Set-up for Module Programming/Reprogramming

Important:  Ensure that the vehicle battery is fully charged and that a battery charger is no longer connected. If performing this procedure for module replacement, install new module before proceeding. Before reprogramming close the doors and wait two minutes to allow other modules to stop communicating via the class 2 data line. Failure to do so could result in a failed reprogramming procedure.

• Turn OFF all accessories.
• Turn ON the ignition, with the engine OFF.
