• NO FAULT FOUND = No fault is detected by the engine control module (ECM)
• FAULT FOUND, HIGH SIGNAL = Fault in the leak diagnostic unit detected by the engine control module (ECM). This fault status corresponds to diagnostic trouble code (DTC) ECM-431D, Signal too high
• FAULT FOUND, LOW SIGNAL = Fault in the leak diagnostic unit detected by the engine control module (ECM). This fault status corresponds to diagnostic trouble code (DTC) ECM-431D, Signal too low
• FAULT FOUND, FAULTY SIGNAL = Fault in the leak diagnostic unit detected by the engine control module (ECM). This fault status corresponds to diagnostic trouble code (DTC) ECM-431D, Faulty signal
• FAULT FOUND, SIGNAL MISSING= Fault in the leak diagnostic unit detected by the engine control module (ECM). This fault status corresponds to diagnostic trouble code (DTC) ECM-431D, Signal missing.
