INPUT/OUTPUT CHECK MODE OPERATION

E5U092255430N06

Operation procedure

• Refer to Mazda MX-5 Workshop Manual.

Input circuit check

• When the parts listed in the chart are operated and a signal is output to the instrument cluster, the built-in

microcomputer determines the operability of the input circuit based on that signal.

Individual circuit check

• By operating the parts listed in the chart, the built-in microcomputer determines the operability of the individual

parts.

PID/Data Monitor and Record

• The PID/data monitoring items for the instrument cluster is as shown in following the table:

Monitor item table

—: Not applicable

Odometer-data Transfer

• If all the following conditions are met, the odometer data (total traveled distance) in the previous instrument

cluster is automatically transferred to a new instrument cluster during the configuration. If any of the conditions
are not met, odometer-data transfer cannot be performed.
Previous instrument cluster

— No malfunction (Configuration data can be read using the WDS or equivalent.)
New instrument cluster

— Odometer display is less than 100 km

— Odometer has no malfunction

Note

• If the odometer display of a new instrument cluster is 100 km or more, an error is displayed on the WDS

after the configuration is completed. In this case, the configuration data for items other than the odometer
are transferred to a new instrument cluster.
