Valve Clearance Inspection And Adjustment Inspect and adjust the valve clearance when the engine is cold (Engine coolant temperature : 20°C(68°F)) and cylinder head is installed on the cylinder block.
Inspection Tolerance Calibration Tolerance calibration compensates for the error margins of surround view video that occur due to the installation tolerance when the four cameras that comprise the SVM system are installed. You must carry out tolerance calibration if you do any of the following.
Inspection 1. Ignition "OFF". 2. Disconnect the intake actuator connector. 3. Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 7. 4. Verify that the intake actuator operates to the fresh position when connecting in the reverse.
