Abs flashes on and off on dash then brake light flashes on and off brake lights flash when dash lights flash

The amber ABS warning light is telling you that there is a problem with the ABS system. When the antilock brakes don't work you just have good old fashion non antilock brakes. When the red brake warning light is on it could be a couple of things. (unless you are talking about the brake light on the back of the car is stuck on) the red brake warning light on the dash tells you when the parking brake is on and it also tells you when there is a problem with the hydraulic system. Some cars will also turn this light on when the brake fluid is low, (not sure if the Cavalier does this)

The ABS system is computer controlled and needs to be scanned for trouble codes to diagnose the problem.

I can't say I have ever heard of a "brights" indicator flashing, Do the headlights go bright and dim as it is flashing? Is it a slow on and off like a turn signal or faster than that?

your alternator is going. have charging system checked, but sometimes the test will pass but barely. your alternator is on its way out

cant by pass problem with abs brake see lights flashing there is a problem with abs brake system need fixing could have brake failure.

Do you have a ABS Light at the same time?

Use the instrument brightness control to adjust the dash lights. If the brake light is on, release the emergency brake. ------------------------------------------------------------------------------

ABS light is on because brake light circuit is down. Did you replace the park lamp fuse? Check trailer light connector if you have one.

Any time the ABS light is on the ABS system is deactivated. The brake system should still function normally since the normal brakes do not rely on the ABS system to function. The only thing you will notice is that the brakes will lock up under a hard or emergency braking situation. My personal thought on this is at least find out why the light is on. If it is a relatively inexpensive repair that the added safety of the ABS system is well worth it. If it is a expensive repair that you'll havue to way the options. Under .the passenger side of the dash or behind the passenger side kick panel you will find two connectors not connected to anything. One will have three wires and one will have two. With the key off jump the two terminals of the two wire connector. Turn the key on and count the number of times the abs light flashes. It shoul be a series of long flashes and short flashes. The long flash is the first number of the two digit code and the short flashes will be the second. Post the codes and I will try to help you further.

we have 2002 passat tdi auto...the brake light on the dash has started flashing when we put it in park with a kind of clicking noise. any ideas?

Have the ABS system scanned for codes. The ABS and Traction control use the same computer. You likely have a bad wheel speed sensor.

Check your abs connectors they might have pulled a wire loose
