Driving Pattern "C"
Driving pattern "C" means the vehicle operation is as follows. The following conditions should be satisfied at the same time:
- Engine Speed - Engine speed in the freeze frame data, plus or minus 375 RPM.
- Calculated Load Value - Calculated load value in the freeze frame data multiplied by 0.9-1.1 percent.
Engine coolant temperature ("T") conditions:
- When freeze frame data shows lower than 158°F (70°C), "T" should be lower than 158°F (70°C).
- When the freeze frame data shows higher than or equal to 158°F (70°C), "T" should be higher or equal to 158°F (70°C).
Example - If the stored freeze frame data is as follows:
- Engine speed is 850 RPM.
- Calculated load value is 30 percent.
- Engine coolant temperature is 176°F (80°C).
To be satisfied with driving pattern "C", the vehicle should run under the following conditions:
- Engine speed is 475-1225 RPM.
- Calculated load value is 27-33 percent.
- Engine coolant temperature is more than 158°F (70°C).
- The "C" counter will be cleared when the malfunction is detected regardless of vehicle conditions above.
- The "C" counter will be counted up when the vehicle conditions above 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 once without the same malfunction after DTC is stored in ECM.
