      Note

      
      

      • Ensure that nobody enters the adjustment area during the adjustment.

      • Do not turn off the GTS or engine switch.

      • Do not move or shake the vehicle during adjustment (do not get in or out of the vehicle).

      • Close all of the doors.

      
      

      1. Enter the following menus:

         Body Electrical / Pre-Crash 2 / Utility.

      2. According to the display on the GTS, press "Next".

      3. Perform the adjustment according to the display on the GTS.

         Specified Condition:

         Vertical	-0.5 to 0.5 deg
         Horizontal	-0.6 to 0.6 deg

         Note

         If the result is not as specified, perform beam axis adjustment again.

         If the result is not as specified, perform beam axis adjustment again.

      4. Turn the engine switch off.

      5. Disconnect the GTS from the DLC3.

3. MANUALLY CHANGE BEAM AXIS OF MILLIMETER WAVE RADAR SENSOR ASSEMBLY

   Note

   
   

   • Manually change the beam axis when error code 12 (radar axis aiming failure upward), 13 (radar axis aiming failure downward) or 1 (no target abnormality) is displayed.

   • If the beam axis change mechanism is in the most upward or downward position, check for DTCs.

   • If no DTCs are output, repair or correctly install the front bumper assembly.

   Tech Tips

   The millimeter wave radar sensor assembly is fixed to the front bumper assembly. If the installation position of the front bumper assembly is misaligned, the beam axis will also be misaligned. Therefore, when the front bumper assembly is deformed, even if the millimeter wave radar sensor assembly beam axis is manually changed or the millimeter wave radar sensor assembly is replaced, the millimeter wave radar sensor assembly beam axis adjustment may not complete.

   2. Turn the bolt to change the beam axis of the millimeter wave radar sensor assembly.

      Torque:

      1.5 N*m  { 15 kgf*cm, 13 in.*lbf }

      Note

      The beam axis change mechanism may be damaged if torque exceeding the specified amount is applied.
