But the problem is that the TCU don't recognize any phone when it was supposed to happen (right after turn the ignition on). When I first connected the TCU to the car, I knew she had to go into pairing mode, but that didn't happen. I only managed to pair a phone, when coded it .
And this is the real problem, because whenever I want to pair a phone, I have to code the TCU, and it's very boring, apart from that, it can only have a phone paired at a time.

Maybe I'm coding it the wrong way... I need ideas...
