ABS and "!" lights are ON again!

========= I solved my abs / brake light problem =================

I had this problem and the dealer proposed to change the hub assembly and wire harness. There was no way i would pay 700$ for ABS to work properly.
Since everyone here was saying it was a corrosion problem with the connector in the hub assembly, i gave it a try and repaired it myself.

I opened the connectors, used WD-40 to wash the terminals inside the connectors, cleaned the connector of the WD-40 with some airpressure and then filled the connectors with dielectric grease (even tho regular grease protects from corrosion, the grease itself conducts electricity and could cause some weird shorts between the two terminals, dielectric grease prevents this).

I did the repair january from last year and its been working fine since then. I think i will reopen the connectors and redo the same job before it gets cold just to be sure everything will continue to be fine.

If your harness / sensor connector is in really bad shape, this repair might not work but for the price its worth the try. (took me between an hour or two and cost only the 6$ dielectric grease tube and some wd-40). Also, i used wd-40 but I guess connector cleaner would make a better job.

I am definitely going to have to try this when the weather gets warmer out.

Unfortunately for me, my brand new speed sensor is broken again. It seems to be just ice build-up around the sensor though, so only time will tell if it's bit the dust. It happened after one day was plus 0, then the next it went down to almost -30. It's still pretty cold out (-14), and the ABS and ! are still lit.

Maybe I will try a hair dryer to the sensor to get rid of the ice.

You are OK to drive. Brakes will basically be functioning same as none ABS equipped vehicles.

Yeah, I've been driving with those lights on for about 8 months now... it's fine, just no ABS. Waiting till spring to try to clean the contacts.

I just got the !emerg lite and ABS on today. 2008 Yaris with 30,000km, dealerserviced from day 1. Un-freaking believeable. I actually thought this thing would run like a top for the first 10 years.

Since the repair will cost about 10% of the cars value, and the only thing I'm losing is the ABS function, it makes zero sense to repair this.
Have to say, looking at this thread and the fact that there is no recall/repair for a fix, this will be my last Toyota. I've had 2 camrys (93/96) and a Sienna, but if this is an indication of their commitment to quality, I'm no longer interested in the product.

As they say, it takes years to build trust and a moment to lose it. (yeah I'm pissed )

Just had this issue. Warranty lapsed. I am not a mechanic, does anyone have pictures where these contacts/connectors are so I can clean them?

I can take some pics but it won't be until summer ... since I don't have a garage where I can work in the winter.

But if you need to do it now you can always take a look here http://www.etimago.com/yaris/repairm...%20Control.pdf

Page 97 is where the installation/removal diagrams are for the ABS sensors are on the front and rear wheels.
