DTC DETECTING CONDITION CHART
| ITEM |
Detecting Condition |
Possible Cause |
| DTC Strategy |
Case 1 |
- Determines if Delivered Torque Is Grossly Different from Desired Torque
|
- Intake air leakage
- Faulty ETS System
- Clogged exhaust system
- Faulty PCM
|
| Case 2 |
- Determines if Delivered Torque is Grossly Different from Desired Torque
|
| Case 3 |
- Determines if Delivered Torque is Greater than Desired Torque With Zero Pedal
|
| Enable Conditions |
Case 1 |
|
| Case 2 |
- Engine Running state
- Engine Speed > 600rpm
- Desired Flywheel Torque Within 20Nm
- Steady State Torque Timer > 1sec.
|
| Case 3 |
- Pedal Position < 0.8%
- Torque Command Source = Engine off
|
| Threshold value |
Case 1 |
- When Dynamic torque error (difference between actual and desired torque value) above which the torque too high fail criteria is met > 25%While Net Torque ≥ 20Nm OR torque throttle load > 1%
|
- Dynamic Torque Error The torque error (difference between actual and desired torque value) below which the torque too low fail criteria is met < -120%While Desired ETC throttle position < 0%
|
| Case 2 |
- When Steady State Torque Error > 60Nm While Actual Net Torque ≥ 20Nm OR Torque Throttle Load ≥ 2%
|
| Case 3 |
- Maximum limit for the fuel flow rate to pass theredundant torque rationality diagnostic versus engine speed. > 3g/s
|
| Diagnosis Time |
Case1: More than 7.8sec. failure for every 15.6sec.TestCase2: More than 0.03sec. failure for every 0.6sec.TestCase3: More than 7.8sec. failure for every 15.6sec.Test |
