2007 ford edge, three lights are on: ABS, wrench

It means you have a Anti-lock brake problem an DTC'S - diagnostic trouble codes are set in the EBCM - electronic brake control module or could be a Transmission problem or the electronic throttle control problem . Having these code's checked would be a good first step . The dealer or someother qualified repair shop .

Did you have the codes erased after repairs were made ?

If they all come on at the same time, chances are its a problem the engine computer has found. The wrench is a warning light for the engine and transmission, the ABS and traction control involve both the drivetrain as well as the brakes. So if a problem pops up in one system the computer knocks out the others too.
Have the main computer checked for trouble codes and go from there.

did you replace hub bearings.

the most likely cause is a faulty wheel speed sensor,
there are four,one on each wheel.
you will need to plug in a diagnostic tool to determine which one.

Your ABS and traction control use the same sensors. one is probably knocked out of alignment or bad, and it takes special equipment to get them right. Take it to an alignment shop, as they are cheaper than dealerships if you don't have warranty left.

Have Wheel Speed Sensors checked

If you have a weak battery, change it, the electronics on a P38 are a nightmare,
I have had my share and still have them, good luck

You most likely disconnected the wireing harness. Check the plugs at the brakes.

You need the codes read that are stored when these lights come on, that is the 1st step.
