Function Explanation (DTC Detection Outline)

Repeatability Verification Procedure

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_CL_V_POS_R and ENG_CL_V_POS 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.
