Toyota RAV4 Service Manual: Terminals of ecu (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.
Hint:
*: For 2gr-fe
- Using an oscilloscope, check waveform 1.
Can communication signal 
Hint:
The waveform varies depending on the can communication signal.
- Using an oscilloscope, check waveform 2.
Can communication signal 
Hint:
The waveform varies depending on the can communication signal.
- Using an oscilloscope, check waveform 3.
A/c compressor* operation signal
Hint:
*: Compressor and pulley for 2az-fe, compressor and magnetic clutch for 2gr-fe
- Using an oscilloscope, check waveform 4.
Compressor lock sensor signal* 
Hint:
*: For 2gr-fe

Monitor description
The air-fuel ratio (a/f) sensor varies its output voltage in proportion to
the air-fuel ratio. If the a/f sensor
impedance (alternating current resistance) or output voltage deviates greatly
from the standard range ...
Problem symptoms table (2006/01- )
Hint:
Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms are
listed in order of probability in the "suspected area" column
of the table. Check each symptom by checking the suspected
areas in the order they are listed. Replace p ...
