First try reset procedure:--- To reset the ECU , disconnect the battery negative terminal and plug in back in 30 min.If itys not helping then,ABS Modulator and Accumulator.This are the two parts which can cause this problem. The modulator is the unit responsibile for "pumping" the brakes for you. Attached to it is the Accumulator, which is a metal cylinder which holds the high pressure fluid on standby when your car is on.----------
Get the brake fluid and brake lines checked.If the brake fluid is low, this problem can occur.If the brake line is blocked this problem can occur. -------- Also get the wheel sensors checked.When this sensor fails you will just not have abs brakes you will still have conventional brakes . You should be fine to drive it to the shop to have it fixed unless it's running rough or transmission not shifting correctly.The ABS sensor needs to be pressed out and replaced.Most probably your problem is abs wheel sensor.this sensor is got shorted. and its causing the problem.But if sensor checked out ok, then get the ABS module scanned.In scanning the error code will be retrieved and as per that error code you can replace the faulty part.------- This should help.thanks.Helpmech.

Hi I would like to know how would I go about adjusting my 1999 polo playa 1.6i clutch cause it is to high can any1 help thanks 4 your advise


'Volkswagen Polo 1.9TDi 74KW, 2006 model sedan. Instrument cluster will reset, all lights come on sometimes with a loud beep sometimes with the horn also. It started first when I turn steering wheel to max either side then the airbag light will come on and I will loose power steering, then when switch off and restart all is fine but all counters are reset on the instrument cluster. Most recent incident when I was driving on highway and slacking off to take an exit then all the lights on dash was lit, lost power steering and loud beeping and I switched off engine and restarted (while freeing at high speed) then all OK again. Seems to happen more frequently but intermittent.' - has been answered - "'I had the same problem after I had my car serviced, the problem with the power steering was that the signal to the power steering pump was set to high and the pump cut out because it was receiving an incorrect signal, the instruments reseting was found that alot of the ground wires was loose, for some reason the abs sensor was also not adjusted correctly which made the abs light come on as well. I took the car to another service centre and they adjusted the abs sensor and the signal to the pump and checked all my wirring - had no problems since - Christiaan from South Africa'"

What do i do when the anti brake like has just come on. and what does it mean when the trac light is on?


ANY TIME ABS LIGHT OR TRAC LIGHT COMING ON THAT MEANS EITHER ONE IS NOT WORKING NOT GETTING NO OR ENOUGH POWER.CHECK ABS FUSE AND RELAYS. IF RELAY AND FUSE OKAY.MAKE SURE YOUR ALTERNATOR VOLTAGE OUT PUT AT BATTERY SHOULD BE 13.5 TO 14.5 VOLTS IF 11.0 VOLTS DUE TO VOLTAGE REGULATOR FAILURE. THAT WILL CAUSE ABS AND TRAC LIGHT TO COME ON.IF ALTERNATOR CHECKS OUT OKAY.TAKE VECHICLE TO GARAGE OR DEALERSHIP THEY HAVE TO SCAN THE ABS BRAKE SYSTEM.

ABS light goes on and off


Sounds like you have loose brake pad linings.
The traction control measures rotational speed between each rear wheel. If your pad lining momentarily causes one wheel to hesitate your trac control will flash. As the ABS detects braking without the brake pedal being pushed, it will flash.
Check your emergency brake pads. They can fall apart inside the drum/rotor combo on the rear. That is where your sensor is for the ABS.

Abs and trac light on, abs vibrates car when braking


These two circuits are linked together and you probally need a ABS MODULE and possibly a rotor and they are pretty cheap on e-bay

2004 Cavalier, Service light, ABS light, Trac Off light


Are you using a gel based battery?
Sounds like an overload on the charging system screwing the whole electronics of the car.
If not - get it diagnosed at a dealership.
Sorry.

Vsc & trac off indicators


Have you scanned both the engine computer and the abs computer? Because it is an abs problem, likely a wheel speed sensor.
