Nissan Sentra Service Manual / Engine / Engine control system / Operation / Diagnosis description : driving pattern

DRIVING PATTERN A

Driving pattern A means a trip satisfying the following conditions.

Engine speed reaches 400 rpm or more.
Engine coolant temperature rises by 20В°C (36В°F) or more after starting the engine.
Engine coolant temperature reaches 70В°C (158В°F) or more.
The ignition switch is turned from ON to OFF.

NOTE:

When the same malfunction is detected regardless of driving conditions, reset the counter of driving pattern A.
When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving pattern A.

DRIVING PATTERN B

Driving pattern B means a trip satisfying the following conditions.

Engine speed reaches 400 rpm or more.
Engine coolant temperature reaches 70В°C (158В°F) or more.
Vehicle speed of 70 вЂ“ 120 km/h (44 вЂ“ 75 MPH) is maintained for 60 seconds or more under the control of closed loop.
Vehicle speed of 30 вЂ“ 60 km/h (19 вЂ“ 37 MPH) is maintained for 10 seconds or more under the control of closed loop.
Under the closed loop control condition, the following state reaches 12 seconds or more in total: Vehicle speed of 4 km/h (2 MPH) or less with idling condition.
The state of driving at 10 km/h (7 MPH) or more reaches 10 minutes or more in total.
A lapse of 22 minutes or more after engine start.

NOTE:

Drive the vehicle at a constant velocity.
When the same malfunction is detected regardless of driving conditions, reset the counter of driving pattern B.
When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving pattern B.

DRIVING PATTERN C

Driving pattern C means operating vehicle as per the following: The following conditions should be satisfied at the same time:

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

Calculated load value: (Calculated load value in the freeze frame data) x (1В±0.1) [%] Engine coolant temperature condition:

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

NOTE:

When the same malfunction is detected regardless of the above vehicle conditions, reset the counter of driving pattern C.
When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving pattern C.
The 1st trip DTC will be cleared when C counter is counted once without the same malfunction after DTC is stored in ECM.

DRIVING PATTERN D

Driving pattern D means a trip satisfying the following conditions

The state of driving at 40 km/h (25 MPH) reaches 300 seconds or more in total.
Idle speed lasts 30 seconds or more.
A lapse of 600 seconds or more after engine start.

NOTE:

When the same malfunction is detected regardless of driving conditions, reset the counter of driving pattern D.
When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving pattern D.
