OBDSTAR X300 Classic G3 Key Programmer has the ability to unlock ECU function for Alfa Romeo, Fiat, Chrysler, Dodge, Jeep and others.

Background:

Nowadays, in order to meet the various needs, there are various ECU modules on the car. These modules control almost every aspect of the vehicle. They communicate through the bus. These modules contain vehicle-specific info, usually the VIN code, but not all modules are VIN code. If the ECU module is damaged, we replace it with a new one. We have to use a dealer tool to program the ECU module through the bus so that the other modules in the vehicle will accept it. If this is not done, the new module cannot work properly.

In daily maintenance, in order to save costs, we usually use second-hand modules, but the FCA official in order to let the maintenance technicians use the original brand new module, they add a recognition of the judgement function, once the scanning recognition of the current module exists, other vehicle VIN or other specific information, it will determine the current ECU module for the second-hand control module default for the lock state and will not be programmed. After using the ECU advanced function by OBDSTAR, it can solve the above problems and then can program the second-hand ECU module. This ECU unlock function can operate directly through the OBD diagnostic port on the car, and you can also operate by bench.
