ON-BOARD DIAGNOSIS SYSTEM FUNCTION [KEYLESS ENTRY SYSTEM]

id0914b3533300


DTC table

•  The immobilizer system is provided with an on-board diagnostic function.
•  On-board 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 indicates a DTC. DTCs are simultaneously saved in the instrument cluster and PCM. The number of saved DTCs can be verified using the Mazda Modular Diagnostic System (M-MDS).
Caution
•  Always use the Mazda Modular Diagnostic System (M-MDS) or equivalent to verify DTCs even if the security light indicates a DTC. If the security light itself has a malfunction, it is possible that a DTC may not be indicated properly. In addition, there are DTCs which cannot be verified using the security light, and can only be verified using the Mazda Modular Diagnostic System (M-MDS).
•  DTCs for the immobilizer system that are stored in the instrument cluster and PCM are cleared when the ignition switch is turned from the ON to the LOCK (ACC) position.
Note
•  If two or more malfunctions are detected as a result of on-board diagnosis, only the DTC with the lowest number of those detected will be indicated by the security light. The PCM and instrument cluster store multiple DTCs at the same time.
•  If two or more immobilizer system DTCs are detected, first repair the part for the DTC indicated by the security light. After repairing one location, turn the ignition switch from the LOCK to the ON position and perform the immobilizer system on-board diagnostic function.
Note
•  In the approx. 1 min after detecting a malfunction and before indicating the DTC, the security light illuminates or flashes in the following patterns:
