The need for a stable voltage environment is essential to ensure a successful reprogramming event. Every OEM tool has a recommended target system voltage in which the event should take place. They vary from make to make, and sometimes from model to model within one manufacturer.
Here are the updated OEM-specified voltage environments for module reprogramming, developed and updated in partnership with Clore Automotive's colleague Tanner Brandt, diagnostic technician, technical trainer, and founder of Auto Diag Clinic.
