Abs light coming on

Any dash light that flashes or stays lite, is a
possible system fault

Shouldn't be using it

You should check for codes & have the vehicle
diagnosed within days, of any Malfunction Indicator
Lamp coming on,on all vehicles

You have a possible ABS Braking System issue

Well u have to check brake pad sensor or brsk fluid level first

Short in battery cell or bad connections or the alternator is going bad. Have it fixed before you fry the computers in your car.

IT COULD ABS RELAY OR FAULTY ABS UNIT CHECK BRAKE FLUID LEVEL.BE BEST TO LET DEALERSHIP CHECK IT OUT.THEY HAVE SPECIAL SCANNER TO TROUBLE SHOOT IT.

Check to see if the plugs on the wheels are plugged in check that the pins are all the way into socket, that your ABS problem, next check to see if you knocked loose the wire on the differential most likely cause and be sure to top off power steering fluid. Check that the fluid level is ok on the Diff. if you need more help let me know and thanks for using Fix-ya and rate if this was helpful.

need to hook up a scan tool to read the codes,it will tell you what is making the lite come on. Could be the trailer brakes causing this.

maybe the ground wire on one of the sensors fell off, or is loose, check the abs sensors.

looks like you have a faulty sensor (ABS) check all conections on hubs you may have disturbed something when you changed your brakes hope this helps

Check your abs connectors they might have pulled a wire loose

The back up lights are turned on by the transmission range selector switch, this is the switch that moves with the gear selection arm at the transmission, unplug the switch (large multi wire connector) and if the backup lights go out the switch has shorted and needs to be replaced, one question why don't you just remove the backup light bulbs until U install the new part??
