When we take cars for AirCare (emissions testing) here in BC, there's a
note right on the inspection form that ABS-equipped cars may display an
error code for a short time after testing, for exactly this reason.
Happens with our minvan ('96 Plymouth Grand Voyager).  The light does go
out after a little bit of driving, and all seems to be normal.

------------------

The computer said "what the heck is going on here" and set an ABS code
because the rear wheels weren't even trying to rotate.

yes it is a Honda civic EK3, 98 model. but front wheel drive.
the repair was just transmission oil replacement.
any idea for the reason of this behavior?

Without taking the time to wait until Psychic Wednesday, it sounds like
your (HONDA)? is an AWD version, like a CR-V or a Pilot, or an ELEMENT
and the dealer was performing service on the rear differential, maybe
like this:

Just be sure to TEST your ABS on some snow or gravel to be sure the
pedal makes the usual vibration when you do a sudden stop that causes
the wheels to slip. The light may come on at that time too.

Next time, it's a good idea to quote your model, year, and mileage.
Location is helpful too, since safety features and specs vary from
country to country.

the ABS indicator light stayed ON for few miles after i serviced the
car. during the service it was help up and front wheels were powered
by the engine while rear wheels were held stationary. could this be
the reason?
