Also, the latch on the K11 box is open. ( I don't know what the K11 does. ) The right side should press in and pull the connector in. I'm surprised it even makes contact.
I'll look and check the latch on the K11 module, but I didn't touch it when I removed the panel from the footwell.
If I remember the K11 is the ESP (electronic stability program) module. No error codes detected or warning light for ESP.
