This bulletin applies to all Honda vehicles equipped with the millimeter wave radar.
Whenever you’re aiming the millimeter wave radar with the i-HDS, be sure to first perform the mechanical vertical aiming with the rectangular bubble level as called out in the aiming procedure.
If you don’t follow this, you could wind up with a variety of radar-related issues or even a comeback.
If you have misplaced the bubble level (small and easy to lose), you can order one from Mcmaster-Carr at www.mcmaster.com.
The bubble level is listed as a 7/16-inch square rectangular Vial P/N 3338A14. Keep in mind that if you’re aiming the millimeter wave radar on a 2013-2015 Accord or 2014-2015 Accord Hybrid, the procedure calls for the Adaptive Cruise Control (ACC) Sensor Alignment Tool Set (SPX 10243), instead of the bubble level.
