INPUT/OUTPUT CHECK MODE OPERATION

BHE092255430T06

## Operation procedure

• Refer to RX-8 Workshop Manual.

## Input circuit check

• When the parts listed in the chart are operated and output a signal to the instrument cluster, the built in microcomputer judges the quality of the input circuit based on that signal.
