You REALLY don't want to do this on anything newer than 2013 or so.
It works on the older vehicles but on many newer ones it will cause 
multiple issues depending on the make. Everything from minor relearns of 
radio and idle control to a complete shut down of the vehicle that 
requires a dealership to unlock and reflash components.

It is a much better thing to use a scan tool and figure out what the 
issue is then go from there.

Another thing on any vehicle newer than 2017 is that they now have 
security gateways in most of them which will prevent access with scan 
tools that are not OEM approved. This can make it really hard to access 
them.

Oh and if you decide to add a programmer or power chip on many of the 
new vehicles, hope you are prepared to give up the warranty and likely 
end up with a dead vehicle as well. The gateway mentioned above can be 
set up to put the engine and transmission into limp mode if it detects 
tampering with the PCM programming.
