DTC P0000: The main cause of DTC P0000 has to do with the scan tool in
use. Some aftermarket scan tools are simply not equipped to read certain
systems, protocols, and manufacturer-specific DTCs. As such, they default to
display P0000, which can be a bit misleading. Update your scan tool software,
make sure that it's fully compatible with your year, make, model, and
sub-model, or see if you can access an updated factory scan tool.
