2025-2026 Acura ADX ADAS Camera & Radar Sensor Explained
A guide to diagnosing, replacing, and calibrating the forward camera and rear blind spot sensors for the first-generation Acura ADX.
- Professional ADAS calibration is mandatory after replacing any forward camera or rear radar sensor; this is not a DIY job.
- The provided part numbers refer to different components: a forward camera for lane keeping/collision mitigation and rear radar sensors for blind spot monitoring. Verify the exact number on your old part.
- The most common cause of blind spot sensor malfunction is dirt, snow, or ice on the rear bumper; always clean the area thoroughly before assuming the part has failed.
- Due to the vehicle's newness, used OEM parts are a viable alternative to expensive new dealer parts, but must be inspected carefully for any physical damage.
Camera or Radar? Identifying Your Part
The ADAS systems on the 2025-2026 Acura ADX use several different components that can be confused with one another. The term "Video Camera" most often refers to the forward-facing camera, but the part numbers provided also include the rear blind spot radar sensors. It is critical to identify the correct part for your needs before purchasing.
Warning: The part numbers listed cover different components with distinct functions. 8S10... numbers typically refer to the forward-facing camera, while 8S41... numbers are for the rear blind spot radar sensors. Always verify the part number on your original unit before ordering a replacement.
| Part Number | Component Name | Location | Primary Function |
|---|---|---|---|
| 8S103-3BH-A02 | Lane Assist Camera / Mono Camera Set | Front Windshield, behind rearview mirror | Lane Keeping Assist, Collision Mitigation |
| 8S410-3BH-A01 / 8S411-3BH-A01 | Radar Sub-Assembly, Rear | Rear Bumper, Corners (Left or Right) | Blind Spot Information, Cross Traffic Monitor |
| 8S100-3BH-A02 | Audio Unit Screen | Dashboard | This is the central display screen, not an ADAS camera. |
Symptoms of Failure
Because the ADX is a new model, widespread failure patterns have not yet emerged. However, symptoms for ADAS components are generally consistent across all vehicles.
Forward Camera Failure
- Warning Messages: You will likely see messages on the dashboard such as "Collision Mitigation System Problem," "Road Departure Mitigation System Problem," or "Lane Keeping Assist System Problem." 🎬 Watch: See how these front camera warning messages appear on-screen.
- Disabled Safety Features: Adaptive Cruise Control (ACC) and Lane Keeping Assist (LKAS) will become unavailable.
- Erratic Behavior: In rare cases, a failing camera could provide false warnings or, in extreme situations, cause phantom braking events where the car brakes for no reason.
- Environmental Triggers: Glare from the sun at certain angles, or extremely high heat, can sometimes cause temporary camera malfunctions.
Rear Radar Sensor Failure
- Warning Messages: A "Blind Spot Info System Problem" or similar message will appear on the instrument panel.
- Indicator Light Issues: The small warning light in the side mirror may stay on constantly, or never illuminate when a car is in your blind spot.
- Inoperative Cross Traffic Monitor: The system will fail to alert you to approaching vehicles when you are backing out of a parking space.
- Obstructions: The most common cause of failure is simple obstruction. Dirt, mud, snow, or ice on the rear bumper can block the radar's signal and disable the system. Always clean the bumper corners before assuming the sensor has failed.
Known Issues, TSBs, and Recalls for the 2025-2026 Acura ADX
As a new model, there are no widespread known issues, recalls, or Technical Service Bulletins (TSBs) specifically for the ADAS cameras or radar sensors on the 2025-2026 Acura ADX at this time. Early TSBs for the ADX have addressed initial quality information and telematics control unit updates. No recalls related to these specific ADAS components have been issued by the NHTSA. Owners should check for updates periodically as the vehicle ages.
Buying a Used ADAS Component for Your ADX
Purchasing a used ADAS camera or radar sensor can be a cost-effective alternative to a new part, but careful inspection is crucial.
- Verify the Part Number: This is the most important step. The part number on the replacement unit MUST exactly match the one on your original part. Even a single digit difference can mean incompatibility.
- Physical Inspection (Camera): Examine the lens for any scratches, chips, or cloudiness. Check the housing for cracks and ensure all connector pins are straight and free of corrosion.
- Physical Inspection (Radar): Inspect the plastic housing for any cracks, deep gouges, or signs of impact. Ensure the electrical connector is clean and undamaged. Damage to the housing can misalign the internal radar components, rendering it useless even if it looks functional.
- Source Matters: Buy from a reputable recycler that can provide the VIN of the donor vehicle. This helps ensure the part is correct for your trim level and features.
- Why Used OEM is Better: For ADAS components, using a genuine recycled OEM part is highly recommended over a new aftermarket part. The vehicle's safety systems are precisely calibrated to the exact specifications of the original Acura parts. Aftermarket sensors or cameras may not meet these strict tolerances, potentially leading to calibration failure or unreliable performance.
Warning: Any replacement of a forward camera or rear radar sensor requires professional ADAS calibration. This is not an optional step.
Installation and ADAS Calibration: Not a DIY Job
Physically replacing an ADAS camera or radar sensor is often straightforward, but the critical final step is calibration. This process tells the vehicle's computer the exact position and aiming angle of the new component, which is essential for the safety systems to work correctly.
- What is Calibration? A technician uses specialized targets placed at precise distances and angles from the vehicle, along with a diagnostic scan tool, to align the sensor's view with the vehicle's centerline.
- Why is it Required? Even a tiny misalignment of a fraction of a degree can cause the system to misjudge distances and angles, potentially disabling the feature or causing it to react incorrectly in a critical situation. A windshield replacement also requires camera recalibration.
- Who Can Perform It? This must be done by an Acura dealership or a qualified independent shop with the proper ADAS calibration equipment. It is not a do-it-yourself procedure.
Cost Comparison
Prices for ADAS components are high, and the mandatory calibration adds significant labor cost.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Forward Camera (8S103-3BH-A02) | $650 - $970 |
| New OEM Rear Radar Sensor (8S411-3BH-A01) | $250 - $400 (estimate based on similar models) |
| Used OEM Component | $100 - $300 (estimate, depending on availability) |
| Shop Labor (Installation) | $100 - $200 |
| Shop Labor (ADAS Calibration) | $300 - $600 |
Frequently Asked Questions (FAQ)
Can I install a used camera or radar sensor myself to save money?
While you might be able to physically install the part, you cannot perform the required ADAS calibration at home. The vehicle's safety systems will not function correctly and may show error messages until the calibration is performed by a qualified shop with specialized equipment.
Why did my ADAS sensor fail? There was no accident.
Besides collision damage, failures can be caused by internal electronic faults, water intrusion into the sensor housing, or damage to the wiring harness. For forward cameras, extreme heat has also been known to cause malfunctions in some vehicles.
The blind spot warning light is always on. Is the sensor bad?
Not necessarily. First, thoroughly clean the rear bumper corners, as dirt or debris can block the radar signal. If the light remains on after cleaning and restarting the car, a diagnostic scan is needed to check for fault codes.
Does a used ADAS part need to be reprogrammed?
Generally, these components do not require software programming to the vehicle's VIN, but they always require positional ADAS calibration to function correctly and safely.
