Honda Some Driver Assist Systems Cannot Operate. ADAS Calibration From $300 Per System.
Is your Honda showing "Some Driver Assist Systems Cannot Operate: Radar Obstructed"? A wipe often clears it; if not, we find the cause and re-aim the camera or radar so it sees straight ahead, nationwide. Send your VIN for a quote.
- Your quote is confirmed in writing before anything is scheduled.
- Calibration runs to full manufacturer specification.
- A calibration certificate after the job.
Is it safe to drive with this message on?
You can drive, but don't rely on the assists listed below. Your brakes and steering work as normal.
- What switches off: collision braking and distance-keeping cruise. Camera messages can stop lane keeping too.
- After a hard knock up front: have the sensors checked before you rely on them.
- If it won't clear: drive as if those features are off, and leave more room.

Some Driver Assist Systems Cannot Operate: what each second line means
On a Honda, this message is Honda Sensing saying its camera or radar can't see. The second line says why:
- Radar Obstructed: snow, mud or bugs over the radar, or bad weather. Wipe its spot:
- 2017 to 2022 CR-V: the front grille.
- 2019 Civic Sedan: the lower bumper.
- 2019 Pilot: the emblem.
- Clean Front Windshield: dirt or fog where the camera looks through the glass. Newer models add "or poor viewing condition".
- Camera Temperature Too High: a sun-baked cabin. Cool it, then drive.
- Clean area shown (2026 Passport): the radar's patch of grille is covered.

Try these before you book
Go down the list in order. Glass or front-end work just before it started? Skip to the prices.
- Park somewhere safe. Wipe the windshield, grille and emblem with a soft cloth.
- Use water or a mild detergent, not solvents or polish.
- Hot cabin? Run the air conditioning, with the defroster aimed at the glass.
- Drive a while. The message should go once the camera or radar can see.
- Still there? Get a quote with the exact words on the dash.

What re-aiming a Honda sensor costs
New windshield? That's the camera. Radar taken off, or bumper work within about 12 inches of it? That's the radar. Cleaning costs nothing.
Calibration, per system
Diagnostic scan
- Same price on a mobile visit, except rows marked Shop bay only.
- Prices are before sales tax. Whether labor is taxed depends on your state; any tax that applies is itemized on your written quote.
- Dynamic calibration runs on the road, so it can be done as a mobile visit. Static calibration needs a level, lit, measured space, so whether your job can be done mobile depends on what your car's documented procedure calls for.
- Rows marked Shop bay only are done in a shop bay. The bay-and-road camera price applies when your car needs both calibrations.

Know your Honda's driver assist messages
When a Honda Sensing message keeps coming back after cleaning, here's why and what fixes it.
If it returns on a clean car, something still blocks the view, or a sensor moved. Common causes:
- The wrong grille or emblem base. They differ by trim, and the wrong one blocks the radar.
- Paint or a wrap on the radar cover, emblem or grille.
- Something stuck on the windshield, hood or grille, like film or a sticker.
- Scratches or aftermarket glass in front of the camera.
- A sensor moved by front-end work, or a radar bracket bent in a light knock.
Fix the first four before any aiming, or it can fail.

Cleaning never needs a calibration, which Honda calls aiming. These repairs do, priced at a service center:
- Camera, $300: a new or refitted windshield, or the camera taken out.
- Radar, $330: taken off and refitted, or bumper repair within about 12 inches (300 mm) of it.
- A new camera or radar: priced on its own line on your quote.
- Camera and radar: an airbag that went off, or structural repair. See ADAS calibration after collision repair.
A wheel alignment alone needs neither, unless the service manual says so.

A scan reads the codes the car stored. These four point at a Honda's camera or radar:
| Code | What it means |
|---|---|
| P2583-97 | Dirt or dust found on the radar |
| P2583-54 | Radar aiming not finished |
| B2A60-52 | Camera aiming on a road drive not finished |
| B2A60-54 | Camera aiming at a fixed target not finished |
Other codes get fixed first, or aiming can fail. A diagnostic scan, when your job needs one, is priced and itemized separately.

Codes are read, then the glass, grille and emblem checked. Wrong or painted parts need replacing before aiming. Your quote says so.
A camera aims at a target in a lit bay, or on a road drive. Your quote names which.
After a collision, the alignment is checked before aiming. See front radar calibration and windshield camera calibration.

The 2020 Acura TLX prints the same message and second lines under AcuraWatch. More on Acura calibration.
Its quick guide clears them the same way:
- Wipe the covered area with a soft cloth.
- Cool a hot camera with the climate control. The defroster sends air toward it.
The 2022 Civic has no front radar. Its driver assist runs on the camera alone.
Other makes word a blocked radar their own way. See front radar sensor blocked.
Only a collision warning light, with no message? See forward collision warning light.

Some Driver Assist Systems Cannot Operate: your questions
Clean and cool first. Wipe the windshield, grille and emblem, cool a hot cabin, then drive a while.
Calibrate if it keeps coming back on a clean car, or after glass or front-end work. Then get a quote with the message.
On a 2017 to 2022 CR-V or a 2018 Accord, there's no reset button. The message clears once the radar can see again.
Wipe the grille, then drive. It can take a while to go off. Still on after that? Get a quote with the full message.
It can be. A new windshield means the camera has to be re-aimed, and aftermarket glass can make the aiming fail.
Re-aiming the camera is $300. More on ADAS calibration after windshield replacement.
Cleaning is free. Front camera calibration is $300 and front radar calibration is $330 at a service center.
Prices are per system, before sales tax where your state charges it on labor, and the full rate card is on the pricing page.
Something is still wrong. Common causes are a painted or wrong grille part, aftermarket glass, or a radar mount bent in a light knock.
The service center checks those first. Your quote is confirmed in writing before anything is scheduled.
Check your policy. If a glass or collision claim came first, ask your insurer whether the calibration falls under it.
Your quote gives the camera or radar its own price line. You can send it straight to the adjuster.
