Compressor solenoid circuit (2005/11-2006/01)

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.

1. 1
   Read value of intelligent tester (reg ctrl currnt)
2. 2
   Connect the intelligent tester (with can vim) to the dlc3.
3. 3
   Turn the ignition switch on and turn the intelligent tester main switch on.
4. 4
   Select the items below in the data list, and read the value displayed on the intelligent tester.

   

2. Inspect compressor and pulley

1. 1
   Disconnect the compressor and pulley.
2. 2
   Measure the resistance of the connector.

Standard resistance

3. Check wire harness (compressor and pulley - air conditioning amplifier)

1. 1
   Disconnect the b23 compressor and pulley connector.
2. 2
   Disconnect the e37 amplifier connector.
3. 3
   Measure the resistance of the wire harness side connectors.
