HINT
If the result is not as specified, the combination meter assembly may be malfunctioning.

(1) Waveform 1: Using an oscilloscope









(2) Waveform 2: Using an oscilloscope





HINT
As the vehicle speed increases, the cycle of the signal waveform narrows.





2. ACCESSORY METER ASSEMBLY





(a) Disconnect the F1 accessory meter assembly connector.

(b) Measure the voltage and resistance of the wire harness side connector.





HINT
If the result is not as specified, the accessory meter assembly may be malfunctioning.

(1) Waveform 1: Using an oscilloscope









(2) Waveform 2: Using an oscilloscope









3. MAIN BODY ECU





(a) Disconnect the E7, E8 and 1A main body ECU connectors.

(b) Measure the voltage of the wire harness side connectors.
