| DTC Strategy |
- Calculation of Engine Roughness
|
- Poor Connector Connection
- Incorrect Valve Timing
- Uneven Compression
- Air Leakage
- Improper Fuel Pressure or Dirty Fuel
- Blocked/Leaking Injectors
- Leakage Between Cooling System and System

| Enable Condition |
Case 1 |
- Engine load ratio more than 15 to 98% depends on engine speed and ECT
- Engine speed higher than 470 RPM and lower than 6200 RPM
- Barometric pressure is higher than 750hPa
- Engine load ranges from 0% to 60%
- Throttle gradient/sec. is less than 58.6 to1265.6 ° TPS/s
