I am wondering what exactly the rules are for MIL to come on on a OBD II system.
For example what makes the same exact failure code set to have MIL on at one point in time and MIL off later.
The example code set that gave me MIL on for while, then MIL off for about half day and then MIL on again is
By the way what exactly is the difference between confirmed and pending in a scanner (in particular for ACTRON CP9575) ?
And which one is more recent?
Thank you Tegger.
The car is 2001 Honda Civic EX Coupe, at about 171,000 miles.
There are virtually no detectable misfire symptoms in the engine. It is running almost like a new car. Perhaps with some exhaust noise, I am not sure. Many people drove the car. They expressed there is perhaps misfire but they were not sure.
All monitors were always on when this MIL On,OFF,On happened. That is why I was questioning what I am seeing.
