On: 2004-2012 Chevrolet Colorado (first generation) · 2005-2009 Chevrolet Equinox (first generation) · 2007-2014 Chevrolet Silverado 1500 (GMT900) · 2014-2019 Chevrolet Silverado 1500 (K2) · 2007-2017 Chevrolet Traverse
Is it the ABS module?
Check the cheap things first: battery voltage and the main fuses for the ABS pump and module, the ground straps, the module connector (corrosion, a pushed-back pin) and, for wheel-speed codes, the sensor and its wiring at each wheel. If those are good and the code returns as soon as it is cleared — or the scan tool cannot talk to the ABS module at all — the module itself is the likely cause, and that is what we repair.
