Abs Light On 93 C1500

[radiator]

Hello i have a 1993 chevrolet C1500 and when i turn on my ignition mymy ABS light does not come on. I have never seen it on. so i was just curious if it is supposed to come on with the ignition or if it is burned out.

 

Thanx

It should come on for a few seconds then go out.Might be burned out or the fuse has been removed.

You test it using the diagnostic connector under the dash. All you need is a paperclip

Thank you. The fuse is there and is not blown so i will check the bulb.

Here's what Hawkeye was talking about.Once you have the jumper in place turn the key on,but DO NOT start the engine.The ABS light will start flashing...count the flashes.The first should be a 2,then another #.That will be your code.Then you can Google it
