2004 Chev Colorado Z-71 4WD ABS "chatter"

I have a 2004 Chev Colorado Z-71 4WD. Would mud & dirt cause the ABS light to come on? Once in a while I feel the brake pedal "chatter" at low speeds. The light came on once and I reset it. Is the ABS sensor for the rear located near the rear of the trans. ?

Why would the abs light be on?

Each wheel has a magnetic sensor and a slotted ring that generates the ABS pulse. The sensor can get dirty (rust, mud and brake dust) and have to be cleaned. The replaceable slotted ring often rusts in older cars. The cable from the wheel sensors to the body, while very tough, can get damaged or disconnected. Its usually the front ones.

You may need new rotors.
Subarus requires the same make and size of tires front and rear. Mixing sizes can cause a mismatch in the ABS signals from each end, and this will often cause the ABS light to come on.
The ABS computer may have failed.

If ABS is working more or less correctly, hitting the brakes on loose dirt or snow/ice should result in the pedal kick back and the buzzing of the ABS valve system.

Abs fault lights up on dash and feels like brakes are dragging constant

I had a 96 tahoe and my abs light was on and my right front brake was dragging, i found that it was the abs speed sensor that was causing the problem. Once i replaced it abs light went out and no more drag. I know there's a big year diffrence here, i dont think the way this all works has changed much. Hope this helps.

My rear end chatters around corners and if im pulling a trailer my abs light and the wrench shaped light will come on in my 2004 f150 fx4 supercrew

If you have a locking rear diff,it could be the clutches on the side gears or lack of fluid and special additive. Sounds like the wheel speed is off enough on corner,to set the ABS light,when it chatters. Don't over look parking brake and rear caliper issues.

What is causing the abs fault light to appear.

fluid level sensor is a possiblity, but being your pedal feels odd it could be master cylinder.My suggestion would be to have the codes pulled to narrow it down

I have a 2004 Chev Colorado fan only works on #4 speed.

The fan speeds are usually 99% corrected by changing the fan resister board....usually near the fan motor under the dash in front of the pass seat.Cost .......around 30$ for the board.You can do it.
Follow the wires from the fan motor to the board connector.

My 2006 ford f-150 abs indicators is on and im unsure why?

D, not much to go on here. But a shot in the dark, Several things can make the abs light pop on. Been in mud lately? The wheel speed sensors can get full of mud. Some people use a high pressure washer and that may knock the sensor out of position. The abs light comes on for a bad sensor which should code. If you had brakes done recently make sure they put the correct rotors on. Happened to someone I know. Wrong rotors and the light wouldn't go out. I hope its just mud and dirt. Check the rear sensor and make sure it nor any others on front came unplugged

Abs fault

check and make sure u did not damage or disconnect the wheel sensor(s), that would be just about the only thing u could have done to cause this issue, u might want to have the system tested for trouble codes to confirm this wheel sensor possiable fault.

Abs light

This is a (4) four wheel sensor system and more than likely one of them has failed. This will cause ABS module to turn on warning lamp and make the brake pedal 'act up' under the right conditions.This 'acting up' is the ABS system getting a false signal that a wheel is not turning the same as the others when it actually is. Have it scanned for codes and a streaming data scan on a road test under the same conditions that you are experiencing the 'act up' to pinpoint the fault. Hope this helps! Please rate me.
