Pinout Values and Diagnostic Parameters
TERMINALS OF ECUTerminals Of Control Module/Pinouts - Check Air Conditioning Amplifier Assembly:
1. CHECK AIR CONDITIONING AMPLIFIER ASSEMBLY
Part 1:
Part 2:
a. Measure the voltage and resistance of the wire harness side connector.
If the result is not as specified, the A/C amplifier may have a malfunction.
Oscilloscope Waveform:
1. Waveform 1 (Reference)
Oscilloscope Waveform:
2. Waveform 2 (Reference)
HINT: The waveform varies depending on the CAN communication signal.
Oscilloscope Waveform:
3. Waveform 3 (Reference)
HINT: The waveform varies depending on the CAN communication signal.
Terminals Of Control Module/Pinouts - Check ECM:
2. CHECK ECM
a. Measure the voltage of the connectors.
If the result is not as specified, the ECM may have a malfunction.
Oscilloscope Waveform:
1. Waveform 1 (Reference)
HINT: The waveform varies depending on the CAN communication signal.
Oscilloscope Waveform:
2. Waveform 2 (Reference)
HINT: The waveform varies depending on the CAN communication signal.
