A couple of times now we've seen the 'ABS' light come on in our '97
Avalon, accompanied by a flashing 'trac off' light - it did it once
yesterday, then once again today.
Both times, the car has continued to operate normally without any obvious
braking/handling problems - until the engine is switched off and
restarted. At that point, the ABS and trac lights clear, but the clock on
the dash resets and the engine struggles to hold idle (although the car's
perfectly driveable). After a subsequent restart, everything's fine - no
warning lights, no idle problems.
It's icy and snowy up here right now, but it wasn't exceptionally cold on
the two times this has happened (i.e. the car's been fine when it's been
much colder). A few miles prior to this happening the first time though I
did clear snow and ice build-up from the passenger-side front and rear
wheel-wells; I wonder if I dislodged a sensor wire such that it's now
making intermittent contact? (OTOH, the car's got just short of 200k
miles on the clock, so it's probably long overdue a few failures :-)
Oh, both times the lights have only appeared when pulling away and making
right-hand turns - that's probably simple coincidence, but I figured I'd
I'll dig around behind the wheels later and take a look for any obvious
damage (should have done that before posting, I know!) but are there any
other obvious things I should be checking? Is the frequency of the trac
light flashing significant? What about the time reset and rough idle?
That just seems odd, like a computer glitch rather than braking system
