Pinout Values and Diagnostic Parameters
TERMINALS OF ECUTerminals Terminals Of Control Module/Pinouts - Check Combination Meter Assembly:
1. CHECK COMBINATION METER ASSEMBLY
a. Disconnect the C6 meter connector.
b. Measure the resistance and voltage 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 C6 meter connector.
Part 1:
Part 2:
Part 3:
d. Measure the voltage of the connector
If the result is not as specified, the combination meter may be malfunctioning.
e. Using an oscilloscope, check the signal waveform of the meter.
Oscilloscope Waveform:
Waveform 1 (Reference)
HINT: As vehicle speed increases, the wavelength shortens.
Oscilloscope Waveform:
Waveform 2 (Reference)
HINT: As vehicle speed increases, the wavelength shortens.
