Brake warning lights !+ABS

[DandiDani]

thanx hilton. i knew that i was NOT crazy. lol.

I just had my ABS and Brake lights come on for the first time. It is snowy and brutally cold here.

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?

very interested in the pic. Stupid dealership wants to replace both sides for $1200 per side! WTF. Car drives fine...no ABS and the damn lights are on...but thats it. Can you send me that pic?

After receiving a $900.00 quote from the local Toyota dealer to replace the two skid control sensors on my girlfriend's 2007 Yaris, spurred by the dreaded stuck ABS and Brake warning lights, I decided to give Fidgell's resolution a shot. I cleaned the terminals on the sensors with some sensor safe brake cleaner and then cleaned the tiny male terminals in the sensors themselves with a tiny piece of emery board. I topped everything off with some dielectric grease and sprayed the outside of the terminals with Gunk's connector sealer. The ABS/brake lights went off after driving about 5 yards (not sitting on the jack stands, however.) I cannot believe we saved $900, which the dealer would have happily pocketed, with about 40 minutes work and a $10 trip to the auto parts store. Drove the car about 50 miles since. No return lights. Thanks for your post fidgell! I know you posted it a while ago, but I am sure you have helped countless folks since.

I have a 2007 Yaris which I purchased from my mother-in-law in December 2009 with only 3500 KM on it. Not long after I had the same problem as many here. Brake lights on and disabled ABS when driving in salt & slush. I was able to obtain the code pointing to a rear speed sensor. This past summer I purchased some dielectric grease at CDN Tire, removed the connectors at the rear wheels, filled the stationary end full of the grease and plugged them back in. Since I have done that I have yet to see the problem appear again.

I am having this same issue- ABS and Parking Brake Lights both on- it comes and goes.

My question is: Do the fault codes get stored after the ABS and PBL go out? Can you only get the fault codes when the lights are on?

Hi all,

I've got the dreaded ABS light and Brake light illuminated together...
I've managed to remove the outer cover for the sensor plug but i can't get the actual plug off. Does anyone know how this connector comes off?

Use brake cleaner on the outside of the sensor and electrical contact cleaner on the inside portion where it connects. Hopefully that fixes your problem.

OK! We need to be stirring the pot with this. I have been in contact with my steal-ership and theyre now offering up 300bucks towards the fix, and Toyota Canada is willing to chip in a bit too...HOWEVER, since I will be bringing my car to my local mechanic, as he was willing to attempt the cleaning fixes that are recommanded throughout this site (which WORKED for my left rear sensor, but my right rear sensor is still f'd), Toyota is not willing to chip in towards the parts or service as its not being performed by their overpriced inexperienced mechanics. So, we need to push Toyota Canada to do a campaign to have all Yaris's brought in and either have the connectors on the ABS harness cleaned/replaced, and/or have the company engineers design a better cover to protect these VERY sensitive circuits from our harsh Canadian climates to prevent them from corroiding.

Come on Toyota....fix this problem before we make it become a safety recall. You admit it yourselves on your website that ABS is better...and we did pay extra for it.

I know your pain. I to have a 2007 sedan with ABS. After 71000 miles it started acting up this winter with the brake like and ABS lite bouncing in and out. With the postings on this board I was able to determine living here in New Hampshire that I was experencing the same issue as our Canadian counterparts with the rear wheel speed sensors and wiring harness' and corrosion. I called my dealer and had them order the parts for both sides to fix the issue. There is a huge back order on these parts and it took them almost 3 months to get them. I had purchased the extended warranty on my Yaris and after explaining the issue to the dealer he aggreed to eat the 100 deductable and fix my car with no expense to me.

No problems since and hopefully non will show up again.

Yes Toyota should issue a recall. They issued a TSB in June of 2008 about replacing these parts in northern climate regions but only if the customer complained. Hence they knew of the problem and should correct it at no charge regardless of mileage and time owned.

Good luck.

Anyone who says that this connector is not faulty needs to take a look at it. There is clearly no rubber seal or boot to cover. This whole thing is an engineering over sight. Fixed mine today with vasoline cost $0. looking for some boots to cover these in the future if anyone finds some thing please post it.
