Check Using NGS Scan Tool

1. Connect the SSTs (NGS tester) to DLC-2.
2. Connect a vacuum gauge to the pressure regulator vacuum hose.
3. Start the engine and completely warm up the engine.
4. Increase the engine speed and note the vacuum gauge reading.




5. Select the SIMULATION TEST function of the NGS.
6. Select the ABVVAC on the NGS display.
7. Use the SIMULATION TEST function, set the ABVVAC duty value at 100%. Increase the engine speed and note the vacuum gauge reading.
8. Verify that the value is lower than the one measured in Step 4.
- If not as specified, stop the engine.
9. Turn the ignition switch to ON.
10. Using the SIMULATION TEST function, inspect the operation sound of the ABV bypass solenoid valve (vacuum).
- If the operation sound is heard, inspect following.
- Vacuum hose for damage or looseness
- Vacuum pump
- Damaged diaphragm
- Shutter valve for being stuck
- PCM terminal voltage
2A (ABV solenoid valve: vent)
2M (ABV solenoid valve: vacuum)
- If the operation sound is not heard, inspect the ABV solenoid valve (vacuum).
