Case 1: 
  • Engine Coolant Temperature (ECT) between 35 and 60°C (95 and 140°F) when engine started, and conditions (a) and (b) met (2 trip detection logic)
    • (a) Vehicle driven at varying speeds (accelerated and decelerated)
    • (b) ECT remains within 3°C (5.4°F) of initial ECT

Case 2: 
  • ECT more than 60°C (140°F) when engine started, and conditions (a) and (b) met (6 trip detection logic)
    • (a) Vehicle driven at varying speeds (accelerated and decelerated)
    • (b) ECT measurements remain within 1°C (1.8°F) of initial ECT on 6 successive occasions
