Confirm the result of the horizontal auto aiming following the onscreen instructions of the HDS.
NOTE: The result of all auto aiming can be confirmed by the HDS, or by watching the MID. When watching the MID, if the auto aiming is confirmed, the MID will display "RADAR OK" with the specification of 100 ±2, and the brake lights will illuminate. When the target is out of auto range, the MID will display "NO TARGET", the brakes will not illuminate, and an audible tone will sound. The auto aiming is not complete. If DTC 120, 121, 122, 123, or 124 is indicated, the aiming target is not set correctly. Inspect the millimeter wave radar mounting for bent or damaged parts. Verify the vertical aiming. Reset the aiming target.

After aiming, clear the DTCs with the HDS (see HOW TO CLEAR DTCS ).
