Diagnosis description : driving pattern

CAUTION:

Always drive at a safe speed.

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 20C (36F) or more after starting the engine.
• Engine coolant temperature reaches 70C (158F) 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 70C (158F) 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) +-375 rpm

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

Engine coolant temperature condition:

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

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.
