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.
