Unfortunately, it's going to need to go to a dealer, or an approved Volvo shop that has the proper computer to reset it.
If you have a friendly local shop around you who's approved and capable, they will probably do it for next to nothing.
When you replaced the ABS sensor on the hub, did you clean and re-gap the sensor to the speed ring on the hub. There was a recall on the ABS Malfunction on your truck. The tire size don't make a difference to your ABS as long as all four tires are the size, There was a issue bulletin with your Tahoe on the ABS activating under 8 km/h. Good luck and hope this helps, if not clean out the sensor with brake parts cleaner and check the wire harness and ABS sensor bracket. Re gap the sensor to the speed ring hub. Here is the bulletin. Anti lock Brake (ABS) Activation at Low Speeds (Clean Wheel Speed Sensor Mounting Surface) #03-05-25-007C - (05/16/2006) 2001-2006 Chevrolet Suburban, Tahoe, Silverado
I had the exact same problem!On the third battery and the third time in our local Chevrolet Garage...they told me they couldn’t find any problems. My response was, “this vehicle isn’t dependable and it’s staying here until you fix it.” Well what do you know about a week later and a $100 deductable on my GMPP warranty they found the problem. It was an accumulation of three issues but mainly one. 1.The LoJack system that a different Chevrolet Dealership installed was drawing a constant 20mA when the vehicle was off.Within LoJack specs. Normal. 2.The Prodigy trailer brake controller was drawing 15mA. Within specs. Normal. 3.And the MAIN CAUSE of the whole problem was the HVAC controller never turned off. It was continually drawing 35mA until they pulled the fuse. They had to order another HVAC controller which would have cost $287 and a weeks’ worth of shop hours to investigate the problem. Thank GOD they only charged me the deductible on my warranty.
I just recently had the same issue. Have someone check all the fuses and see what is drawing the power down. Do you have electrical seats? OnStar? Also have someone check your ingnition to see if it is fully turning off. Trailblazers are supposed to have the 'run down protection' but something that drains your battery little by little could be the problem. It seems that trailblazers need a lot of juice just to get started...
