Copy and Restore

WARNING: This page is about a different car, the 2021 GMC Sierra 3500 HD and 2021 GMC Sierra 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Copy:

When replacing the Power Take-Off module (PTOM) prior to disconnecting any electrical connections it is recommended that the Copy portion of the PTOM Copy and Restore procedure is run using the GDS2 Scan Tool. This application is available under Module Diagnostics>(K44) Power Take-Off Module>Configuration/Reset Functions>PTO Operation Mode>Copy and Restore. Follow the steps for copying the PTO settings. Once the Copy function is complete the PTOM can now be disconnected and replaced.

Restore:

Once the PTOM has been replaced and all electrical connections have been made, the Restore portion of the procedure can be performed. This portion restores any settings that may have been set in the removed PTO module and may have been unique for the vehicle's usage and/or application.

Note:

If communications by GDS2 with the to be replaced PTO module cannot be established, the settings, beyond the factory defaults, will need to be reconfigured to the customers requirements for proper PTO operation. This may be accomplished as noted in the Module Setup section below.
