Immo off Marelli IAW4AF for Fiat models
The Marelli IAW 4AF ECU is widely used across Fiat models from the late 1990s through the mid-2000s. Commonly found in vehicles such as the Fiat Seicento, Palio, Panda, and Fiorino, these ECUs are known for immobilizer faults that lead to starting issues. Our immo off solution for the IAW 4AF disables the immobilizer system within the ECU’s internal memory, allowing the vehicle to start without coded keys or transponder systems. This solution is ideal for vehicles with lost keys, faulty code boxes, or immobilizer failures.

Marelli IAW4AF Immo off with CK Decode
CK Decode is a popular immobilizer deletion tool used for various ECUs, including the Marelli IAW4AF.
To use CK Decode, users extract the necessary files from the IAW4AF ECU (often via EEPROM programming tools) and upload them to the software for processing. Afterward, the adjusted file is flashed back onto the ECU, effectively bypassing the immobilizer system.
