During device operation, a common warning may appear stating that the device does not obtain authorization for the A001 module when attempting ZF TC275/TC277/TC1782 TCU clone functions. This error is not caused by a connection failure or software bug. Instead, it clearly indicates that Yanhua Module 36 is missing.
After confirmation, the solution is straightforward: the device requires Yanhua Module 36 to unlock and authorize this specific function. Once Yanhua ACDP Module 36 is purchased and activated, the authorization can be refreshed, and the TCU cloning process will work normally.
