I'm not seeing why you needed to add the lines to case 1 and case 2. The pins get written high in the default case before switching to case 1 or 2. Without the default case writing the pin high, the case 1 or case 2 won't be run until the second time around the loop, 50ms later since the default case is what sets the openMode to 1 or 2.

I was just trying a few things. I am very new to programming these things, so it is highly likely unneeded code. Without the added lines it did not run in auto mode at all. The output was high only as long as the switch was closed. A short push did not enable auto mode.

In any case, I'll wait for you to test, especially with the e brake support

Thanks
