The P1611 fault code refers to a Key ID Discord between the Immobilizer (IMM) and the Engine Control Module (ECM).

This code indicates a communication problem between the key and the vehicle’s ECM, which is responsible for controlling the engine’s functions. The Immobilizer is an electronic device that prevents the engine from running unless the correct key is present. It works by activating a microcircuit inside the key, which broadcasts a unique binary code. The ECM reads this code and determines if the key is current and valid.

If everything is in order, the ECM activates the fuel-injection sequence. In the case of a P1611 fault code, there is a mismatch or discord between the key’s ID and the ECM’s ID. This can be caused by a faulty key, a problem with the Immobilizer system, or a communication issue between the key, the Immobilizer, and the ECM. To resolve this issue, it is recommended to have the vehicle diagnosed by a qualified technician who can identify the specific cause and perform the necessary repairs.

What are the possible causes for the automobile fault code p1611, which triggers the engine light or service engine soon warning light?
