DTC P1604: Startability Malfunction [08/2017 - 08/2018]: Procedure

WARNING: This page is about a different car, the 2018 Toyota Sequoia, 2017 Toyota Sequoia, and 2016 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK ANY OTHER DTCS OUTPUT AND RECORD FREEZE FRAME DATA 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
    4. Read the DTCs and record the Freeze Frame Data.

      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.

      RESULT

      Result Proceed to
      Only DTC P1604 is output A
      DTCs other than P1604 are output B

    Result: 

    B 

    GO TO DTC CHART 

    (Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2017 - 08/2018] )

    Result: 

    A 

    See step  2

  2. CHECK ENGINE IMMOBILIZER SYSTEM 
    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 / All Data / Immobilizer Fuel Cut.
    5. Read the value displayed on the Techstream.

      OK

      Immobilizer 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 immobilizer system and does not indicate a malfunction, so clear the DTC and return the vehicle to the customer.

    Result: 

    NG
