Hello, I'm trying to read a 2018 Ford Ranger 2.2 Diesel engine, but the VCM Editor informs the following message before reading: "Your controller requires a software update in order to enable tuning. Would you like to generate the update file? This is a non-volatile process and no data will be written to your vehicle until you write the patch back with VCM Editor."
My question: is it a simple and safe process to perform this update? Thank you all
