  2. INSPECT BATTERY VOLTAGE


    1. Measure the battery voltage.

      Standard Voltage
      11 to 14 V

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

  3. 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 ignition switch to ON.

    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.


      Body Electrical > Pre-Collision 2 > Utility
      Tester Display
      Front Beam Axis Adjustment

    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.


      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 -5.2 to 5.2 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

  7. CHECK FOR DTCs*


    1. Check for DTCs and note any codes that are output.


      Powertrain > Cruise Control > Trouble Codes
      Powertrain > Radar Cruise2 > Trouble Codes

    2. Clear the DTCs.


      Powertrain > Cruise Control > Clear DTCs
      Powertrain > Radar Cruise2 > Clear DTCs

    3. Recheck for DTCs. Try to reproduce the DTCs by duplicating the conditions indicated by the DTCs.


      Powertrain > Cruise Control > Trouble Codes
      Powertrain > Radar Cruise2 > Trouble Codes
      Result
