Toyota RAV4 Service Manual: Compressor solenoid circuit (2005/11-2006/01)
Description
In this circuit, the compressor receives a refrigerant compression demand signal from the air conditioning amplifier. Based on this signal, the compressor changes the degree of refrigerant compression.
Wiring diagram
Inspection procedure
- Read value of intelligent tester (reg ctrl currnt)
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on and turn the intelligent tester main switch on.
- Select the items below in the data list, and read the value displayed on the intelligent tester.
Ok: the display is as specified in the normal condition column.
- Inspect compressor and pulley
- Disconnect the compressor and pulley connector.
- Measure the resistance of the connector.
Standard resistance 
- Check wire harness (compressor and pulley - air conditioning amplifier)
- Disconnect the b23 compressor and pulley connector.
- Disconnect the e36 amplifier connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Check wire harness (compressor and pulley - body ground)
- Disconnect the b23 compressor and pulley connector.
- Measure the resistance of the wire harness side connector.

Replace air conditioning amplifier
Pressure sensor circuit
Description
This dtc is output when the refrigerant pressure is either extremely low
(0.19 Mpa [2.0 Kgf/cm2, 28 psi]
or less) or extremely high (3.14 Mpa [32.0 Kgf/cm2, 455 psi] or more). The ...

Check mode procedure
Description
Check mode has a higher sensitivity to malfunctions
and can detect malfunctions that normal mode
cannot detect. Check mode can also detect all the
malfunctions that normal mode can detect. In check
mode, dtcs are detected with 1 trip detection logic.

Memory recall function (vehicles with a smart key system)
Each electronic key can be registered to recall your preferred driving
position.
Registering procedure
Record your driving position to button “1” or “2” before performing
the following:
carry only the key you want to register, and then close the driver’s
door.
If 2 or more keys ar ...
Random / multiple cylinder misfire detected
Description
When the engine misfires, high concentrations of hydrocarbons (hc) enter the
exhaust gas. Extremely
high hc concentration levels can cause increases in exhaust emission levels.
High concentrations of hc
can also cause increases in the three-way catalytic converter (twc) te ...
