Non-Enhanced EVAP System Diagnostic Procedure

1. Pinch off or plug the [1][2]EVAP vapor line to seal the EVAP system.

2. Connect the EEST red battery clip to the positive (+) battery terminal. Connect the black battery clip to chassis ground.

3. Install the appropriate fuel fill cap adapter to the fuel fill pipe. Refer to the Service Information for the appropriate fuel fill cap adapter part number.

4. Connect the EEST's nitrogen/smoke supply hose and vehicle fuel fill cap to the adapter.

5. Turn the nitrogen/smoke valve on the EEST control panel to SMOKE.

6. Use the remote switch to introduce smoke into the EVAP system for 60 seconds.

Important:
Additional smoke may need to be introduced at 15-second intervals until the leak source has been located.

7. Inspect the entire EVAP system for exiting smoke using the high intensity white light (J 41413-SPT).
