Electronic Control Module (ECM)
Measuring time expired to reach min. coolant temperature(> 55°C) for closed loop operation. Max. time depends on engine start temperature. A fault will be detected if the time limit is reached.
for engine start temp. > -7°C = 500 sec.
for engine start temp. > 10°C = 450 sec.
