•  If a malfunction occurs in the system, a malfunction detection function is equipped to record the malfunction as a DTC. Recorded DTCs can be read by the Mazda Modular Diagnostic System (M-MDS).

•  The diagnostic system records the DTC while also storing the control status of the related instrument cluster as freeze frame data.

•  An input/output check function has been adopted that examines input signals to the instrument cluster and individual parts via the micro computer built into the instrument cluster.

•  A PID/data monitor function is equipped in the instrument cluster.

•  When configuring, the odometer (total traveled distance data) data from the previous instrument cluster can be transferred to the new instrument cluster.
