Toyota RAV4 (XA40) 2013-2018 Service Manual: Compressor solenoid circuit (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.
Hint:
*: Compressor and pulley for 2az-fe, compressor and magnetic clutch for 2gr-fe
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 a/c compressor
- Disconnect the a/c compressor connector.
- Measure the resistance of the connector.
Standard resistance
- Check wire harness (a/c compressor - air conditioning amplifier)
- Disconnect the b23 a/c compressor connector.
- Disconnect the e36 amplifier connector.
- Measure the resistance of the wire harness side connectors.

Knock sensor 1 circuit
Description
Flat type knock sensors (non-resonant type) have structures that can detect
vibrations over a wide band
of frequencies: between approximately 6 khz and 15 khz.
A knock sensor is fitted onto the engine block to detect engine knocking.
The knock sensor contains a piezoelectri ...
