TERMINALS OF ECU

1. CHECK COMBINATION METER ASSEMBLY





(a) Disconnect the C8 meter connector.
(b) Measure the voltage and resistance of the wire harness side connector.





If the result is not as specified, there may be a malfunction on the wire harness side.
(c) Reconnect the C8 meter connector.
(d) Measure the voltage and resistance of the connectors.






(e) Using an oscilloscope, check the signal waveform of the meter.





Waveform 1 (Reference)





HINT: As engine speed increases, the wavelength shortens.





Waveform 2 (Reference)





HINT: As engine speed increases, the wavelength shortens.
