    INSPECT AUXILIARY BATTERY VOLTAGE


    1. Measure the auxiliary battery voltage with the power switch off.

      Standard voltage
      11 to 14 V (Power switch off)

      If the voltage is below 11 V, replace or recharge the auxiliary battery before proceeding to the next step.

    INSPECT MILLIMETER WAVE RADAR SENSOR ASSEMBLY*


    1. Adjust the reflector height.

      Click here

    2. Place the reflector.

      Click here

    3. Connect the GTS to the DLC3.

    4. Turn the power switch on (IG).

    5. Turn the GTS on.

    6. Turn the cruise control main switch on.

    7. Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Misalignment Reading.

    8. Check the amount of misalignment and make a note.


      1. Body Electrical > Pre-Collision 2 > Utility
        Tester Display
        Front Beam Axis Misalignment Reading




    9. Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Offset Reading.

    10. Check the amount of misalignment and make a note.


      1. Body Electrical > Pre-Collision 2 > Utility
        Tester Display
        Front Beam Axis Offset Reading




    11. Calculate the "Dealership Axis Offset Angle (with On-line Calibration Angle)" using the values "Front Beam Axis Misalignment Reading" and "Front Beam Axis Offset Reading".


      1. "Dealership Axis Offset Angle (with On-line Calibration Angle)" = "Front Beam Axis Misalignment Reading" - "Front Beam Axis Offset Reading"

        Standard
        Dealership Axis Offset Angle (with On-line Calibration Angle)
        Vertical -2.2 to 1.6 deg.
        Horizontal -0.6 to 0.6 deg.
      Result
      Result Proceed to
      The dealership axis offset angle (with on-line calibration angle) is within the specified range. A
      The dealership axis offset angle (with on-line calibration angle) is not within the specified range. B
