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.
- 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 e37 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.

Description
Check mode has a higher sensitivity to malfunctions
and can detect malfunctions that normal mode
cannot detect. Check mode can also detect all the
malfunctions that normal mode can detect. In check
mode, dtcs are detected with 1 trip detection logic.

Torque converter clutch solenoid performance (shift solenoid valve dsl)
Description
The ecm uses the signals from the throttle position sensor, air-flow meter,
turbine (input) speed sensor,
intermediate (counter) shaft speed sensor and crankshaft position sensor to
monitor the engagement
condition of the lock-up clutch.
Then the ecm compares the engagement ...
