When should I use the Synchronize Electronic Control unit data operation?

ANSWER:

This operation can be used to Sync the vehicle with Central Systems.  For example, if you have installed a component like a radio or cluster from a different vehicle, you may get a mismatch in the hardware and or the software.   Use the Sync operation to Sync the truck with Central Systems.   This will update Central Systems with the correct hardware and or software.   Note that if the installed component is not compatible with the vehicle you will get an error message.
