ABS and "!" lights are ON again! - Page 10 - Toyota Yaris Forums

grchristoff · 01-07-2010, 02:28 PM

Hi there, new to the list but I am having the same problerm; ABS/Brake light came on just recently during a snow storm.

If someone has pictures of what needs to be changed that would be great as my 2007 yaris 4dsd is off warranty now.

I wouldn't think it would be too hard to install the sensor or wiring but resetting the computer is probably something the dealer would have to do.

From what I can tell the lights should go off by themselves once the ECU regains connection to the speed sensors. I know this since it happens to me once the ice/snow/sludge/whatever is dislodged from the sensors, my lights go back off and ABS works again.

For those of you looking for part #s, I have them for the 2007 Hatch, dunno if they are the same across all years:

SENSOR, SPEED, FRONT RH
89542-52050

SENSOR, SPEED, FRONT LH
89543-52050

SENSOR, SPEED, REAR RH
89544-52040

SENSOR, SPEED, REAR LH
89544-52040

The wire harness is:

WIRE, SKID CONTROL SENSOR
89516-52090 NCP91..CND; RH
89516-52100 NCP91..CND; LH

You can go to the DIY section and download the 2007 Yaris Factory Repair Manual. or go on line to http://www.etimago.com/yaris/repairmanual/.
From there go to brake control or BC
for the front it BC 94 - 97
for the rear it BC 98

When i did it i was able to park inside a heated garage. Wash under the car to remove the road salt and that stupid anti-gel crap they spray on the roads here. That stuff is so bad for cars. It the same stuff they use on planes and if left on for a while can cause problems. Anyways once that is all clean. Disconnect the negative terminal, and start in front. I used contact cleaner it doesn't leave any residue and film. Clean the sensor and the chamber it goes into. Not sure if dw40 would be good for the chamber since i believe it need the fiction to tell the abs brake sensor whats going on. Do the same for the rear plug and apply dielectric grease on the connections. Iy should be good till the summer.

After doing this i found that it still comes back every once in a while, But when it very cold and the car sits outside for more that five hours. I thing it because the grease freeze and can't work as well. But after five to ten minutes the light goes out. or when i restart the car its fine for the rest of the day. I'm hoping it just a problem with the early models. If so maybe i can get parts from a 2009 or 2010 and switch them out, if there the same. Hope this helps.

I had these two lights come on last week, and ABS didnt work during that period. Yesterday I jacked the car up, took off the rear wheels and fixed it myself - I have only a basic knowledge of fixing stuff, the most Ive done on the Yaris to date is change front rotors/pads so no expert knowledge required!

Once the wheel is off you will see a plug - the only one you will see - on the rear of the drum near the axle. A small screwdriver is needed to push the plug (gently) off the socket and hey presto....Get cleaning! I used a compressed air cleaner like one would use on a PC keyboard to clean the snow/crap out then WD40 to clean. Cleared any excess off with the air again then put the plug back. Finally a little grease on the small gap between plug and socket and wheel back on.

I got in turned the key and drove off.... NO lights on.... ABS working as it should.

I suggest everyone do this BEFORE going to the dealer as it will save you a fortune. It took 20 mins to do both sides and is as easy as taking off the wheel!

Southern Ontario weather does cause problems to the little car, but this is a free fix... well free if you have cleaning products already in the house!

If anyone wants it, PM me and ill go outside and photograph the plug area for you... But I dont know how to post it on here so ill have to email it!!! Proof its easy to do eh?

This small step caused me hours of frustration last spring when I installed my wheel spacers! Argh!

Yep, ABS works again for me too. I used WD40 and then dielectric grease to coat the plug to keep salt out going forward. When I switch between summers/winters, I'll probably wipe and re-coat as needed.

Yes, definitely need a screwdriver. Pry the tab gently open at the top, and then push it out and away from the drum brake itself (I used the same screwdriver - flat head to push it out). Make sure to use WD40 or the like and soak it for a couple of minutes before trying to remove, minimizing risk of breaking the clip. It should make a small "pop" sound when it comes off.

BTW, I joined the forum JUST thank you for reporting this fix. :D

I would appreciate a jpeg of the plug. My email is expat26@yahoo.com. Many thanks for taking the time.

devinlamothe · 01-07-2010, 07:00 PM

Sweet you know what, I think I will try that tomorrow. Maybe I will post a DIY.

Also wouldn't hurt to apply some dielectric grease on the connection ... maybe that would help keep out some of the grunge.

I'll see if crappy tire sells some.

grchristoff · 01-12-2010, 07:43 AM

This sounds pretty easy and straight forward. I plan on doing mine this weekend.

Spockis53 · 01-13-2010, 04:40 PM

I have a 2007 Yaris with ABS. The first rear ABS sensor and wiring harness needed to be replaced (under warranty) at 59,000km. And now the other rear ABS sensor and wiring harness need to be replaced at 80,000km. ... for $900.00 !!!

It seems these things are becoming consummables!

WOA OK first of all the parts shouldn't even come close to that $, your dealer is ripping you off like CRAZY.

I would first try the DIY here to see if that fixed the issue.

mijemc · 01-15-2010, 06:31 AM

Hej
I have a Yaris from 2006. I have it from brand new 30-3-2006. I am from Denmark
At 36.243 km. ABS VSC lights came on. fix by the dealer.
At 41.277 km. ABS VSC lights came on. fix by the dealer.
At 104.000 km. ABS VSC lights came on. the dealer say that there is no longer warranty on the car. Damm !
Today I am startet to do the things that figdell is telling, hope it works.
I will see if I can take some fotos today.

I hope that you can understand my School English.

mijemc · 01-18-2010, 10:33 AM

Hej
I try the things that figdell is telling about, but no luck.
It a shame, becouse I like to drive my littel car.

Doc Zaius · 01-18-2010, 11:57 AM

That is too bad. I hope it works for me when I try it!

Me too I still haven't gotten around to do it yet. I just bought a new torque wrench so I will be doing it soon.

Man I really hope it works.

fidgell · 01-19-2010, 08:59 AM

Just an update as its been a few weeks since I did "the clean"... Its been VERY cold and wintery (as usual) here in Barrie, Ontario. The lights remain off and the abs is still working, so I hope the guys trying this have some luck and save their money!!!

As for dealers just replacing expensive parts, this should ONLY be done after an attempt at an extensive clean - they cant be bothered to try and just want the money. Im sure many people have handed over the $750 or so when it could have been done with a half hour clean.

Good Luck
