Default Re: I hacked the Skreem, the Skreemulator

The BCM is responsible for controlling the central locking pump in the trunk via CAN (unfortunately not the same CAN as the skreem to the PCM).
There is a connector in the passenger footwell behind the cover where the amplifier or the transmission control unit is located where this serial cable can be easily tapped.
This plug is also a potential source of error if the Crossfire can't be opened with the remote control (I already had a Crossfire with this problem).
You wouldn't even need to decode these signals, just record them (1x for open and 1x for close) and you can try reproduce them with an Arduino.
I would have no idea how to do that with the Arduino. But it works, the SPI and I2C protocol shows what the Arduino can do that.
In the picture the arrow points to the connector, is a connector with if I remember correctly only one cable.
So we are in it! Thank you.
I'll try it out this weekend and share the results.

By the way, what do you mean with source of error?, I'm asking because of my remote got broken and I use the key to open and close the car, would it be a problem with the tests?
