I have very little experience in automotive electronics and need some help. I am building a 1953 4x4 truck using a 2008 4x4 sport trac chasis, drivetrain, and electronics. I want to turn off the TPMS, Door Ajar, Seat Belt warnings, etc. I have downloaded the Forscan software but have searched everywhere I can on the internet for which codes to modify and cannot find what I need. Can anyone on the forum help with this?
That is not something you will be able to do with a scan tool.
You'll either have to carry over all of the components to all of those systems and have them working properly, or cover up the warning lamps.
Or use a custom gauge cluster and/or stand alone engine control module.
