ABS and BRAKE lights

Take an have code's checked , do you know what those are ? DTC'S - diagnostic trouble codes stored in the abs control module . Anti-lock brake system , wheel speed sensor . nothing to do with base brake system .

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

The person you have checking your vehicle is a parts replacer. Not a mechanic. He's just hoping to hit it right, eventually. Have someone check the sensors at the rotors my friend. Most likely one is out of position and not picking up the proper message for the computer. Yes, once the light is out, from all the other work he's done, it will come back on each time. That's just the nature of the beast. If it is just a sensor at the rotor out of adjustment, the light wont come back on.

Have someone scan the body computer for trouble codes.
Once the problem is fixed and the codes are erased, the lights should stay off.

Someone needs to access the body computer with a scanner to clear the code or codes and turn the light off.
You may be able to disconnect the battery for an hour or two and do it.

2009 avenger, ABS and brake lights stay on, cleard codes still came back, had dealer clear codes, still came back. dealer says its a speed sensor,i replace all 4, then he tells me its the brakes i have new breaks put on, now he is telling me its a fuse, i checked all fues's, nope not it AGAIN, now he says its the ABS sending unit or the ABS modutaltor and he said if you replace one better replace both, now they want A NOTHER 1300.00. can ANYONE HELP ME

Hi I dont know weather this will couse the problem,but you should always clear the codes when you have done the work that the codes told you abaout in the first place.
personaly I would get the codes cleard first before looking into the other stuff.
hope this was some help.

you must re-bleed the system properly, especially the back brakes. Bring your vehicle to a local autozone to reset the ABS light or check for an ABS fault code and post it on fixya!!

I think it means the Antilock Brake System is disengaged. So, a code has been stored in the abs computer. Standard obd tester cannot check these codes, must visit your dealer or some autoshop with ABS reader.

According with the service manual: During starting the RED brake light should briefly come on and then go off. If the RED light stays on, it indicates a problem in the main braking system, such as a low fluid level, or the parking brake is still on.

Hope helps (remember to rate and comment this).

You may need to make sure that Ford Factory pads have built in sensors on them. In many vehicles these built in sensors will cause the abs and brake lights illuminate when the brake pads wear down to a certain point. Also make sure to check your brake fluid regularly. I used to work for a Infiniti dealer in the service dept. When the brake fluid was low it caused the brake lights to come on as well. Just a few things you can check out yourself before taking it in to the dealer to check for codes.
