Question

On the diagnostic machine, there are different types of codes that show on a vehicle. Sometimes it can be as active/ confirmed (meaning that the vehicle computer confirmed that it is a fault and not just a once off issue) Then it can be as pending, meaning it may have occurred once or twice but the issue didn't occur enough times over a certain period of drive cycles. So, my question is that it is it necessary to mention those faults that have occurred as 'pending' to the customer because from a driving point of view the car doesn't feel like there is an issue in the area marked as 'pending'. And there is no engine light.
