Precaution [03/2020 - 10/2020]

  1. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL 
    NOTE:

    When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected.

    System Name See Procedure
    Lane Departure Alert System (w/ Steering Control) Refer to INITIALIZATION [03/2020 - 10/2020]
    Intelligent Clearance Sonar System
    Parking Assist Monitor System
    Panoramic View Monitor System
    Pre-collision System
  2. IGNITION SWITCH EXPRESSIONS 

    The type of ignition switch used on this model differs depending on the specifications of the vehicle. The expressions listed in the table below are used in this article.

    Expression Ignition Switch (Position) Engine Switch (Condition)
    Ignition Switch off LOCK Off (Lock)
    Ignition Switch ACC ACC On (ACC)
    Ignition Switch ON ON On (IG)
    Engine Start START On (Start)
  3. PRECAUTION FOR REPLACING COMBINATION METER ASSEMBLY 

    When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

  4. FUEL RECEIVER GAUGE OPERATION 
    1. Operation

      The combination meter assembly receives the fuel level signal via direct line from the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* and the fuel consumption signal from the ECM via CAN communication, then calculates the fuel level in the fuel tank and displays the calculated value on the fuel receiver gauge.

      1. *: for AWD
    2. Fuel Receiver Gauge Reading
      1. During normal driving:

        During driving, the value of the fuel receiver gauge is updated based on the reduction in the fuel level. The reduction is calculated by deducting the value calculated based on the fuel consumption signal sent by the ECM from the value calculated based on the signal sent by the fuel sender gauge assembly and No. 2 fuel sender gauge assembly*.

        1. *: for AWD
      2. During refueling:

        As the fuel level in the fuel tank increases during refilling, the output value of the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* changes. When the combination meter assembly detects a change in the output value of the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* of a certain value or more, it determines that fuel is being added and calculates the added amount. This control is called refueling judgment and the fuel receiver gauge display is updated in accordance with the fuel level calculated based on the refueling judgement.

        1. *: for AWD
    3. Refueling Judgment Conditions
      NOTE:

      Add fuel with the ignition switch off to ensure safety and to enable refueling judgment so that an appropriate fuel receiver gauge reading will be obtained.

      1. Normal judgment condition (When normal refueling method is used)

        With the ignition switch off, the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.

        1. *: for AWD
      2. Other judgment conditions (When other refueling method is used)

        Any of the following conditions is met:

        • With the vehicle and engine stopped and the ignition switch ON, the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.
        • With the vehicle stopped, the ignition switch ON and the shift lever in P or N, the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.
        • With the vehicle stopped, the ignition switch ON and the shift lever not in P or N, the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* detects a change of 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more in the fuel level.
          1. *: for AWD
    4. Precaution for Refueling
      1. The fuel sender gauge assembly and No. 2 fuel sender gauge assembly* cannot detect changes in the fuel level within certain ranges (around points E, 1/2* and F). Therefore, even if 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more of fuel is added, refueling judgment may not be performed and the fuel receiver gauge reading may not change when fuel level is within such ranges.
        1. *: for AWD
      2. When refueling judgment is performed, it takes up to approximately 25 seconds for the fuel receiver gauge reading to change to the appropriate level.
    5. Forced Reset of Fuel Receiver Gauge

      When driving at a vehicle speed of 20km/h (12 mph) or more, if the fuel level calculated using the signal from the fuel sender gauge assembly and No. 2 fuel sender gauge assembly* is different from the fuel receiver gauge reading by 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more for approximately 2 minutes, the fuel sender gauge assembly reading is immediately updated based on the calculated fuel level.

      1. *: for AWD
  5. SERVICE MODE (w/ Toyota Entune Remote Connect) 
    NOTE:
    • Before servicing, enter service mode to restrain telematics communication functions and prevent the following while servicing:
      • Remote door lock and unlock operations
      • Remote power start and stop operations
      • Warning notification function operations
    • Service mode can be entered by using the Techstream or operating the radio and display receiver assembly.

    HINT: 

    When a warning is generated due to a vehicle malfunction, the DCM (Telematics Transceiver) receives warning information from the combination meter assembly and sends a warning notification to the service center.

    1. Service mode
      1. Enter service mode (Method 1)
        1. Turn the ignition switch off.
        2. Connect the Techstream to the DLC3.
        3. Turn the ignition switch to ON.
        4. Turn the Techstream on.
        5. Enter the following menus: Body Electrical / Telematics
      2. Enter service mode (Method 2)

        HINT: 

        Use the Techstream to cancel communication function pausing mode (Service Mode).

        Refer to UTILITY [09/2019 - ]
