The fault is a direct consequence of modern automotive electronics. The car's UCH expects to "see" the original, paired modules. A key diagnostic step involves reading the UCH's live data, which will report the status of the "dongle" as either "not allocated," "allocated," or—in the case of the fault—"faulty". When a related module, such as the airbag control unit or the Electronic Power Steering (EPS), is changed, repaired, or cleared of crash data, it can break this digital handshake. The UCH perceives this mismatch and triggers the immobiliser as a security precaution, resulting in the dreaded no-start condition.

To fix the issue permanently, you need to understand the mechanics behind it. Owners should log into the official Renault portal
