Test Results For The Fuel Tank System

The parameter indicates the result of the diagnostic for leakage in the fuel tank system. This diagnostic is run when during the MAJOR LEAK or MINOR LEAK test phases.

• NO FAULT FOUND = No leakage is detected by the control module
• FAULT FOUND, MINOR LEAK = Leakage of >0.5 mm detected by the control module. This fault status corresponds to diagnostic trouble code (DTC) ECM-400C, minor leak
• FAULT FOUND, MAJOR LEAK = Leakage of >1 mm is detected by the control module. This fault status corresponds to diagnostic trouble code (DTC) ECM-400C, major leak.
