The ECM enables oil level and temperature measurement if and only if the following conditions are
satisfied:
Engine idling
Engine oil temperature when the engine is switched off in the range 80°C-90°C.
Engine running in the previous cycle for no less than 5 minutes*
Time for which the engine remained off not less than 3 minutes*
Current temperature (meaning the oil temperature at the KEY ON time. The useable range is
very wide.)
Longitudinal and lateral accelerations below certain thresholds (any slopes on which the car is
parked are interpreted by the control unit as lateral or longitudinal accelerations)
