Sure, Autel MAxiSys tools do have the ability to write VIN. Specific function availability will vary by year and model.
Here is an example of the VIN writing options for a 2006 Dodge Ram.
The “Check VIN” function works the same as other scan tools, if there is no VIN in the PCM it will then allow you to write the VIN number to the module.
