2. INSPECT BATTERY VOLTAGE

   
   

   1. Measure the battery voltage with the ignition switch off.

      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 (BEAM AXIS MISALIGNMENT READING)*

   
   

   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-OFF) 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.

   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.

   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

7. CHECK FOR DTCs (DYNAMIC RADAR CRUISE CONTROL SYSTEM)

   
   

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

      Click here

   2. Clear the DTCs.

      Click here

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