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
