WARNING: This page is about a different car, the 2010 GMC Sierra and 2010 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Find out from the customer the conditions under which the DTC was set. This information may help duplicate the failure like the specific number of brake pedal applies in a row prior to the fault set.
Check for hydraulic leaks, air in the brake system or an improper brake bleed.
