I own an NC1, but this question is applicable to any model.
Is it sensible to plug in the dongle and do an ODB2 scan for stored faults every now and then to detect any ‘invisible’ lurking problems or do all faults which would be flagged give a dash indication at the time they occur?
I do our cars just prior to a service.
‘Knowledge is power’
Pending codes can be stored, these are potential faults that will only cause the MIL to come on if they are detected on consecutive drive cycles.
I presume that in this context, MIL means something other than mother-in-law?
Malfunction Indicator Light, the EOBD standard name for what people call the engine light.
Thank you for that clarification
