02' Chevy trailblazer "ABS" light

I have a 02' Chevy trailblazer, on Friday I was leaving work and when I tried to stop the breaks started to grab like I was slidding on ice but there was no ice and after It finally stoped I took off and shortly my "ABS" break light turned on. I switched it over to Aw4w and it will sometimes shut off and if it does when I try to stop the breaks grab and it turns back on. I have no idea why it's doing this so if anyone can help I'd appreciate it.

It sounds like you have a bad wheel-speed sensor and the ABS computer is thinking a wheel is locking up when you try to stop and engaging your ABS system.

    Is there any way to actually find out for sure it's that?

    Yes, but you will need to get the vehicle scanned with a scan tool that will talk to your ABS computer. Unfortunately the scan tool that is capable of doing this is quite pricey to purchase, cheapest one I have seen is around $240.00 I suggest you take it to a shop that can scan it for you, then once you know what the problem is you can decide if you want to fix it yourself or have the shop do it.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .

• DTC C0040 Right Front Wheel Speed Sensor Circuit

I can't start my 2002 chevy trailblazer after battery change. my keyless entry is damage and i fear it is the anti theft security system not allowing it to kick over, any suggestion to start?


Is the security light flashing? If it is, put the key in and turn all the way but don't start. Leave on for 10 min. Or until the security light stops flashing. Turn off and then try to start.

ABS under 10 mph goes off...feels like we won't stop!


Like the other person mentioned, if you have a faulty sensor or bad connection, that would trigger the light. That may also be triggering your ABS to kick in when it doesn't need to. On each wheel, there will be a sensor with some wires coming out of it located on the inside of the axle just behind the rotor. You'd have to test each sensor to determine if one or all of them are faulty.

ABS, Brake Light Are On


ABS is near the breaks when you take the tire off and the break pads you will see it it is very small part that is a sensor. mine went on my car when the guys were putting my breaks on it it really has not made to much of a difference in the breaks. they are costly so I just deal with the ABS light for now til summer

2005 CHEVY +TRAIL BLAZER ABS AND BRAKE LIGHTS ON


if chains caused problem and you have driven with them off light would have gone out once it saw everything working properly. look at sensors might have pulled a wire loose with chains. the abs system runs a self test everytime you start vehicle if it sees a history code from last time it will leave light on and look to see if that problem still exists and 99% of the time it will cut light off . but need to have scanned and checked out
