Result: 

NO 

See step  4

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON and turn the Techstream on.
3. Start the engine and warm it up.
4. Enter the following menus: Powertrain / Engine / Active Test / Control the Injection Mode / Direct / Data List / Injection Mode and Misfire Count Cylinder #1 to Misfire Count Cylinder #6.

   Powertrain > Engine > Active Test 

   Active Test Display
   Control the Injection Mode

   Data List Display
   Injection Mode
   Misfire Count Cylinder #1
   Misfire Count Cylinder #2
   Misfire Count Cylinder #3
   Misfire Count Cylinder #4
   Misfire Count Cylinder #5
   Misfire Count Cylinder #6

   HINT: 

   • When using the "Control the Injection Mode" Active Test to check the condition of the engine, switch from "Port" to "Direct".
   • Do not switch from "Direct" to "Port". When performing the inspection more than once, after the Active Test ends, lightly race the engine, and then perform the inspection from "Port" again.
   • If the display does not switch from "Port" even after lighting racing the engine, idle the engine for approximately 1 minute, and then lightly race the engine.
5. Monitor all of the Misfire Count values that are displayed on the Techstream.

   Injection Mode	Misfire Count	Proceed to
   Direct	No misfire counts, or misfire counts occur randomly in all cylinders	A
   	Misfire counts occur in a particular cylinder	B

   HINT: 

   Perform "Inspection After Repair" after replacing the fuel injector assembly (for direct injection).

   Refer to INITIALIZATION [11/2016 - ]

Result: 

B 

REPLACE FUEL INJECTOR ASSEMBLY (FOR DIRECT INJECTION). 

Refer to  REMOVAL [11/2016 - ] 

Result: 

A
