Checking the status
- The status of the fault can be determined by activating a quick test of the fuel tank system
- The fault is permanent if a fault is detected in the leak diagnostic unit when running the quick test of the fuel tank system
- The fault is intermittent if no fault is detected in the leak diagnostic unit when running the quick test of the fuel tank system
- Switch off the ignition to ensure that the status of the quick test for the fuel tank system is "NOT COMPLETED". The test cannot be started if the status is "COMPLETED"
- Ignition on
- Activate the quick test of the fuel tank system
- Read off the battery voltage, the status of the quick test of the fuel tank system and the status of the test phase. Check the parameters according to the conditions for starting the quick test of the fuel tank system.NOTE:
The following conditions must be met in order for the quick test of the fuel tank system to be run correctly.
Conditions for starting the quick test of the fuel tank system
- Diagnostic trouble codes (DTC) ECM-4000, ECM-4007, ECM-4010, or ECM-4024 are not stored
- Engine off, ignition on
- The battery voltage must be 11-14 V
- The status of the test phase must be "NOT RUNNING".
- The status of the quick test for the fuel tank system must be "NOT COMPLETED".
NOTE: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. Connect a battery charger if necessary.
- 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. The test has started when the status of the test phase is "REFERENCE 1".
Wait until the test is complete. When the test is completed, the status of the test phase must be "NOT RUNNING" and the status of the quick test for the fuel tank system must be "COMPLETED".
If no faults are detected after the quick test of the fuel tank system, the test result for the leak diagnostic module and the fuel tank system will be "NO FAULT FOUND".
If a fault is detected after the quick test of the fuel tank system is complete, the test result for the fuel tank system or leak diagnostic unit will be "FAULT FOUND" with the fault type, depending on the fault.
HINT: If the test result is "FAULT FOUND" and the fault type is displayed after the completed test, a diagnostic trouble code (DTC) for the fault will be stored in the control module.
