How to reset acura parking sensor?

There isn’t a universal reset button on Acura parking sensors. In many cases, you can refresh the system with basic checks and a short power reboot. If the warning continues or the sensors don’t respond after those steps, professional recalibration or replacement may be required.


Understanding how Acura parking sensors work


Acura parking sensors are part of the vehicle’s active safety system. They use ultrasonic sensors embedded in the front and/or rear bumper to detect obstacles and relay distance information to the driver through audible beeps and dash indicators. Factors like dirt, ice, bumper damage, or a short software hiccup can cause false readings or a nonresponsive system. While some issues resolve with a simple reset, others demand dealer diagnostics or sensor replacement.


Do-it-yourself reset and troubleshooting steps


Use this checklist to diagnose common causes of non-responsive parking sensors. The steps below are designed for typical Acura models and may vary by year and trim.



  • Inspect and clean the sensors. Look for dirt, mud, ice, or snow covering the sensor faces and wipe them clean with a soft microfiber cloth. Avoid abrasive cleaners and sharp objects that could scratch the sensor surface.

  • Look for visible bumper damage or misalignment. A bumped or loose bumper can misalign sensors, triggering errors. If you notice cracks or gaps, avoid driving aggressively and seek professional inspection.

  • Check related fuses. Locate the fuse boxes (in the dash and/or engine bay) and inspect the fuses labeled Parking Assist, Parking Sensor, or similar terms. Replace any blown fuse with a fuse of the same amperage.

  • Reboot the system with a power reset. With the ignition off and the key removed (or the vehicle in accessory/ON depending on model), disconnect the negative 12V battery terminal for about 10 minutes. Reconnect, then start the engine to allow the system to reinitialize.

  • Drive to recalibrate. After reassembly, drive the car at low speed (in a safe area) and slowly move in reverse and forward for a short period to give the system time to recalibrate and recognize the sensors again. If the warning persists, proceed to professional diagnostics.

  • Check for software updates. Some Acura models can receive infotainment or body control module updates that affect sensor operation. Confirm with the owner’s manual or dealer whether a software update is available for your year/model.


The steps above are commonly recommended for modern Acura vehicles. They are intended to address minor glitches or misreads caused by dirt, temporary faults, or a brief reboot of the system. If the problem remains after these steps, you should pursue professional help.


When to seek professional help


If the sensors still fail to respond after cleaning, fuses, and a battery reset, or if you notice frequent false readings, a professional diagnostic is warranted. A trained technician can read diagnostic trouble codes from the vehicle’s computer and verify sensor alignment and wiring integrity.



  1. Have a certified technician inspect sensor alignment and mounting. Misalignment can occur from minor bumps or impacts, and realignment often resolves erroneous readings.

  2. Conduct a comprehensive electrical diagnostic. The technician will check the sensor circuits, harnesses, and the control module for faults or corrosion.

  3. Replace faulty sensors if needed. If a sensor is damaged or consistently fails tests, replacement is typically required to restore proper function.

  4. Perform system recalibration with appropriate tools. Some Acura models require specialized scan tools to re-teach the system the exact positions of the sensors after work is completed.

  5. Check for model-specific advisories. Certain recalls or service bulletins may cover parking sensor issues; the dealer can verify eligibility and perform any recommended actions.


Professional inspection provides a definitive answer on whether the issue is purely mechanical (sensor dirt, misalignment, or wiring) or software-related, and ensures the system is calibrated to the vehicle’s specifications.


What a technician will typically do


In a service visit, technicians may undertake one or more of the following: sensor cleaning and realignment, wiring tests, control module diagnostics, software calibration, and, if necessary, sensor replacement. Modern Acura vehicles can require recalibration after any bumper work or sensor replacement to ensure accurate performance.


Summary of practical steps


For most cases, start with a clean, unobstructed sensor, verify fuses, and perform a controlled power reset. If the issue persists, a dealer or qualified technician should diagnose with professional tools and, if needed, recalibrate or replace faulty components. Regular maintenance checks can prevent future false readings and help keep the system reliable.


Final takeaway


Resetting Acura parking sensors is often a matter of routine cleaning, fuse verification, and a short power reboot. Persistent problems after these steps typically require professional diagnostics and calibration to restore full functionality.


In a rapidly evolving field of vehicle safety technology, reading the owner’s manual and consulting a certified Acura technician remains the best course when sensor performance is inconsistent. Staying current with software updates and addressing bumper damage promptly can prevent future sensor faults.

  1. Turn the ignition to the "on" position (without starting the engine).
  2. Press the brake pedal.
  3. Press and hold the parking brake release switch in the release position for 3-5 seconds.
  4. Check the dashboard for any confirmation lights or messages indicating the reset was successful. 

Method 2: Perform a system reboot

  1. Locate and disconnect the negative battery terminal.
  2. Wait for at least 15 minutes to allow the system to fully discharge.
  3. Reconnect the negative battery terminal.
  4. Turn the ignition to "on" and check the EPB status. 

If the problem persists
  • Check the fuse: Look for any issues with the EPB fuse, which may be shorted or blown. 
  • Consult a professional: If the issue continues, there may be a more significant problem with the actuator or another component. It is best to have the system diagnosed and repaired by a professional mechanic or Acura dealer.
