I dont understand why you are doubting us??? I know it`s not cheap to have it scanned, but it`s also not cheap to replace a BCM either....
I own 5 GM vehicles. I`ve never yet had an ABS and Trac light on that wasn`t one of the wheel bearings gone bad (Ive had a problem with the ABS unit itself causing both lights to light). It`s possible that the BCM is defective, but until someone scans it, how will you know? If the BCM is bad it will show on the scanner. YOU CANNOT VISUALLY CHECK THE SENSORS IN THESE HUBS! They are 'sealed' inside the bearing assembly. Dirt on the outside if the housing means little.
Once again, a pocket/hand held scanner WILL NOT scan for ABS or SRS problems.
I hope you find your solution.
