What are the guidelines and requirements for reprogramming the Engine Control Module on 2002 Toyota Sequoia?

Starting in 2001, Toyota/Scion and Lexus vehicles feature flash reprogrammable Powertrain Control Modules (PCM). Reprogramming should follow Technical Service Bulletins. Use validated tools like the Toyota/Lexus scantool or J2534 interfaces. The process requires specific software and equipment, and must be uninterrupted to avoid damaging the vehicle controller.
