ON-BOARD DIAGNOSTIC SYSTEM [REAR BODY CONTROL MODULE (RBCM)]

• The on-board diagnostic function consists of the following functions: A malfunction detection function, which detects overall malfunctions in the rear body control module (RBCM)-related parts; a memory function, which stores detected DTCs; a display function, which indicates malfunction locations and status via DTC output; and a PID/data monitoring function, which reads out specific input/output signals and verifies the input/output condition.

• Using the Mazda Modular Diagnostic System (M-MDS), DTCs can be read out and deleted, and the PID/data monitoring function can be activated.

• Detects malfunctions in input/output signals.

• If a malfunction occurs, the rear body control module (RBCM) records the malfunction as a DTC. A recorded DTC can be read by the Mazda Modular Diagnostic System (M-MDS).
