DIAGNOSIS SYSTEM (ECM) EC-55 < SYSTEM DESCRIPTION > [HR16DE] C D E F G H I J K L M A EC N P O Explanation for Driving Patterns Except for “Misfire <Exhaust Quality Deterioration>”, “Fuel Injection Driving Pattern A EC-55, "DIAGNOSIS DESCRIPTION : Driving Pattern" . Driving Pattern B EC-55, "DIAGNOSIS DESCRIPTION : Driving Pattern" . DIAGNOSIS DESCRIPTION : Driving Pattern INFOID:0000000009267017 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 20 °C (36°F) or more after starting the engine. • Engine coolant temperature reaches 70 °C (158°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 70 °C (158°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) ±375 rpm *1: When the same malfunction is de- tected in two consecutive trips, MIL *2: MIL will turn OFF after vehicle is driv- en 3 times (pattern B) without any *3: When the same malfunction is de- tected in two consecutive trips, the *4: The DTC and the freeze frame data will not be displayed any longer after *5: When a malfunction is detected for the first time, the 1st trip DTC and the *6: 1st trip DTC will be cleared after vehi- cle is driven once (pattern B) without *7: When the same malfunction is de- tected in the 2nd trip, the 1st trip |
