Figure 5-7 Sample Frequency of Occurrence Graph
Graph example: Certain faults occur at greater frequency as vehicle mileage increases.
This graph depicts the fault occurrence frequency for the Night View Assist system at
vehicle mileage intervals. Before the mileage reaches 100k miles, the camera internal
fault occurs more frequently than other fault types, with its highest frequency of 10
coming at 70k miles, while line connection fault between control module of Night View
Assist system (N101) and dynamic CAN high distributor X30/28 occurs as frequently as
10 at 90k miles. As the mileage approaches 110k miles, the occurrence of the two
faults drops, giving way to Night View Assist system control module fault which, after
reaching 9 at 110k miles, starts to decline at the same point. Another line fault between
camera (B84/2) and control module of Night View Assist (N101), poses not much threat
in the previous 110k miles, but it boasts a maximum occurrence of 8 when the vehicle
travels 130k miles. Similarly, the power supply fault of control module of Night View
Assist (N101) becomes most worrisome at 150k miles.
In conclusion, the graph provides a convenient reference for locating possible faults of
the Night View Assist function in accordance with the driving mileage.
