Behind every modern grille sits a millimeter-wave radar feeding ACC, FCW and auto-brake. A single degree off and it tracks the wrong vehicle. We re-aim it to OEM spec, every time, on your floor.
The front radar lives behind the grille or lower bumper and measures distance and closing speed to whatever sits ahead of the vehicle. Adaptive Cruise Control, Forward Collision Warning, and automatic emergency braking all act on its data. A radar that's a degree off doesn't fail loudly. It just locks onto the wrong vehicle, in the next lane, and the driver finds out at the worst moment.
When the front radar needs to be calibrated
- Front bumper or grille replacement
- Radar bracket R&I or replacement
- Front-end collision repair, even minor
- Frame or suspension work near the front structure
How Focal ADAS performs the job
A radar calibration is a static procedure. We place a calibrated reflector or doppler simulator at the exact distance and offset the OEM specifies, level the vehicle to its reference, and drive the radar through its alignment routine on the OEM scan tool. The radar reports its measured offset back, we trim it to spec, and verify with a pass result.
Why a clean scan doesn't replace this
A radar with no fault code can still be physically misaimed: the sensor has no way to know the bumper around it moved. OEM procedures call for calibration based on the operation performed, not the scan result. If the bumper or grille came off, the radar is on the calibration list.
Focal ADAS handles it on-site, same day, from Seattle to Tacoma.
