Abs light went on

I was driving and my abs light started flashing. I didn't know what it was so I pulled over, turned off my ignition, and looked in the owners manual. After gaining some knowledge I started my vehicle and the light was gone. Should I be concerned?

Plug in a scanner and pull the code.

What exactly were you doing when it came on? Any wheelspin involved?

I would be mildly concerned. If it comes on again, I'd be more worried.

In most cases when a warning light flashes, it means that the software has failed, and is the most serious problem to have, hence the flashing to alert you. If check engine light or ABS light is solid and doesn't flash, it means there is a problem, but it is not a vital emergency. Fix it soon.
The flashing light is warning that a major component has failed, usually, the PCM or main computer or the ABS computer. It is the truck's only way to have you understand and make a appointment to repair the problem, as it is telling you it is serious.

Since your light went out after you turned off your Taco, you did the correct thing to reset the system if it is a false report. Sometimes computer go crazy, I know, Hard to believe. You did do the right thing by stopping and reading and then restarting. I would not worry unless your flashing light returns in a day or two.

I was just driving down the highway when it came on.

Thanks. That's what I thought. I've started the vehicle 5 or 6 times after that, and driven about 120km and it hasn't came on yet. So I'm hoping it won't come on again.

just a thought, when was the last time you serviced your brakes?
now this is not a warning that your pads or shoes are worn, but one easy solution could involve the brake fluid. brake fluid should be changed on a reg. schedule esp. depending on use. if your brake fluid is dark CHANGE IT.
water and trash builds up with time esp. water and this could set of the abs sensor. I have read several good articles on this over the years since abs came out, and one is that people who drive almost all there miles on the highway should flush there fluid every two years since repeated braking makes the brakes hot which by theory boils off moisture in system, but you dont get this on highway miles, hence moisture buildup.
stop and go city driving cures this but with all the braking you get a buildup of dirt.

Definitely check the fluid level then. It might be low.

If it's the fluid level, shouldn't the "break" light go on, not the abs one?

not always. if the fluid is low or dirty, this can set off the ABS light first.
they are very sensitive to the condition of the fluid. it the dirt or moisture that can cause them to fail. its always best to just do a complete flush when doing the brakes. they can be a pain in the ass and expensive if the go bad.

and if you don't mind, one more thing, if you can get DOT4, brake fluid I woud use it, (its what I use.. its a step above the standard, and in the extreme weather, (swing in temps) it give extra protection and is just a little more. and one old trick is to get a cheap turkey baster, suck out most of the old dirty brake fluid in the master cylinder, fill with good, bled brakes till the fluid is clean, (and you are not running so much of the dirty fluid back through the lines) and you are set.
