Re: abs not working
Its the clear problem of wheel assembly.in this case wheel assembly has to be replaced.as the sensor in the present wheel assembly is proper so its showing the noise below 30mphbut the wheel assemblky is faulty so its not working.no need to reprogram as this is not possible.replacing the wheel assembly is necessary to solve the issue.

Re: abs not working
U need to find out if the sensor is giving out a signal, the problem may be the the exciter ring on the hub or the wiring to the sensor or the air gap at the sensor, measure the air-gap at another wheel sensor, carefully check the wiring to he sensor, u may have pulled a pin loose in the wiring harness connector shell or broken a wire inside the insulator cover (do a continuity check) when u damaged the sensor. also was this a factory part? last disconnect the battery for a few and clear the code.

try putting one wheel of what you want to do on a hub to see if it fits
check for stud pattern and that the studs fit in the center of each hole
next measure the distance from the rim edge ( use a straight edge across the diameter and measure from that edge to the stud holes are ( measuring rim off set)
if both wheels measure the same then they should fit
go to a tire dealer and get the details of each rim to see if it can be done
the major items to be aware of are the stud pattern is the same pitch circle diameter ( bolts in the same circle ) and the center off set of the rim
Ball stud castle nut, tighten the ball stud castle nut to 22 ft. lbs. (30 Nm), plus 135 degrees
Note: Do NOT loosen the ball stud nut in order to align the ball
stud nut slots to the ball stud cotter pin hole. If necessary, tighten
the ball stud castle nut in order to align the ball stud castle nut slot
to the ball stud cotter pin hole. Ensure that the cotter pin ends do
NOT contact the ABS wheel speed sensor, the ABS sensor connector or the
NEW cotter pin and bend the ends
Stabilizer shaft link
ABS wheel speed sensor jumper harness to the harness retainer clips
ABS wheel speed sensor connector
Lower control arm nuts, tighten the lower control arm nuts to 71 ft. lbs. (96 Nm)
there is no resetting of the ABS light. it means there is a problem somewhere in the ABS system. There are sensors by each wheel - they seem to be sensitive to moisture - they may have failed for the ABS sensors. the traction control light may be related to the ABS light. just check it out ! make sure there are no brake fluid leaks at the wheels, and be sure master cylinder is full of brake fluid. In most cases a scan tool is necessary to access the stored fault codes. good-day !
The only things you have to take off is the tire and the brake drum, which comes off just by pulling it off, it may need a some effort, if too tight, hit it a couple of times with a hammer, (not too hard) to loosen it up.
The sensor is bolted to the backing plate in front of a toothed wheel which is part of the axle shaft, right behind the wheel studs.
Note the position of old sensor and install new one in same place.
The way the Brakes work on your Colorado, if there is an issue with your ABS, the brakes will still work. You may just not the have ABS brakes active. Most common cause of the ABS indicator is a faulty sensor to one of the 4 wheel. the common ones are the front wheels. Inspect the ABS sensor lead wire which should be along the A-arms to the ABS sensor on the inside wheel hub. Spray brake parts cleaner to the sensor and speed ring to ensure there clean and free of dirt that may be hindering the sensor to read the speed ring on the hub. Look at the condition of the lead wire and inspect for corrosion or any other type of damage. Most of the time a good spray of Brake parts cleaner will fix the problem. If there is an Auto Zone around your area, buy the brake parts cleaner there and have them scan the truck for the DTC codes which would indicate that it is the ABS sensor and not the ABS module, which will be costly and your most likely run it the way it is without ABS due to cost of replacing the module. Good luck friend.
It sounds like you may have a bad ABS sensor. Best thing to do is check all the wire harness from all the wheels for cracking or breaks. The sensor could also need some adjustment, not sure how it is on the Colorado. There are some ABS sensors that is a part of the wheel hub and just dubble check the wire harness since the hub is going to be replaced = expensive. If it's a ABS sensor that counts the rotation from the wheel hub then it's adjustable.
The sensor may have moved out a way from the ring counter and may just need to be moved closer to the ring which is a part of the wheel hub. Most of the time a good spray of Brake cleaner will fix that. Just follow the the ABS wire leads to the hub and you should see the sensor. Be surprised on how much dirt can collect back there.
Good luck and hope this helps, If you can get to a auto parts store that will scan for free like Auto Zone. The ECM may even have the information to which wheel has the bad sensor reading. At worst, it's your ABS system it self that may be going bad.
RAVE says the following: 1) Release ABS Sensor harness grommet from inner wing valance and disconnect multi plug. 2) Raise front of vehicle. 3) Remove road wheel. 4) Pull ABS Sensor harness through aperture into wheel arch. 5) Release harness from brackets on inner wing valance, suspension turret and front hub. 6) Release stake from drive shaft nut 7) Remove drive shaft nut with assistance & discard. 8) Remove front brake disk (Remove calliper, pad holder, screw and tap to remove) 9) Remove 4 bolts securing wheel hub to steering knuckle. 10) Release wheel hub from steering knuckle then remove wheel hub and drive shaft assembly from axle. DO NOT REMOVE ABS SENSOR FROM HUB. HUB AND SENSOR ARE SUPPLIED AS AN ASSEMBLY. 11) Position the wheel hub and drive shaft on a press, place supports beneath the wheel studs and press the drive shaft from the wheel hub. 12) Remove drive shaft oil seal from axle casing.
Refit is mostly the reverse, you need to take care to lubricate things in the right places and put loctite on the drive shaft and locate the loom and torque everything right.
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.
