Terminals of ecu (2006/01- )

1. Check air conditioning amplifier

1. Measure the voltage and resistance of the connectors.

Check from the rear of the connector while it is connected to the air conditioning amplifier.

*: For 2gr-fe

2. Using an oscilloscope, check waveform 1.

A/c compressor* operation signal

*: Compressor and pulley for 2az-fe, compressor and magnetic clutch for 2gr-fe.

3. Using an oscilloscope, check waveform 2.

Blower motor control signal

When the blower level is increased, the duty ratio changes accordingly.

4. Using an oscilloscope, check waveform 3.

Can communication signal

The waveform varies depending on the can communication signal.

5. Using an oscilloscope, check waveform 4.

Can communication signal

The waveform varies depending on the can communication signal.

6. Using an oscilloscope, check waveform 5.

Compressor lock sensor signal*

*: For 2gr-fe

2. Check air conditioning control

1. Measure the voltage and resistance of the connectors.
