The immobilizer system is a key part of a vehicle’s electronic protection, designed to prevent unauthorized engine start by verifying a coded transponder signal. In specific cases—such as ECU replacement, diagnostic testing, or performance tuning—technicians may need to disable this function. This procedure, known as immo off, allows the engine to start without communication from the immobilizer, ensuring the ECU can operate independently during service or bench testing.
This guide explains how to perform an immo off operation on Bosch EDC17C18 ECUs using the CK Decode software. The process is safe, repeatable, and designed for professionals who require accuracy and efficiency in ECU modification.
