Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Copy and Restore
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.
