My scan tool at my shop reads ABS codes...
Kinda off topic buy my stupid 02 Tahoe Z71 had an ABS code (changed all my rotors/pads/copper brake lines) and couldn't do the automated ABS bleed because of a bad sensor in the hub. Hooked the new hub up without installing it, did the bleed and returned the hub
Pretty sure I set some sort of record for bleeding brakes on one of these trucks too. Start to finish was about 15 minutes.
