SECURITY LIGHT CONSTRUCTION/OPERATION [KEYLESS ENTRY SYSTEM]
id0914b3521100
Construction
• Allows visual verification of immobilizer system operation.
• If any malfunction is detected in the immobilizer system, the malfunction location can be verified by the security light flashing pattern.
-
Caution
-
• Use the Mazda Modular Diagnostic System (M-MDS) 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.
Operation
• When the immobilizer system is operating, the security light flashes
repeatedly 0.1 s every approx. 2 s.
• When the immobilizer system is deactivated normally, the security light illuminates for
approx. 3 s when the ignition switch is turned to the ON position.
• If the immobilizer system is not deactivated normally (malfunction detected by the on-board diagnostic function), the security light indicates a DTC. If this occurs, the security light flashes or illuminates for 1 min when the ignition switch is turned to the ON position, and then indicates the DTC.
-
― DTC 16 or under: Flashes
― DTC 21 or higher: Illuminated
-
Note
-
• The security light indicates the DTC 10 times.
• If multiple DTCs that can be verified with the security light are detected, only the DTC with the lowest number of those detected will be indicated by the security light.
