ABS warning light assistance
Discussion
We have an '06 Yaris that has an ABS warning light (and a brake light) on and aren't in a position to get to a garage with ease.
The car has recently done about 500 miles in one stretch in the freezing temperatures and until it was left alone (in temps down to -21), the ABS warning light hasn't been seen before.
Could this have anything to do with the cold and is there anything we can do to to 'reset' the ABS system? The car's only done 15,000 and was serviced 4 months ago.
Thanks

Were you wheel spinning a lot? I had my ABS light come on last winter after a very slow drive up a hill with lots of wheel spin. It was apparently due to the system being confused by the difference in speed between the front and back wheels for a reasonable period of time. After driving on cleared roads for a mile or two it sorted itself out.
Otherwise it could be slush/dirt on one of the sensors?

It will almost certainly be a wheel sensor that has failed or is gunked up with nasty winter road grime. Normally the system will reset itself when it next self tests (i.e. when the car is next started) - if the light stays on it will need attention but is ok to drive, albeit in the knowledge that the ABS isn't working.
Thanks all.
No, this isn't after a particular wheel spinning (although it has happened recently in the ice/snow) and the car has been restarted a number of times since the light's been on.
It has been through a very tough time recently, so hopefully it could be the sensors. As for cleaning them, is this something that I can get to and do?

Have you checked the fuse for the ABS module? If it has gone, replace it. If the fuse goes straight away then you have a fault either on the module or power supply wiring to the module.
Are all electrical connectors secure on the ABS module?
Are all the sensors in place? They rely on induction and if they have migrated then the module will recieve erroneous readings. Can you see any damage on the connections/wiring?
Also I think it has been mentioned, is there a buildup of gunk on them?

Oh joy!The thing's had 8 recalls already.

4 years old and 17,000 miles... it doesn't go along with the "legendary reliability" they like to portray.
That's the understatement of the year. Absolutely piss poor IMHO - there is no way that wiring looms should only last that long, no way. My 5-series got to 120,000 miles before it needed an ABS sensor, and even my MG made it to 85,000. It seems a bit too coincidental to me that both rear sensors and wiring should be faulty. I've come across ABS faults before on a Japanese car (I imagine closely related to the Yaris), where the rear sensors have reported faults with the cause being water ingress into a junction block in the nearside front footwell, a clean up and drying out of the wiring later, no more problems.
