See step  4

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Using the Techstream, confirm the vehicle conditions recorded in the freeze frame data which were present when the DTC was stored.

   Powertrain > Engine > DTC(P0087-00) > Freeze Frame Data 

   Tester Display
   Target Fuel Pressure (Low) / Target Fuel Pressure 2
   Low Fuel Pressure Sensor

   HINT: 

   • Check the freeze frame data sets recorded the moment the DTC was stored and after the DTC was stored.
   • Using the freeze frame data, confirm the vehicle conditions when the DTC was stored, such as if the engine was idling with the shift state P, D or N or if the vehicle was being driven at a constant speed or accelerating.
5. Compare the difference in pressure between "Target Fuel Pressure (Low) / Target Fuel Pressure 2 and Low Fuel Pressure Sensor".

   Result

   Result	Proceed to
   Difference between Target Fuel Pressure (Low) / Target Fuel Pressure 2 and Low Fuel Pressure Sensor is within 200 kPa	A
   Difference between Target Fuel Pressure (Low) / Target Fuel Pressure 2 and Low Fuel Pressure Sensor is more than 200 kPa	B

Result: 

B 

GO TO FUEL PUMP CONTROL CIRCUIT. Refer to  Fuel Pump Control Circuit [06/2018 - 08/2021] 

Result: 

A 

See step  5

1. Connect the Techstream to the DLC3.
2. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Active Test / Control the Injection Mode / Direct / Data List / Coolant Temperature, Injection Mode and Misfire Count Cylinder #1 to Misfire Count Cylinder #6.

   Powertrain > Engine > Active Test 

   Active Test Display

   Misfire Count Cylinder #4
   Misfire Count Cylinder #5
   Misfire Count Cylinder #6

5. According to the display on the Techstream, read the Data List with the Active Test "Control the Injection Mode" set to Direct.

   Result

   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 direct fuel injector assembly.

   Refer to INITIALIZATION [06/2018 - 07/2019] , or refer to INITIALIZATION [07/2019 - ]
