good morning

We are writing today to give technical advice for the cases in question that occur as a result of battery disconnection.

A customer called to request technical assistance and information regarding odometer flashing and Blue&me failure.

Anomaly convergence node and diagnosis tester does not talk  

In such cases, I suggest you disconnect the control unit connection  convergence node. Qhis operation is to be carried out as a test before replacing the convergence node control unit.

The reason is simple the convergence node starts working on its own again, just unplug the wiring and keep it unplugged for 2/3 hours

Then you install it on the machine and at the end of the test wait for it to start working on its own again.

Sometimes it takes a few minutes and sometimes a day before it works.

If it does not start working again after a few days, the convergence node control unit must be replaced with a new model.

In that case, the new ecu must be aligned with the car's network

greetings and good work to all Antonio
