Solve Launch X431 IMMO Elite Error "device SN not found" and "no data for current function"

Problem:

I tried to check vehicle remote function on the Launch X431 IMMO Elite, it said no data for current function. Then it brings another interface asking to update firmware but failed me again, immo elite gave another error device SN not found. Any solution?

Solution:

To use the function you must connect with Launch X431 key programmer add-on module.
