Opening and closing RF roof with a key fob

You can put the roof down while you approaching the car, how cool is this?

After successful implementation of the one-touch roof control module, next idea is to do this using a key fob from outside the car.

This is a very challenging task because the roof mechanism operates only when Ignition power is on. To solve this problem, I modified my ACC controller to control the IG relay instead. This module would listen to CAN messages and when activate IG relay when needed by pressing Lock or Unlock buttons on the key fob. After roof operation completed (which is also known as an event on the CAN bus) IG relay will be turned off. RF controller also can listen to CAN bus for key fob messages and activate mechanism when needed.

Quick implementation was successful, and I got everything working as desired. Because I already had Windows Controller installed, everything is fully functional. Technically windows controller could be optional, but if you leave windows down and then remotely put the roof up, there is no way to close windows without entering the car again. Also, in a US car after closing the roof, windows will leave a gap of 1″, which I can close remotely with one more click.

We tested it with RF 2017 and RF 2020, MT and AT versions.

This product will be available by end of June 2021 from our store.
