Explanation For Driving Patterns For "Misfire <Exhaust Quality Deterioration>", "Fuel Injection System"

WARNING: This page is about a different car, the 2008 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

Driving pattern B means the vehicle operation as follows:

All components and systems should be monitored at least once by the OBD system.

The B counter will be cleared when the malfunction is detected once regardless of the driving pattern.
The B counter will be counted up when driving pattern B is satisfied without any malfunction.
The MIL will go off when the B counter reaches 3. (^*2 in "OBD SYSTEM OPERATION CHART")

Driving pattern C means the vehicle operation as follows:

The following conditions should be satisfied at the same time:

Engine speed: (Engine speed in the freeze frame data) ±375 RPM

Calculated load value: (Calculated load value in the freeze frame data) x (1 ± 0.1) [%]

Engine coolant temperature (T) condition:

When the freeze frame data shows lower than 70°C (158°F), T should be lower than 70°C (158°F).
When the freeze frame data shows higher than or equal to 70°C (158°F), T should be higher than or equal to 70°C (158°F).

Example:

If the stored freeze frame data is as follows:

Engine speed: 850 RPM, Calculated load value: 30%, Engine coolant temperature: 80°C (176°F)

To be satisfied with driving pattern C, the vehicle should run under the following conditions:

Engine speed: 475 - 1, 225 RPM, Calculated load value: 27 - 33%, Engine coolant temperature: more than 70°C (158°F)

The C counter will be cleared when the malfunction is detected regardless of vehicle conditions above.
The C counter will be counted up when vehicle conditions above is satisfied without the same malfunction.
The DTC will not be displayed after C counter reaches 80.
The 1st trip DTC will be cleared when C counter is counted once without the same malfunction after DTC is stored in ECM.
