Toyota RAV4 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

Inspection procedure

1. Read value of intelligent tester (reg ctrl currnt)

1. Connect the intelligent tester (with can vim) to the dlc3.
2. Turn the ignition switch on and turn the intelligent tester main switch on.
3. 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.

2. Inspect a/c compressor

1. Disconnect the a/c compressor clutch connector.
2. Measure the resistance of the connector.

Standard resistance

3. Check wire harness (a/c compressor - air conditioning amplifier)

1. Disconnect the b23 a/c compressor connector.
2. Disconnect the e37 amplifier connector.
3. Measure the resistance of the wire harness side connectors.
