Toyota RAV4 (XA40) 2013-2018 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.

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 ...

Exhaust gas precautions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases contain harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caus ...
Intermediate shaft speed sensor "A"
Description
This sensor detects the rotation speed of the counter gear. By comparing the
counter gear speed signal
(nc) with the direct clutch speed sensor signal (nt), the ecm detects the shift
timing of the gears and
approximately controls the engine torque and hydraulic pressure accord ...
