Monitor Scantool Data

  1. Engine "ON".
  2. Monitor Engine Coolant Temperature Sensor parameter on Current data.
  3. After the engine has been starting, Check that ECT rises steadly to about 90°C (194°F) and ECT stabilizes when the thermostat opens.

    Specification: ECT rises steadly to about 90°C (194°F) and ECT stabilizes when the thermostat opens. (Error range 2~3%)
