DTC Information: DTC Detecting Condition

Item		Detecting Condition	Possible Cause
DTC Strategy		During ECM off (engine off), check that engine off timer is incrementing	ECM
Enable Conditions	Case1	Warmed up condition met at previous DC ECT at previous DC is greater than 55°C (131°F) IAT deviation is greater than 0°C (32°F) (IAT deviation is difference between IAT at key off previous DC and IAT at key on) ECT deviation is greater than 40°C (104°F) (ECT deviation is difference between ECT at key off previous DC and ECT at key "ON") IAT or ECT circuit fault not present
Enable Conditions	Case2	Warmed up condition met at previous DC ECT at previous DC is greater than 55°C (131°F) IAT deviation is greater than 0°C (32°F) (IAT deviation is difference between IAT at key off previous DC and IAT at key on) ECT deviation is greater than 40°C (104°F) (ECT deviation is difference between ECT at key off previous DC and ECT at key "ON") 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)
Threshold Value	Case2	Engine off timer is greater than threshold (engine off timer at key "ON" too fast)
Diagnostic Time		0.01s
MIL ON Condition		2 driving cycles
