vehicle at least 30 minutes to reach an adequate battery state of charge to prevent an
ECU Update failure. Cycle the ignition OFF/ON before retrying ECU update again.

i Information
GDS ECU Updates must be performed in Auto Mode.
• If ECU Update starts but then fails in Auto Mode, perform update in Manual Mode to
recover.
• Turn off ignition for 30 seconds and try Manual Mode recovery.
• If unsuccessful, re-attempt Manual Mode after disconnecting the cables from the 12V
battery terminals and performing cap discharge (connecting bar or heavy wire
between “+” to “-“ cables).
