DTC P1604: Startability Malfunction [08/2016 - ]: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. CHECK ANY OTHER DTCS OUTPUT AND RECORD FREEZE FRAME DATA (IN ADDITION TO DTC P1604) 
    GTY374631Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    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.

      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 then the DTC is stored.

  2. CHECK IMMOBILISER 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 / Primary / Immobilizer Communication and Immobilizer Fuel Cut.

      Powertrain > Engine and ECT > Data List

    5. Check the Data List indication.

      OK

      Data List Item Techstream Display
      Immobilizer Communication ON
      Immobilizer Fuel Cut 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.
