This is an extremely common question that about two minutes' research will help you resolve.

Hello All. This is my first posting and it comes in the form of a question.

'00 Ford Expedition 2WD with Front and Back Disc brakes w/ factor tow package.

Problem: ABS light stays lit after a 1 or 2 second delay when turning key to cranking point.

Diagnosing Performed: Inpsected Calibers (no damage), replaced brake pads for all 4 wheels (very worn). Checked brake fluid (no leaks present from master cylinder to brake lines) The 50 AMP fuses is good. I disconnected the negative battery cable for several minutes to try to reset the system. (ABS light persistent)

I have not done much driving since replacing brake pads which may or may not be required for system to process the change.

I suspect a variable speed sensor, but I'm not sure if I have RWABS or 4WABS or the where they would be located?

If RABS, no front wheel sensors.

If 4WABS, you'll see the sensor harnesses.

Otherwise, look for my previuos posts.

umm are you talking about four wheel drive abs or rear wheel drive abs? have you also checked projectsho's previous posts? and last have you tested ontop of rear differential the abs sensor? seen if you get 1.0?

ok hope this helps bro,
Deltasoft.

 

Thanks for the quick responses to my comments posted. Would I have remove anything, but the wheels to get to the speed sensor(s)?

 

if your going to remove the sensor ontop of rear differential, then all you need is a wrench and unplug the sensor and put new one. PS: the new one cost me from ford, $20.00.

Goodluck, half of time is that sensor.

Was told that the driver side sensors was bad and I replaced both the rear and drivers side abs sensors and still the light stays on.. I disconnected the battery (pos side) to reset the system and still the light stays on. Can you reset the system for the abs light some other way???? Thanks

 

The ABS computer turns out the light when it passes its own self tests. You cannot turn it off.

You will need to have the ABS computer scanned to see why your light is on. It appears from your description that you have 4WABS which requires the proper scanner to pull codes. As these scanners start at around a grand, you'll need to locate a well-equipped shop that has the correct scanner or see a Ford dealer.

The codes does not give you a component to replace, it is a data point in the diagnostic process.
