Question about 2004 Ford Focus
My abs light stays on on my ford focus
When the ABS light stays on it means there is a fault present in the ABS system and the ABS has been disabled, as long as the light is on u just have regular brakes with no ABS, there are many thinbgs that can turn the light on, most common is one of the wheel speed sensors is defective, since these sensors are about $75-100 each and there are 4 of them guessing is a poor idea, so what u need to do is have the ABS systwem tested, there will be a fault code present to help narrow down the defective part or wiring.

The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

most likely a wheel sensor concern
if the computer cannot see the wheel speed then you lose ABS and TRACTION control
go to almost any part store and have them pull codes
assuming you have a VSS code, replace the suspected part or continue diagnoses for possible wiring concern

If you paid good money to have it fixed at a FORD AGENT then take it back and tell them that you are going to wait for it and dont take any **** from them as all work done by a Ford agent will be under warranty so if its still in warranty time take it back, or tell them your take it to the papers and let them tell the world..
It works belive me.
Let me know how you get on . RON

You need to get a diagonstic check as sooon as the light comes on, dont turn ignition off as thi may delete the fault code Good luck Davelee
