  1. Warm up the engine to allow the engine coolant temperature to reach 50-95°C {122-203°F}.
    NOTE:
    • The difference between PIDs ENG_COOL_VLV_POS_ACT and ENG_COOL_VLV_POS_COMD displayed the engine coolant control valve opening angle must be within 2°.
    • Match the engine coolant temperature in the recorded freeze frame data/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.
  2. Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the freeze frame data/snapshot data.
