KESSv2: reading and writing FCA Magneti Marelli IAW 10GF through OBD.
Today’s update it’s about the ECU Magneti Marelli IAW 10GF equipped on some vehicles of the FCA Group more popular in particular in the South American market.

This update, real reading and writing through OBD. The 729 KESSv2 protocol, allows you to remap quickly and safely the Fiato Argo, Cronos, Mobi, Renegade, Toro, and Uno: petrol engine vehicles with 1.0, 1.3 and 1.8 motors.

The KESSv2 protocol complete the functionality of the 1473 K-TAG protocol: to read the microcontroller SPC564A70 in BAM mode, it is necessary the Freescale activation.

Since the end of 2017, the control of the access to the electronical system of the FCA vehicles is realized by using a specific module called “SGW” – Secure GateWay.

The SGW, physically placed in series between the OBD and the CAN ports of the vehicle, can intercept and filter any incoming and outgoing communications from the vehicle.

The correct functioning of the protocol is linked with the absence of the “SGW” module in the vehicle.
