To reset Honda Sensing, you typically reboot the system by turning Honda Sensing off and on again using the MAIN switch, or by cycling the ignition, and you should ensure the sensors and camera are clean. If warnings persist after a reboot or if a sensor has been replaced, a dealer recalibration is usually required.
Honda Sensing is a suite of driver-assistance features that relies on a forward-facing camera and radar sensors to operate. While you can often reset the system with a quick reboot, some situations—such as after windshield replacement, major sensor work, or after calibration drift—require professional recalibration. Use the steps below to reboot, clean, and troubleshoot the system, and know when to seek service.
General Reset Procedure
Use these steps to reboot the Honda Sensing system. The exact controls can vary by year and trim, but the basic approach is widely applicable.
Reboot and power cycling
- Park safely and keep the engine running, or turn the ignition to ON without starting.
- Find the MAIN switch/button for Honda Sensing (often on the left side of the steering wheel or dash) and press it to turn Honda Sensing OFF.
- Wait 2–5 seconds, then press MAIN again to turn Honda Sensing ON.
- Observe the instrument cluster for the Honda Sensing indicator to confirm it’s active, then take a short test drive to ensure proper function.
If the system remains unresponsive, perform a full power cycle: turn the engine OFF, remove the key or press the Engine Start/Stop button to stop, wait about a minute, then restart and re-enable Honda Sensing.
Running a quick reboot cures many minor glitches and resets the feature nerve center without professional help. If issues persist after this reboot, proceed to sensor cleaning and, if necessary, professional calibration.
Sensor Cleaning and Calibration
Clean sensors and the camera regularly. Dirt, snow, ice, or obstructions can trigger false alerts or disable features. After cleaning, recheck system status and perform another reboot if needed.
Cleaning techniques and calibration basics
- Clean the forward-facing camera mounted near the rearview mirror with a soft microfiber cloth and a mild glass cleaner if needed. Avoid abrasive cleaners or spraying liquid directly on the camera.
- Wipe the radar sensors behind the front grille or bumper area with a damp microfiber cloth. Do not scrub aggressively; remove any grime or debris that could block readings.
- Clear any snow, ice, or slush from the bumper area and around the camera or sensors before driving in winter conditions.
- Inspect the windshield for chips or cracks that could affect camera visibility; repair as needed to maintain calibration integrity.
- Check for aftermarket accessories (dash cams, ornamentation, or aftermarket tint near the camera) that could interfere with sensor lines of sight and remove if necessary.
Regular cleaning helps prevent false warnings and ensures more reliable sensing. If you recently replaced a windshield or performed major work near the sensors, a professional calibration may be required to restore full accuracy.
When Resetting Isn’t Enough
Some situations require professional assessment beyond a simple reboot or cleaning. Here are common signals that warrant service.
Indicators that you may need dealer intervention
- Persistent warning messages such as “Honda Sensing unavailable” or “System requires service” despite resets and cleaning.
- After windshield replacement, or major bumper/sensor work, where the camera or radar cannot be re-calibrated correctly in your vehicle.
- Unexpected or erratic behavior from ACC, LKAS, CMBS, or RDM, such as sudden braking, lane deviations, or failure to engage when conditions are suitable.
- Repeated false alerts or a failure of Honda Sensing features to engage even when road conditions warrant them.
In these cases, schedule a service appointment. The calibration procedures are typically performed with diagnostic tools and may require realignment of the camera or radar sensors by a Honda-certified technician.
Summary
Resetting Honda Sensing usually starts with a simple reboot using the MAIN switch and a quick engine ignition cycle, combined with ensuring the camera and sensors are clean and free of obstructions. If a reboot alone doesn’t restore function, cleaning the sensors and, when necessary, undergoing professional calibration are the next steps. Address any persistent warnings promptly, as improper calibration or sensor issues can affect the system’s safety performance.
