ON-BOARD DIAGNOSIS SYSTEM PID DATA/MONITOR FUNCTION OPERATION (KEYLESS ENTRY SYSTEM) [ADVANCED KEYLESS SYSTEM]

id0914b1103100


On-board Diagnostic Function


Malfunction detection function

•  Detects overall malfunctions in the keyless entry system-related parts.


Display function

•  If any malfunction is detected, the keyless warning light (red) in the instrument cluster illuminates to inform the driver of a system malfunction.


Memory function

•  Stores malfunctions in the keyless entry system-related parts detected by the malfunction detection function, and the stored malfunction contents are not cleared even if the ignition switch is turned to the LOCK position or the negative battery cable is disconnected.

PID/data monitor function

•  The PID/data monitor function is used for optionally selecting input/output signal monitor items preset in the keyless control module and reading them out in real-time.
•  Use the mazda modular diagnostic system (M-MDS) to read the PID/data monitor.
