the charging voltage to climb above 13.5 volts during the flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
WARNING!
The vehicle must not be connected to a high voltage charger when performing software updates.

open turn the ignition on then off. Once successful a note will appear on the wiTECH screen indicating the
contactors are open.**
3. Remove the 30 Amp fuse for the Brake Booster Vacuum Pump from the Power Distribution Center (PDC)
located in the engine compartment.
