Mitsubishi B1766 Verified Direct

Understanding how to diagnose and resolve this fault code is critical for lock smiths, automotive technicians, and DIY mechanics working on modern Mitsubishi platforms like the Pajero Sport, Outlander, L200, and Montero Sport. Anatomy of Code B1766: Why it Triggers

In short: The “verified” part simply means the code has been confirmed as active or historic by your scan tool.

In automotive repair, a "verified" DTC is more than just a code read by a scanner; it means a technician has performed a systematic diagnostic process to confirm the root cause.

"Transponder registered for another vehicle" or "Already learned by another vehicle".
