ABS light goes on and off

try scanning the speeds at low speed 5-10 mph and '
check connector for water or corrosion if ok it is probably
the sensor

u can try it-may work-somtimes just a glitch--if car drives ok dont sweat-brakes will stil work w out abs---------bring vehicle to a partstore fora free readout

Nope, but take it in. Brake problems are nothing to fool with They'll probabl tell you it's the ABS ECU. Not a cheap item.. However, it only affects the ABS system, not the brakes itself.

B1596 ABS Module Service Continuous Codes NOTE: If other DTCs are present, REPAIR them before installing a new component.
TURN the ignition switch to the OFF position and wait at least 30 seconds. Turn the ignition switch to the ON position. REPEAT the ABS self-test. If any DTCs are retrieved, REFER to the Anti-Lock Brake System (ABS) Module Diagnostic Code (DTC) Index. If no DTCs are retrieved, CARRY OUT a drive test above 15 km/h (9 mph), then REFER to the symptom chart.

So your problem right now is that the ABS/TRAC light keeps coming on? is this correct? and, is there any codes in the ABS Module?

There should be a history code in the ABS when that light comes on it has a code and it will store the code in the ABS computers history. Even if the light is off there should be an ABS code or codes in the history. Having that code or codes is where we need to go next.

Then, if the lights are coming on and it is NOT setting any codes. If thats the case there could be a power or ground problem to the ABS module.but the most problem I have seen with these is the wiring to the front sensors goes bad an intermitanlty will loose a front signal to one of the front sensors and cause this. But that would usually throw a code in it. 9 times out of 10 replacing the harnesses to both front sensors should do the trick (if we had a code and knew if it was RF or LF then we would just replace the wiring to the affected side).

The ABS light being on will turn off the anti Lock Function. You will only have regular non-ABS braking on your vehicle. O'Reillys Autoparts should scan your system for free, at least you will then know how much it will cost to fix. Hope this helped...

CHECK TO MAKE SURE WITH CAR RUNNING VOLTAGE AT THE BATTERY SHOULD BE 13.5 VOLTS TO 14.5 VOLTS. USE A DIGITAL VOLT METER TO CHECK VOLTS AT BATTERY. WITH ENGINE OFF BATTERY VOLTAGE SHOULD BE 12.5 VOLTS. IF NOT ALTERNATOR NOT CHARGING BATTERY.THAT WILL MAKE ABS AND BRAKE LIGHTS COME ON AND A FAULTY BRAKE LIGHT SWITCH WILL ALSO CAUSE ABS AND BRAKE LIGHTS COME ON.IF ALL LOOKS GOOD.HAVE THE ABS BRAKES SCANNED.IN THIS CASE YOU ARE HAVING BRAKE FAILURE.BECAUSE WHEN BRAKE LIGHT COMES ON THATS WARNING BRAKE FAILURE BECAUSE THE BRAKE MASTER CYLINDER AND ABS UNIT IS TOGETHER AS ONE.NOT SAFE TO DRIVE.COULD LOSE BRAKE CONTROL AT ANY TIME TOW IT IN.

there is a problem with your abs sensor ....sounds like the sensor is applying the breaks for you when it shouldn't ....have a mech. look at it ...the e- brake issue could be causing a fault in the system ....all the symptoms may be the car.s computer,s way of telling you there is a problem "please bring me in "

please don't GUE$$ this problem speed sensor is part of your speedometer!! not the ABS sensor located at cv joint sensor ring! the sensor is bolted or pressed on to you brake anchor ///hub but it could be your ABS pump?? it could be 1 of 4 of your ABS sensor switches it could even be the sensor RING on CV joint? so to GUE$$ would cost $100.00 up word to a $1000.00 so again take in get it properly scanned to retreve the sensor or other part at fault! usually the fee is waved if you do the repair at that destination! or reduce 1/2 price depending on how well of a relationship you have with your tech our shop usually waves it if you go ahead and get the work required completed! QUESTION is it dangers absolutely! your safety as well as inasint others well it is your choice I hope the free support I gave you helped you out some way shape or form.John
