Acadia FWD V6-3.6L (2007)
voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use an additional jump battery if
necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Be sure to turn off
or disable 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 observed.
The ignition switch must be in the proper position. The Tech 2(R) 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 communication 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 occur.
DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are
secure and the TIS terminal operating software is up to date.
