Monitor description
. The powertrain control module will set a DTC if the engine off time calculated from the global time in the instrument cluster/body control module is less than 1hr, when the shutdown temperature was fully warm, and the coolant 1 temperature at start is significantly cooled down to ambient temp
- Vehicle battery has been isolated and the global time does not increment. Warm coolant has been replaced with cold coolant
- Rapid engine temperature cooling with rapid ambient temperature rise
