Note: Not all Accessport part numbers will be able to download unknown ROMs from another vehicle. Typically it needs to be in the same vehicle family in order for this process to work. If your vehicle is not compatible with the Accessport you will typically get a message stating "This Vehicle Is Not Supported."
With the Accessport hooked up to the vehicle select "Install"
After failing to recognize the vehicle, the Accesport will be set to "Unknown ROM" mode.
In "Unknown ROM" mode there will be a new option on the main menu called "User Tools" select that option.
Under "User Tools" select Save ECU Data. (Make sure the ignition is in the ON position but the car is not running in order for this to work properly)
In some cases the vehicle will not be supported by the firmware on the device and will display an error instead of saving a ROM.
After a successful Dump hook your Accessport up to your computer using Accessport Manager.
After connecting select the file and click "Save selected file to my computer"
If you're already in touch with our support team, email it to them within your support ticket. Otherwise proceed to the ROM Upload form so we can get support for your vehicle ASAP (See the Link Dump area for the submission form)
