Detecting Condition |
Possible Cause |
| DTC Strategy |
- During ECM off (engine off), check that engine-off timer is incrementing
|
|
| Enable Conditions |
Case1 |
- Warmed up condition met at previous DC
- ECT at previous DC is greater than 70°C (158°F)
- IAT deviation is greater than 0°C (32°F) (IAT deviation is difference between IAT at key off previous D/C and IAT at key on)
- ECT deviation is greater than 40°C (104°F) (ECT deviation is difference between ECT at key off previous D/C and ECT at key on)
- IAT or ECT circuit fault not present
|
| Case2 |
- Warmed up condition met at previous DC
- ECT at previous DC is greater than 70°C (104°F)
- IAT deviation is less than 40°C (32°F)
- ECT deviation is less than 20°C (68°F)
- IAT or ECT circuit fault not present
|
| Threshold Value |
Case1 |
- Engine-off timer is less than threshold (Engine off timer at key "ON" too slow)
|
| Case2 |
- Engine-off timer is greater than threshold (Engine off timer at key "ON" too fast)
|
| Diagnostic Time |
- 10 ms (Once per driving cycle)
