ABS and "!" lights are ON again!

[Kasbien]

2007 Toyota Yaris Sedan with 96,000km.

ABS and E-brake lights came on while visiting the interior of BC where the temperature ranged far into the negatives. Found this thread and performed the DIY fix of contact cleaner + a light coating of dialectic grease. No lights since, and I've been back into some temperatures hovering around freezing in my area and a few highway trips. Thank you contributors for pioneering a solution! I'll likely do this once a year for preventive maintenance.

PS: A spray bottle of water to clean things off before starting is very helpful if your undercarriage is covered in "winter grime." Then use a hair dryer or heat gun after cleaning out the contacts with cleaner to help it evaporate faster (if you're working in cold temperatures like I was).

I have a 2011 5 door yaris. The parking brake, traction control and ABS lights had been occasionally coming on at the same time. Now they have stayed on permanently. I disconnected the cables going from behind the rear seat to the hub on each of the wheels and measured continuity of the cables. Both cables were fine. I tried clean the connectors of the ABS sensor with contact cleaner and nothing changed. Any other tests I could try before randomly ordering parts? :) Thanks for any advice.

Here is an update... I got two new rear bearing hubs with abs sensor in Ottawa for $115 after taxes for the pair. I replaced the rear right, it seemed to fix the problem, but after about 5km drive the lights came back on. I replaced the left one and have not had an issue since. 7 of the bolts holding the hubs on came off easily, one needed a bit of heat from a propane torch. The new hubs did not come with replacement bolts. The hubs are tricky to remove because of the rust. I watched a YouTube video by Alan Howatt "Toyota Yaris Rear Wheel Bearing Removal...No Problem" and it came off easy following his directions.

Hello @ps667stop. Where in Ottawa did you manage to find rear bearing hubs with abs for that price? I am from around here too and am dealing with the ABS and (!) light on my dashboard. When I checked the connector attached to the hearing hub, it was squeaky clean. I still tried squirting some electric parts cleaner, but it did not seem to help in any way. Looks like I may have to change the bearing after all. Its a shame because the bearing seems to work just fine. I look forward to hearing from you. Thank you for your time. Cheers!

A place called "AutoShack" were selling them out of Ottawa on ebay canada for $98.87 for a pair, plus taxes, free shipping. They have an actual store address at AutoShack 201 Iber Road, Ottawa, Ontario K2S 1E7, Phone (613) 287-3880.

Its written "made in China" on the box, but they looked exactly like the originals. My wheels have not fallen off yet
Hope this helps.
