Nissan Sentra Service Manual: 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 – 120 km/h (44 – 75 MPH) is maintained for 60
seconds or more under the control of
closed loop.
- Vehicle speed of 30 – 60 km/h (19 – 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.
