For Misfire (Exhaust Quality Deterioration), Fuel Injection
EXPLANATION FOR DRIVING PATTERNS FOR "MISFIREDriving 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 reset when the malfunction is detected once regardless of the driving pattern.
- The B counter will count up times driving pattern B is satisfied without the malfunction.
- The MIL will go off when the B counter reaches 3. (*2 in "Summary Chart)." Summary Chart
Driving pattern C means the vehicle operation as follows:
(1) 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 (1).
^ The C counter will be counted up when (1) 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 a time without the same malfunction after DTC is stored in ECM.
