SOURCE: ABS and TC light is staying on. Have replace hub

air gap at the abs module,is adjusted to far from the rotor, find which one is to far out and re adjust it.the deog mch should spot which one is out but not every time, you have to guess, or make adjustments on all wheels, the thickness of a match book cover is pretty close adjustment, but not in all cases.

SOURCE: CHECK ENGINE, ABS AND AWD LIGHT ON AFTER WHEEL HUB

you may not of plugged in the ABS connector.

Check engine light could be you left something unhooked also. The code will tell you what component.. Or you may of cycled the key with something unplugged before the job was done..

Have a 2004 gmc yukon getting codes c0040, c0550,c0455,c0296 in the abs computer. Trac and abs light on as well as suspension control.


C0040 - Right Front Wheel Speed Circuit Malfunction
C0550 - ECU Malfunction - internal write / checksum malfunction
C0455 - Either:
  • A bent terminal or poor connection at the SWPS may be one possible cause; or
  • The vehicle stability enhancement system (VSES) electronic brake control module (EBCM) calibration may be the other possible cause.
C0296 - Transfer Case Delivered Torque for Stability Control System Circuit

Abs codes c0040 and c0041 front wheel speed control sensor and circuit


Will be located near the wheel hub. As long as there is no physical damage I would guess you will be replacing the sensor

Why is my awd disabled light and abs light comming on?


Most common repair to solve the AWD Disable light problem is replace flow valve on the rear differential and also replace 4 pints of VersaTrak at the same time. (I'm a retired GM engineer.)

Abs code c 0036,front left wheel speed circuit range / performanc


I agree that it is more then like the the hub bearing assembly that also houses the speed sensor I would first check that there is no damage to the wiring that goes to the hub bearing that could be easy repaired, or debri that has been caked in between the sensor & the hub, use an air preesure to clean it out. Hub bearings are very expensive, so try this first. Good luck

HOW TO REPLACE OR REPAIR WHEEL SPEED SENSOR


It is part of the bearing hub assembly.Very have to do without air tools,If setting multiple abs/tc code (wheel speed sensors) probably abs electronic module or chaffed wires on drivers side at ac lines by air box.Have big problems with this and probably will come back.

Buick rendevousz headaches


I own the 2002 Buick Rendezvous CX and I've encountered the same problems listed here. The ABS / Traction Control Lamp stays on and was throwing a code for the left wheel speed sensor as well as an anti-lock brake code (both in the wheel bearing hub assembly). I replaced the left and right front wheel hub assembly yet this did not eliminate the abs codes. 
Ultimately, I traced this problem to a break in the wire that leads to the left hub assembly. Although the sensor was properly connected, the wire (which is encased in a plastic housing) was broken. This is the wiring which leads from the abs wiring harness under the hood down to the left wheel abs sensor. 
I would suggest that you simply remove the left wheel and inspect the wire that leads to the abs sensor (there is only one wire on each wheel). Mine literally fell apart when I removed the plastic housing around the wire. I spliced the wire together and put it back in the plastic housing. After this, my abs codes disappeared and my anti-lock brakes began working again!
This is a simple fix that many people spend $1000 + on by replacing the hub assembly which does not fix the problem.
