DTC P2583-76

DTC P2583-76  : Temporary stop of Integrated Driver Support System (Misalignment Millimeter Wave Radar)

NOTE: 

• Before you troubleshoot, review the general troubleshooting information .
• Before you troubleshoot, make sure all the tire pressures are correct, and remove all the cargo from the vehicle.
• This DTC is recorded if the beam axis of the millimeter wave radar gets out of alignment as follows while the vehicle is driving.
• • Vertical direction: 3.0 degrees or more
  • Horizontal direction: 2.5 degrees or more
• If this DTC is recorded, the following is suspected:
• • Change in the vehicle posture caused by an overload or the vehicle being towed.
  • It has been detected that the beam axis of the millimeter wave radar is out of alignment due to improper installation.
  • The millimeter wave radar installing portion is deformed by a minor collision or strong impact.
  • The beam axis of the millimeter wave radar is out of alignment due to abnormal wheel alignment, abnormal tire pressure, etc.
  • Altered suspension
  • When it is snowing, the radio waves transmitted and received by the millimeter wave radar may be refracted by the snow or ice attached around the millimeter wave radar such as the front grille, and are detected as a misalignment.
• If this DTC is recorded, the integrated drive support system temporarily cancels its control to prevent excessive operation or malfunction.
• Even when this DTC is recorded, the vehicle returns to normal if the misalignment of the detection axis of the millimeter wave radar is 1.5 degrees or less.
• The functions of the integrated driver support system that will be temporarily canceled when this DTC is recorded can be confirmed with the DTC troubleshooting index .

DTC (IDAS)

1. Check the vehicle condition

   -1. Turn the vehicle to the ON mode.

   -2. Check if any integrated driver support system related indicator comes on in the gauge control module.

   Is any indicator currently comes on?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   The system is OK at this time. Clear the DTC with the HDS. If the indicator is turned off, and axis misalignment has been recorded, explain to the customer that the system detected a temporarily misaligned millimeter wave axis and stopped functioning.

2. Millimeter wave radar installation check

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Remove the front bumper .

   -3. Check that the millimeter wave radar and radar bracket are installed properly and check them for deformation and damage.

   Are the millimeter wave radar and the radar bracket installed properly, and/or there are no signs of damage?

   YES 

   Aim the millimeter wave radar . After the millimeter wave radar aiming is complete, clear the DTC with the HDS.

   NO 

   Repair or replace faulty parts, then aim the millimeter wave radar .
