1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
5. Read the DTCs and record the Freeze Frame Data.

   Powertrain > Engine and ECT > Trouble Codes 

   HINT: 

   • This freeze frame data shows the actual engine conditions when engine starting trouble occurred.
   • When confirming the freeze frame data, be sure to check all 5 data sets of freeze frame data.
   • The fourth set of freeze frame data is the data recorded when the DTC is stored.

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Immobiliser Fuel Cut.

   Powertrain > Engine and ECT > Data List 

   Tester Display
   Immobiliser Fuel Cut

5. Read the value displayed on the Techstream.

   OK

   Immobiliser Fuel Cut is OFF

   HINT: 

   • If the engine is started immediately after reconnecting the battery terminal, the engine may stall immediately after it starts due to the intercommunication process between each ECU. For this reason, when starting the engine after reconnecting the battery terminal, first turn the ignition switch to ON and then wait several seconds for the communication process to complete before starting the engine.
   • When this operation causes DTC P1604 to be stored, this is due to normal operation of the immobiliser system and does not indicate a malfunction, so clear the DTC and return the vehicle to the customer.

   HINT: 

   When DTC P1604 is stored, either "Engine Start Hesitation"*1 or "Low Rev for Eng Start"*2 in the Freeze Frame Data will be ON. If "Low Rev for Eng Start" is ON, proceed to E.

   *1: This value turns ON when the engine speed does not reach a certain value for a certain period of time when starting the engine.

   *2: This value turns ON when the engine stalls immediately after starting the engine. If "Low Rev for Eng Start" is ON, as there is a possibility that the low engine speed or engine stall was caused by the user, confirm the following freeze frame data items.

   • Immobiliser Fuel Cut
   • Engine Speed (Starter Off)

   • *1: The 5 sets of freeze frame data show approximately the same battery voltage.
   • *2: The 5 sets of freeze frame data show different battery voltages.
   • *3: If the voltage fluctuates, it can be determined that cranking is being performed. When the engine speed is 0 rpm, the crankshaft position sensor system and/or the ECM may be malfunctioning.
   • *4: There may be excess engine friction. Make sure that the crankshaft rotates smoothly when turning it by hand. Excess engine friction may have occurred temporarily. Remove the cylinder head cover and oil pan, and check for foreign matter such as iron fragments. If there is a malfunction or signs of a malfunction present, perform a detailed inspection by disassembling all the parts.

   Refer to PROCEDURE - Step 1

   HINT: 

   • If the accelerator pedal is released after racing the engine, the inspection is easier to perform because the vacuum inside the intake manifold increases and the air suction noise becomes louder.
   • If Short FT #1 and Long FT #1 are largely different from the normal values (differ by higher than 15%) when idling (intake air volume is small) and almost the same as the normal values when racing the engine (for example, when maintaining a speed of 3000 rpm) (intake air volume is high), air leakage may be present.
