COMPRESSOR BYPASS SOLENOID VALVE INSPECTION [SKYACTIV-D 2.2]
id0113z7265500
Resistance inspection
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)
2. Remove the compressor bypass solenoid valve. (See COMPRESSOR BYPASS SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
3. Measure the resistance between the compressor bypass solenoid valve terminals A and B.

Airflow Inspection
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)
2. Remove the compressor bypass solenoid valve. (See COMPRESSOR BYPASS SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
3. Inspect airflow between the ports under the following conditions.

PID/DATA Monitor Inspection
1. Connect the M-MDS to the DLC-2.
2. Start the engine and warm it up completely.
3. Using the M-MDS, display the simulation item COMP_BPV. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].)
4. Verify that the PID COMP_BPV value goes from Off to On when the engine is raced at an engine speed of 3,500 rpm.
