pays 60%. But if you've never been back to the dealer for any service, you'll have little to no luck getting it, because they have no reason to help a customer out that's never spent any money at their dealership.

Has this been recalled by toyota yet????????

["G"]

Lot's of good info in this thread. My abs/ brake light recently came on so I checked my rear sensors and this is what I found. One pin basically corroded off completely. Their has to be a replacement sensor available with out having to buy a whole new hub. Or an updated part. I think i'm going to try and remove the sensor and see what happens. Are their any updates on whether or not you can buy just the sensor???? From looking at the base, it looks like a twist and pull removal. Similar to a parking light bulb. If the whole hub needs to be replaced then it looks like a bad design on Aisin's part.







Here is a link to Aisin's website >> http://www.aisin.com/product/automot...ake/index.html If you scroll down you will se they are mighty proud of their offerings The speed sensor with integrated hub is the exact toyota model! The bottom speed sensor which they refer to as "stick style" is used on the front of the yaris. I think we should all email aisin and say wtf!
