WARNING GDS Vehicle Battery Voltage: • This ICCU Update is long, so the 12V battery must be at good charge level (>60% SOC). Attach a Battery Charger to maintain the 12V battery if the vehicle had the DTC P1A9096 incident, as it would be more likely that the 12V Battery will be low. • If the voltage is below 12 volts as per the GDS warning, then select Back and run the 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 the 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).
