Open the hood, install a battery charger and verify that the charging rate provides approximately 13.5 volts.
2.
Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
3.

NOTE:
The StarSCAN should display a part number from a list of the following old ATC module software part numbers: 55111010AA to 55111010AH, or
551110011AA to 551110011AH. The display of one of these old part numbers by the ATC module will allow the StarSCAN(R) to update the ATC
module software with new software per this bulletin. Once the ATC module software has been updated per this bulletin, the ATC module may or may
not allow the StarSCAN® to display a proper ten digit part number (either the original pin or otherwise). This condition may not allow future
reprogramming of the ATC module, if that were required at a later date.
