307 abs fault

Good day guys today, there was a problem called abs fault, I took it to the mechanic, he connected it to the PC, but he couldn't get into the brake section, he couldn't understand the problem. Thank you now

If it could not reach abs from pc, it is not using original peugeot software. or there may be a problem in the abs brain. I recommend connecting to a PC with original software.

One of the wheels, there is a short plug of this abs, the man I bought died, he said, check it, he won't break the brain easily.

remove the bonnet on the left front wheel, when the brain is viewed from the front, it stays on the right socket
