GDS AUTO MODE ECM UPDATE PROCEDURE:
1. Turn the vehicle's ignition key to the ON position.
2. Select ECU Upgrade on the initial GDS home page screen. If you are not at the home page double click GDS at top left of the screen to go back to
home page.
3. GDS will automatically determine the vehicle information based on the VIN it reads from the vehicle's ECM, then select Engine Control as system
and OK.
4. Select Auto Mode then ENGINE then OK so the ROM ID will be read:
5. After reading the ROM ID if there is an available update it will display a screen like that shown below with the available updates for the vehicle.
Select the Upgrade
Event: "225.UD 1.8 P0106, P0605 DTC LOGIC IMPROVEMENT." or any later (higher) event number that shows in the GDS list.
NOTE:
This screen is an example only. The GDS will show your vehicle, its current ROM ID and latest ROM ID for update based on the event that you
select. Select the most recent available (highest) event number in the list, even if it describes a different issue as it will ensure the vehicle receives the
latest available updates.
NOTE:
An error message may appear if the ECM Update has already been completed or is not available for your vehicle.
6. After selecting the Upgrade button the vehicle battery voltage is checked to make sure it is at least 12 volts, which is required to ensure reliable
update results. Select OK if the results indicate voltage is above 12 volts.
CAUTION:
If voltage is below 12 volts, then select Cancel and run the engine at idle for at least 10 minutes to ensure an adequate battery charge state for reliable
update results.
7. Updating will occur until 100% is reached on the bar graph, then the confirmation screen will be displayed. Turn the ignition key OFF for 10 seconds
then place it back in the ON position followed by select OK.
NOTE:
For push button start, push the button 2 times without depressing the brake pedal to get ignition on, as the first press is only accessories mode.
