ABS and "!" lights are ON again! - Page 13 - Toyota Yaris Forums

Luxley · 04-22-2010, 12:53 PM

Thanks for the Fix folks!! Warning Lights were on all last winter. When I called the local dealer they played dumb with dollar signs in their eyes!! I can't image all the sensors that have been changed at the expense of owners all because of a poorly designed connection. I am going to try to silicone the entire connector before next winter. Mabye this will keep the slush out?! Would be nice if Toyota pulled up their socks on this obvious weak link in the Yaris Braking System.

It disappeared.
Must be the good weather.
I'll make sure not to panic when it reappears in the winter and will just take out the fuse for the abs.

I guess they'll never come clean on this problem because there is money to be made for replacing of their defective parts.

Theisbj · 05-17-2010, 01:05 PM

I just got the same problem. Both the VSC and ABS lights are on.

My Toyota Yaris is from february 2007 and they say it will cost me 9300 DKR or 1550$.

Thai_Dang · 09-15-2010, 02:42 AM

My ABS lights just came on this morning! WTF its only 3 months old. I had to manually shift it out of park by popping off the tab and pushing the white thing. Toyota what a fail.

Bumping this thread because it's almost winter again, and people may want to check their sensors when they change over to winter tires.

I'm thinking of switching my tires in the next three weeks, and was planning on cleaning the speed sensors (thanks to fidgell for the picture in post 232!) while I've got things apart. My warranty is up and I'm not paying $800 for a garage to do this for me.

So, for those that have successfully done the fix, I clean the dirt out of the sensor connectors with WD40 and compressed air, then top it off with a little dielectric grease before snapping it back together?

I wish I would've back in November... We had our first couple of days of snow and salt on the roads, and the brake and ABS warning lights showed up on the dash. I cleaned the connections and lubed them with some dielectric grease this afternoon. Hopefully it works

Dave · 12-13-2010, 09:21 PM

I wish I would've taken my own advice too

I didn't do it when I changed my tires and now the lights are on. Do I actually have to take the tires off to get to the sensors, or can this be done with the tires still on? I'll have a chance to look at it this weekend, and I'll try to make due without the ABS in the meantime.

craigq · 12-14-2010, 05:07 AM

I think it's easier to just remove the tires. From what I could see the orange rubber seal on the sensor wiring plug-end (the cheaper $50 part) displaces a bit too much when the sensor wiring plug is inserted into the sensor receptacle on the hub (the expensive part). This is probably allowing the salty water mixture in and the electrical connection goes wonky.

Guys... here a new dissatisfied Toyota 2007 Yaris customer, had the ABS and Emergency Brake lights ON since yesterday, my warranty expired six months ago, has anyone heard of a change in Toyota's response to this type of problems? (Posted Dec 15th 2010)

CB900F2 · 12-16-2010, 08:24 PM

Add me to the list of defective rear ABS speed sensors...

So far, they claim just the right-rear is defective, and they ordred the harness and hub. and they are back order.

I am fighting for them to replace the left side also under warranty as I do not want to get bitten in the a** with a repair bill if the left side goes bad for a know design fault..

yaris2010RS · 12-17-2010, 01:16 AM

sorry but there are 14 pages so forgive me, but how can we "preserve" the life of our sensors?

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

Toyota has 'recognized', and 'fixed' the issue with 2009+ model years. You should not be a victim of this premature failure.

R35c470r · 12-22-2010, 12:25 PM

hi
i had the same problem, abs signal was turned on - abs didn't work. Mechanic said the right back sensor is not ok but abs signal disappear and again turned on after two day.
tell me something. if abs signal turn on than abs doesn't work, what about VSC.

Dave · 12-27-2010, 04:38 PM

Does anyone have any specific pointers on how to get the sensor apart from the hub for cleaning?

I got the outer housing off, like asiliat said in post 170, but is that all there is to it? I just saw the two wires going into another plastic plug which goes into the hub. Nothing there looked particularly dirty. Should've taken some pictures when I had it apart.

I'm assuming that the actual plug has to disconnect from the hub and be protected with grease (but maybe I'm wrong).

The picture in post 225 looks like the whole plug comes off.

I could use some guidance from someone who's done the fix, please.

craigq · 12-30-2010, 04:56 PM

Dave, it sounds like you only removed the connector cover. You have to pry carefully from the bottom to get the connector itself off, that's the piece with the two wires. Pry from the bottom portion of the connector with a really thin slot screwdriver as shown in the picture in post 225. This is also covered in the "axle.pdf" file of the FSM found on this site. The connector holes are very small, it doesn't take much to clean the area and lubricate with the dielectric grease...

4. DISCONNECT SKID CONTROL SENSOR WIRE (w/
ABS)
(a) Using a screwdriver, remove the claw of the
connector lock portion and disconnect the skid
control sensor wire connector.
NOTICE:
Do not remove the connector cover from the
connector because the skid control sensor wire
may be damaged.

DJCrazyChris · 01-05-2011, 01:15 PM

Another winter another trip to the dealership....less than a month on our extended care warranty. Replaced the one last year free of charge (took 5 weeks to wait for the part). Hopefully not as long this year.

Dave · 01-05-2011, 10:48 PM

Awesome work and great post.

Even if Toyota won't issue a proper recall (like I think they should) it would be nice if they could at least stick with the $50 fix instead of charging their customers upwards of $700 to replace their own faulty materials.

bigdaddyhame · 01-06-2011, 02:49 PM

Hello... my wife's 2007 Yaris Sedan >80k kms has just started showing the abs/! light issue as well. Add us to any and all complaint and or recall encouragement lists... I've printed off some of the materials here to take to our mechanic just in case but for the time being we don't mind the lack of ABS. While it sucks that we are clearly not alone in this at least we can share information and help eachother even if Toyota won't stand behind their defective system and issue a recall.
