ABS brake failure

Good afternoon.

I have Peugeot 307 2006, I have a problem of ABS failure, it led it to 160km for throwing races, suddenly stops and ABS is activated.

Who has solved this problem, the sensors are fine, the wheel that detects the sensor too, they tell me that possibly a distributor module but they have doubt because nothing appears in the Sccaner .. Alhguien has solved it. I am already 6 months old, I use it carefully. But I want to fix it. greetings..

A good scanner should throw the fault if they are the speed sensors that it carries on each wheel or if it reaches the module as they can also see many more parameters.

Have the lines to the ABS computer check?
