Don’t be scared we fixed the all

U1733-87-lost communication with CTM *

U1733-86 implausible data received from CTM – Convergence Telematics Module -Inter alia Bluetooth module, called Blue&Me in Fiat Chrysler group.

U1200-00-lost communication with power inverter module.

U1488-00 implausible data received from Electric Vehicle Control Unit.

U1705-86 implausible data received from radio (rrm).

U1726-86 implausible data received from ORC – Occupant Restraint Controller.

* The first symptom of CTM problems: flashing car mileage.
A possible fix could be proxy alignment with only good quality OBDII diagnostic tool:
