| Enable Conditions |
Case 1 |
- ECT at stop previous driving cycle is over 70°C
(158°F) (Warmed up condition met at previous driving cycle)
- IAT difference is over 0°C (32°F)
(IAT at ignition "OFF" previous driving cycle - IAT at ignition "ON")
- ECT difference is over 40°C (104°F)
(ECT at ignition "OFF" previous driving cycle - ECT at ignition "ON")
- IAT or ECT circuit fault is not present
