•  The immobilizer system is provided with a malfunction diagnosis function.

•  Malfunction diagnosis of the immobilizer system occurs automatically when the ignition switch is turned from the LOCK (ACC) to the ON (START) position.

•  If the results of the malfunction diagnosis show a malfunction in the immobilizer system, the security light displays a DTC. At the same time, DTCs are stored in the PCM and instrument cluster. The stored DTCs can be verified using the Mazda Modular Diagnostic System (M-MDS).
