If the Automatic ECU Upgrade process fails, cycle the ignition key to OFF for at least 30 seconds
to reset the control unit. Then resume programming using the Manual ECU Upgrade processes.
After the ECU Upgrade process shows 100% complete, cycle the ignition key again to OFF for at
least 30 seconds to reset the control unit. This step is important for establishing normal
powertrain communication and to prevent system errors.
