Disconnect and connect the related connectors several
times to check.
C. Always connect any disconnected connectors before going on to
the next step.

If the power is turned ON with the connectors still
disconnected, unnecessary abnormality displays will be
generated.
D. When performing troubleshooting of circuits (measuring the voltage, resistance, continuity, or current), move the
related wiring and connectors several times and check that there is no change in the reading of the tester.

If there is any change, there is probably a defective contact in that circuit.
