ON-BOAD DIAGNOSTIC PID DATE MONITOR FUNCTION

On-board Diagnostic Function

Malfunction detection function

• Detects overall malfunctions in the power retractable hardtop-related parts.

Memory function

• Stores malfunctions in the power retractable hardtop-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 power retractable hardtop control module and reading them out in real-time.

• Use the mazda modular diagnostic system (M-MDS) to read the PID/data monitor.
