Service Procedure

Before reprogramming, check battery charge to prevent a reprogram error of the PCM/ECM. Battery voltage must maintain between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use an appropriate charging method. Be sure to turn off or disconnect any system that may put a load on the battery such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not followed.

The ignition switch must be in the proper position. The Tech 2 prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.

Make certain all tool connections are secure, including the following components and circuits:

^ The RS-232 communications cable port

^ The connection at the data link connector (DLC)

^ The voltage supply circuits

DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may result. DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful.
