Powertrain Control Module/Programming Off Board: Notes

NOTE: DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customer's concern.
NOTE: Off-Board Programming is used in situations where a control module must be programmed without having vehicle present. Off-Board Programming Adapter must be used to perform Off-Board Programming procedure. Adapter allows control module to power up and allows Tech 2(R) to communicate with control module.
NOTE: DO NOT disturb tool harnesses while programming. If an interruption occurs during programming procedure, programming failure or control module damage may occur.
