Toyota RAV4 (XA40) 2013-2018 Service Manual: Terminals of ecu (2005/11-2006/01)
- Check air conditioning amplifier
- Measure the voltage and resistance of the connectors.
Hint:
Check from the rear of the connector while it is connected to the air conditioning amplifier.
- Using an oscilloscope, check waveform 1.
Compressor and pulley operation signal
- Using an oscilloscope, check waveform 2.
Blower motor control signal 
Hint:
When the blower level is increased, the duty ratio changes accordingly.
- Using an oscilloscope, check waveform 3.
Can communication signal 
Hint:
The waveform varies depending on the can communication signal.
- Using an oscilloscope, check waveform 4.
Can communication signal 
Hint:
The waveform varies depending on the can communication signal.
- Check air conditioning control
- Measure the voltage and resistance of the connectors.
