    Well after a few days of continued driving then I went to take it to a parts store to erase the messaage and there was no messages to clear. I guess this means it was just a glich fault unless it comes back. I spent a lot of time on the internet looking for a less costly soulution that to take it to the dealer. I just went throught this with a different message of P0171 "lean air on bank 1" For that I ask the dealer what it would would cost and was told about a little over $200. I found out (on the internet) that 95% of the time it was a intake gasket. I went and spent $5 for gasket and had it changed in 45 minutes. I am finding out that these cars ECU messages are huge money makers for the dealer manitenance side ot the business. Thanks for all the help !

SOURCE: 2005 toyota prius abs brake not working warning

Hmm, I'm not sure what a main chip is but, there is a few reasons for this problem.

  1. ABS Sensors - there could be something wrong with a sensor and/or the wiring to them
  2. The wheel bearing speed sensor in a wheel is bad or intermittent which then tells the computer that wheel is traveling at a faster or slower rate of speed then the rest which in then the computer turns the abs light on.
Now when your warning lights go on, the computer sets a DTC code which is the key to helping solve this problem. If you can get the DTC (Data Trouble Code) from the dealership or from someone who can scan your can, I can better assist you in figuring out what's wrong. Hope this helps.

SOURCE: 2005 Toyota Corolla check engine light on.Fault

Hi
Could mean there is one fault causing many faults, example, Air mass sensor, this can cause rough idle and over fuelling so the code reader will just send it back with undefined as there are to many faults to identify as the cause.

Most likely it will be a air fault so check the air sensor first, try cleaning it with carb cleaner, sometimes works. If not get back to me could be 2 other things. although the car will not drive very well if it is any of the other 2.

Regards
Dan

Thanks for choosing FixYa and welcome. You need to check the brake switch. Your brake pedal contacts the brake switch when it is pressed down. There is a small button on the brake switch that activates the lights. It may be stuck or broke. Try to loosen the button first. If it won't, buy another one. They only cost a few dollars.

Abs brake light is on-why


This means that something is not working correctly on the brake system (anti-lock Brake system) There are code readers that you can use to access the error codes. They connect to the obd 2 port on all cars. You can buy one or you can go to any chain autoparts store and they will read the codes for you for free.

What does it mean when stabilitrak and abs light comes on. Once this happen a few minutes later when I brake it makes a grinding noise.


Same as with ALL vehicle problems---
when you have a check engine light on

You stop using it
Check for OBD Codes
Diagnose your codes
Component test-- to find a problem
Make the repair

With or without codes-- you can Google
ABS Braking Systems,Trac Control & many other
abs add-ons-- to learn about them

What about reading your owners manual !!

Fail to see how using a vehicle with
brakes grinding, would be safe

Brakes have to come apart once a year
when you have no problems

Brake warning lights


Many repair shops can read the ABS codes also - especially shops that specialize in tires and brakes.

The codes will likely identify if a specific wheel sensor is mis-behaving / failing, or a worst-case situation: the ABS Control Module is failing (expensive).

The sensors, located behind each wheel, can be checked for accumulated road 'gunk' and cleaned. Also look for any frayed/broken sensor wires.

NOTE: The sensor sit about .25" away from a gear-type ring on the backside of the wheel - the 'exciter ring'. It's the teeth passing in front of the sensor that creates the signal sent to the ABS control module.
NOTE: The ABS Control Module reads the speed of each wheel and 'pulses' the level of braking to each wheel according to if it thinks it is skidding on ice/wet surfaces.
Problem with the Anti-Lock Brake System. Take it to a professional and I believe it means the Antilock Brake System is disengaged. Means a code has been stored in the abs computer. Standard obd tester cannot check these codes. Take to dealer service shop.

1999 Olds Silhouette -- Problem - ABS & Brake Traction light "coming on" on the instrament panel. Brake fluid level "full". Brake pads & shoes "new". No brake fluid is getting to the REAR brakes....


The ABS light is on because there is a fault in the abs system, The traction control uses the abs system so it will also not work if the abs is not working. You'll need to scan the ABS module to see what code is stored in its memory. Once you have the code you'll have a better idea of what needs to be repaired.

My ABS light and emergency brake light comes on everytime I start my Ford Windstar, and they stay on when I'm driving around, even though my brakes are not on. Anyone have any idea what this means?


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).
