The ABS light on the dash comes on when I drive my 98 Ranger XLT. What could be the cause of the kight comming on? I am not sure if it has 4 wheel ABS.
Any help where to look would be appreciated.

Thanks

It means there is a problem somewhere. Need to get codes pulled to know whats going on. First step, I would confirm you still have fluid. Then either borrow or buy a code reader or take it to autzone to find out whats up!

 

not sure but i had the same thing happen on my 93 ranger and had to take it to the dealer to have the code read. Ended up being the abs valve under the driver side door on the frame.

 

Requires a special code reader to read and diagnose the ABS codes and not all mechanics have the capability. It is not the same scanner used to read the OBD II codes.

 

I thought it was tranny codes that were different, but the abs codes were the same reader as the basic codes? Sorry for the misinformation!

 

I wish that was the case. Plus the local Autozone advised me about a month ago that their corporate HQ has issued new policy and they no longer are allowed to pull codes for customers. I am curious if anyone else has come across this.

 

Welcome to FTE.

If it's the ABS warning light thats on, it indicates that the computer has disabled the ABS function & reverted it to normal braking.

It could be a number of things, so we'll need some more clues to make a better guess as to whats wrong.

Are you having any other problems, like an unsteady speed-o, or the cruise control acting out, or the auto tranny shifting acring up, if so, suspect the rear differential mounted ABS speed sensor, it's wiring for chaffed insulation back where it comes out of the plastic sheathing, or electrical connector.

As all of the above listed things also use it's output PID to the computer, if it's output is corrupt, they'll act out too & it's a commom problem part.

If you have 4WABS, check the front wheel speed sensors for debris, or damage to the sensors, electrical connector or wiring, especially for metallic debris on the sensors, or for chaffed wiring insulation.

If that doesn't pan out, check the "Tech Info" thread atop this forums thread listing page, for a "how too" on pulling ABS codes yourself, or maybe run it by a brake shop, or Dealer, as they'll have a high end scan tool that'll pull the ABS codes, but they'll likely charge for it.

Raise the hood & look low down on the drivers side inner fender below the brake master cylinder to find the ABS motor & count the brake lines coming out of it, 4 lines = 4WABS.

Checking your brake fluids level & condition as suggested, is always a good idea, especially if the brake warning light is on too, or if your also having a low or soft pedal.

Did this problem come about after some event????

A bunch more things for pondering, let us know what you find.
