2. Checking the Status

Checking The Status







- Engine idling.

The status of the fault can be determined by activating the quick test of the fuel tank system.

If the quick test detects a tank system fault, the fault is permanent.

If the quick test does not detect a tank system fault, the fault is intermittent.

Activate the quick test of the fuel tank system.

Read the battery voltage and status for the quick test tank system

Check the parameters according to the conditions for starting the quick test of the fuel tank system.

The following conditions must be met in order for the quick test of the fuel tank system to be run correctly.

NOTE: Conditions for starting the quick test of the fuel tank system

- The diagnostic trouble codes (DTC) for the engine temperature sensor, atmospheric pressure sensor, outdoor temperature sensor, EVAP valve or diagnostic trouble codes (DTC) for electrical faults on the leakage diagnostic module must not be stored when the quick test tank system is activated.
- Engine idling
- Battery voltage must be 11-15 V.
- The status of the quick test for the fuel tank system shall be Not running. The battery voltage must be correct throughout the entire test. The test can take up to 10 minutes, depending on the quantity of fuel in the fuel tank.
- Active the quick test for the fuel tank system by clicking the start button. Click the stop button to cancel the test.

Check that the quick test has started by reading off the status of the test phase. When status of the test phase goes to Reference, the test has started.

Wait until the test is complete. When the test has been completed, the status of the test phase shall be Not in progress and the status of the quick-test of the fuel tank system shall be Completed.

If the quick-test does not detect a fault, the test result for the leakage diagnosis unit and fuel tank system will be "No fault detected".

HINT: Even if some test result is Fault detected after completed test, the diagnostic trouble code (DTC) for the fault will not be stored in the Engine control module (ECM). Respective diagnostic trouble codes (DTC) will be stored in the engine control module (ECM) should the same result be obtained after a regular leakage scan, that is to say running on.

Select an alternative to continue when test is completed

1. The test result for the fuel tank system and the leakage diagnosis unit is "No fault detected".
2. The test result for the fuel tank system is "Fault detected, minor leak" or "Fault detected, major leak".
3. The leakage diagnosis is interrupted, the test result for the leakage diagnosis unit is Fault detected.
4. The leakage diagnosis is interrupted, status for the leakage diagnosis is Blocked.
