ECU Fault Finding

Question:

What is the relationship between Current Faults and Logged Faults in Easimap 6. Presumably a fault will disappear from Current Faults as soon as the condition is resolved, but does it then remain in Logged Faults? How long do they remain in Logged Faults for? And is there a way to clear or reset the Logged Faults?

Answer:

The 9A* range of ECUs has the option to display current faults and logged faults. The current faults will only exist while it actually has that fault and then the status will return to being ok. The logged fault will only log the fault until the ECU power has been cycled.

This way if you wish to diagnose a fault and the fault is intermittent, you may miss it in the current faults section, but it would be obvious in the logged fault provided you do not cycle the ECU power.
