Conditions for Clearing the DTC

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The conditions for setting the DTC are no longer present (the DTC is not current) and you use the scan tool Clear DTCs function.
The current DTC clears when a DTC sets which directly indicates a brake switch or master cylinder pressure sensor malfunction.
