This is a somewhat unique OBD method. Indeed, the secure gateway present on some vehicles requires the ATPG050 cable to be connected to a connector located in the engine compartment. Therefore, the operation turns out to be significantly more complex than a standard operation via the OBD-II diagnostic socket. However, rest assured, we have put everything in place in the AutoTuner software instructions to help you locate the connector and proceed with the various operations without any risk.

The concerned ECUs are mostly equipped with a "secure gateway" that prevents writing via the OBD-II diagnostic socket. In this case, it is necessary to use the ATPG050 cable to write to the ECU.

It is an authentication system set up by the manufacturer to interact with the vehicle through the OBD-II diagnostic socket.

Once the OBD cable is plugged in, during identification, the AutoTuner software immediately indicates if the vehicle is equipped with a "secure gateway".

You will receive an error message because the SGW (secure gateway) forbids entering programming mode without prior authentication.

A detailed procedure is available in the AutoTuner software instructions when you select a concerned ECU.

Fortunately not, our recovery solution will allow you to write the calibration again. You just need to follow the instructions to maintain contact during writing to avoid this problem in the future.

Data logging as well as fault deletion (DTC) can be performed via the OBDII diagnostic socket using the usual OBD cable (ATOBD001).

Given the significant number of vehicles targeted by this new feature, unfortunately, we did not have the opportunity to test our solution on all vehicles equipped with a secure gateway, especially for Nissan and Mitsubishi manufacturers. Therefore, we are calling on our community to help us refine and improve the proposed solution.
