2. Verify that the vacuum increases to –80 kPa {–600 mmHg, –24 inHg} or more.
Operation Inspection
1. Connect a vacuum pump to the VBC solenoid valve port A, and apply vacuum.
2. Switch the ignition to on.
3. Simulate the VBCV PID to 100% using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR-CD 2.2].)
4. Verify that the vacuum is decreased.
Resistance Inspection
1. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)
2. Disconnect the VBC solenoid valve connector.
3. Measure the resistance between the VBC solenoid valve terminals.
