EGR Valve Operation Inspection

Verify that the MAP sensor is normal. Refer too MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-G 2.5T] .)
Connect the M-MDS to the DLC-2.
Start the engine.
Access the following PCM PIDs using the M-MDS. Refer too ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .)
- SEGRP
- SEGRP_DSD
Verify the SEGRP PID value when the simulation item SEGRP_DSD increases from 0 % to 100 %.
- If the SEGRP does not operate:
  - Perform the EGR valve resistance inspection. Refer too EGR VALVE INSPECTION [SKYACTIV-G 2.5T] .)
