Diagnostic help

The diagnostic trouble code is generated if a fault is found during two test cycles in succession. A test cycle lasts one second, i.e. it takes two seconds from when the fault occurs until a diagnostic trouble code is generated. If the fault disappears, the trouble code is deleted from the control module memory after the ignition has been turned on 20 times.
