The latest version of
MES (
MultiECUscan) can now reset the tyre pressure monitoring system.
It is difficult to access parts diagrams, but
ePER does show the valve that sends the data, but I cannot find any separate control unit. My assumption would be that it was programmed into the main body computer.
Your pic is not clear. We can see it is a small electronic box, but we cannot see any identification on it. If it bears a part number,
ePER will find it, and show its approximate location. However, you have one to photograph. Or have you just found a pic online? If you have one, where did you get it from? If from your car, then you know where it was.
Why do you think you need one? Start at the beginning, rather than after a diagnosis and decision.
With more info, we may be able to help.
