Connect the scan tool to the data link connector(DLC) and start the engine
Fix the mass folw, the EGR actuator and the engine speed in the current data of scan tool
ARE THERE THE MASS AIR FLOE AND THE EGR ACTTUATOR CURRENT DATA PROPERLY DISPLAYED AT THE IDLE WITHIN SPECFICATION ?
SPECIFICATION
MASS AIR FLOW
450 ~ 510 mg/stroke (without EGR operation)
280 ~ 360 mg/stroke (with EGR operation)
EGR SOL. VALVE DUTY RATIO
5 % (opened position) ~ 95 % (closed position)
YES
Go to step 4
NO
Go to " Component Inspection" procedure among the tree on the left-hand side of the window
Recheck the MAF sensor and the EGR system , Go to " DTC 0100 or 0403 "
Fix the VGT actuator, the boost pressure sensor and the throttle actuator in the current data of scan tool
SPECIFICATION
VGT ACUTATOR DUTY RATIO
85% (low speed and low load) ~ 5% (high speed and high load)
BOOST PRESSURE
2500 mbar (Maximum)
THROTTLE ACUTATOR DUTY RATIO
95% (fully closed position) ~ 0% (fully opened position)
① This test should be inspected after keeping the condition of the engine speed with the above 1500 rpm and the fuel injection quantity with above 40 cc
② Keep the above test condition for more than 5 seconds
③ Let it idle and check the current data
IS THERE THE CURRENT DATA PROPERLY DISPLAYED WITHOUT ENGINE SPEED LIMITATION ?
YES
Make sure there is no the DTC in the diagnostic trouble codes menu
NO
Recheck for the wiring/harness of throttle sol.valve and component inspection
Recheck for the wiring/harness of VGT sol.valve and component inspection
Recheck for the wiring/harness of boost pressure sensor and component inspection
Recheck for the wiring/harness of VGT actuator and component inspection
MONITORING FOR PENDING DTC SET ?
YES
Go to the applicable troubleshooting procedure.
NO
System OK
