If simulation function of M-MDS is used:

Start the engine and run it is idling.
Disconnect the hose between the wastegate control solenoid valve and the intake pipe.
Put a finger to the wastegate control solenoid valve and verify that there is no pressure applied.
- If there is pressure, inspect the following:
  - Wiring harness and connectors (Wastegate control solenoid valve-PCM terminal 2AA)
  - Wastegate control solenoid valve (Stuck open)
Warm up the engine to normal operating temperature.
Connect the M-MDS to the DLC-2 and verify that DTC P0245 or P0246 are shown. Perform the DTC inspection.
(See DTC P0245 .)

(See DTC P0246 .)
Select the VGT PID.
Increase the duty value of the wastegate control solenoid valve and inspect if the operation sound of the solenoid valve is heard.
- If the operation sound is heard, inspect for loose or damaged vacuum hoses. (Wastegate actuator - wastegate control solenoid valve - intake hose)
- If the operation sound is not heard, perform the wastegate control solenoid valve inspection.
Warm up the engine to normal operating temperature.
Monitor the VGT and APP PIDs using the M-MDS.
Run the engine with the APP PID above 30% and verify that the VGT PID value increases from 0% .
- If the VGT PID is 0% , inspect the APP PID.
