ABS and "!" lights are ON again!

[invisibleghosts]

First off let me thank everyone for posting such good information on checking, preventing and replacing in all of the above posts!

I've followed the instructions and have removed both sensors, the first was dirty, but intact, the second....not so lucky.

So I managed to switch out the old, broken, wiring and sensor (I'll call the male end) but I'm a bit lost on the other side (female) end. I had a few pins that were broken off (tons of sand/salt/snow in Winnipeg) and I'm not sure what part or process to use to replace the "female" side? I wasn't able to find anything mentioned in the previous posts on a DIY...any advice?

I've been taking photos as I've gone along and I hope to post them all once I've completely finished to help others. I'll admit I'm not very handy, but I'd rather not pay the dealership for a job that I can do myself!

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.

Can anyone tell me where I would access the Canadian version of the TSB? My ! and ABS light just came on last night driving home in a snowstorm. I'd like to just replace the necessary parts rather than the whole assembly if I can, the dealership of course quoted me for the hub & sensor wiring.

Can I get instruct them to replace just the sensor wiring? How will I know that it is just the wiring and the hub is not required? I'm no techie with cars so I wouldn't know if thats a reasonable request.

I have a 2007 Yaris with 170,000 km on it.

Any advice would be appreciated, keeping in mind that I am not knowleadgeable about cars.

Regards and thanks,

Chris.

I haven't seen a source for Canadian TSBs, but if you look at the "Brake Control" section of the service manual (which is posted at the top of the DIY section), page 102 shows what's involved in replacing the senor/wire.

The wire is cheap (~$30), the sensor is a bit more (~$150), and the hub is ~$350. I would imagine that you'd have to add 2-4 hours of labor to that.

They probably just replace the whole mess, rather than taking the extra time to diagnose each portion of it.

Thanks CTScott, appreciate it.

see my post #251 on page 14 for details on the canadian TSB

The TSB (CDN version) the number is:
TSB3027 (issued July 3, 2008 revised on March 19, 2010) - Canadian TSB Version
DTC (diagnostic trouble codes)
C0210 - Rear Speed Sensor RH circuit
C0215 - Rear Speed Sensor LH Circuit

I have a printout of this TSB and can scan it. Can we post pics here?

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. Filling out a transport canada complaint this evening.

[da1nonly]

Filled out a transport canada safety complaint today as well...

hopefully this gets addressed...

[supahsain]

Another unhappy customer. Just filed a safety complaint but I highly doubt it will do anything.

[Andymeo]

Unfortunately my car has the same problem come out today, both the ABS light and brake light ON. Don't know what I can do. Warrenty expired a year ago and I still need to keep the lease for another year. Too bad.

[supahsain]

Wow, I guess this is affecting more people than I thought.
Everyone should create a complaint

Just file a complaint at Transport Canada.

Hi Guys~
I have 2007 Sedan model also...the other day both parking brake and ABS lights came on then both went off inself after driving it about 30mins. A few days later those two lights came on again then went off itself...after reading up on these posts i went to check under the car (both rear speed sensor wires and connectors). After observing i did not see any chafed or broken wires and damage to connectors. After cleaning the connectors and sensor areas with contact cleaners and re-connected them back.
I was fortunate to see no damage to wires or connectors. So far i don't see any problems with parking brake and ABS light. I think it's fixed for now~

P.S. I did check with OBD II but like the others peoples there was no fault code shown.(at least my case)
I do not know why it did not record any fault code in computer??

A standard OBDII reader can't read fault codes from the ABS ECU. You need a Toyota TechStream Tool or an enhanced diagnostic tool to read fault codes from any ECU other than the ECM.

Oh I C~~ thanks for the info CTScott.

FYI guys mine had 73,000Km right now

By the way, you can actually read the DTCs using just a jumper wire:

With the ignition off, jump the CG and TC pins on the OBD connector:



Turn the ignition on and watch the ABS light. If there are stored DTCs, It will flash in a pattern to indicate the code (71 for example will be shown as 7 quick flashes, a short pause, and then one quick flash).


C1271/71 Low output signal of front speed sensor RH

Thanks to CTScott, checked my OBD connector and jumped those two pins
confirmed that i have 73.

But there was also other lights were also blinked like transmission, airbag, P/S. etc
what are these CTScott??

Well, started my car (2007 Yaris Sedan) @ 6:30ish AM to warm it up and noticed the (ABS) and "Brake" light were lit. Tested my E-brake momentarily - no change. After thumbing through the manual and seeing that having both the ABS light and Brake light lit were signs to not drive & call the dealer, I sat and cursed for a few moments. Briefly tested the brakes in the driveway. Seemed to work fine. After both wondering if I should risk the drive to my morning class and consulting with a relative - I risked it & drove. Gingerly made my way through the snowy/salty slop to school. Then after class made it the (thankfully) short distance from school to the dealer (the very same dealer I had bought the car from). After driving the car into the svc. bay, I was greeted by being told a $120 would be applied as a diagnostic charge. After staring wide eyed at the service guy and expressing my disbelief, I reluctantly agreed - after all I was trying to do the right thing. Right?

To make a long story short... It was the right-rear wheel speed sensor harness. I was told there was 1 available locally and it would take awhile to get my car worked on. Told them to get it done.
After writing a note to my former sales guy expressing my concern over the $120 charge and leaving for a bit, I returned to the dealer. Talked w/ my sales guy only to find out that this fix wasn't under warranty (since it wasn't powetrain/tranny related). He tried talking w/ the service manager, vouching for me and tried getting the service charge eliminated. No dice. He sincerely apologized to me and I paid up and left. Disappointed. $220.35 total out of my pocket. Some of you may know that I bought this car Certified Used last May. My first Toyota, and first newish/modern car. Love it's driveability, reliability, and ease of use. Didn't like this situation too much though. Well, it can only get better, right? I live in a winter wonderland...

I should add: Today the car broke 50,000 Miles too. I bought it with little over 42,000 on the Odometer.
