LEAK DIAGNOSTIC UNIT PUMP
Graphic display in the fuel tank system quick test.
Measurement range 0-400 mA.
The engine control module (ECM) calculates the value from the pump in the leak diagnostic unit.
The value varies depending on the pressure in the fuel tank system. Higher pressure results in increased power consumption.
FUEL TANK SYSTEM QUICK TEST
In order for the quick test to start, the status of this parameter must be "Not completed".
- Completed = The engine control module (ECM) has completed the quick test / diagnostic of the fuel tank system during the present operating cycle
- Not completed = The engine control module (ECM) has not completed the quick test / diagnostic of the fuel tank system during the present operating cycle.
TEST PHASE
In order for the quick test to start, the status of this parameter must be "Not running".
The parameter indicates the phase of the test.
- Reference= Reference phase for leaks and function test of the leak diagnostic unit is running
- Fuel tank system = Diagnostics for major leak and minor leak running
- Not running = No quick test or diagnostic is running.

Shows the current status of the quick test (In progress/Not in progress)
Shows the current phase of the leak diagnosis. For more information, see "Test phases, quick test tank system".
DMTL, TEST RESULT
Shows the test result on the leak diagnostic unit (DMTL).
If "Fault found" is shown, the Engine control module (ECM) has generated a diagnostic trouble code (DTC) for the fault. Fault tracing should be started/continued.
TANK SYSTEM, TEST RESULT
Shows the test result for the fuel tank system.
If "Minor leak found" or "Major leak found" is shown the Engine control module (ECM) has generated a diagnostic trouble code (DTC) for the fault. Fault tracing should be started/continued.
