Whether you’re a seasoned car owner or a first-time battery changer, learning how to properly reset your 2019 Honda CR-V after a battery swap can save time and avoid frustration. The process involves a few key steps that reestablish communication between your vehicle’s systems and the new battery, allowing your CR-V to operate as intended. In the sections ahead,
Resetting the Clock and Radio Settings
After replacing the battery in your 2019 Honda CR-V, the clock and radio presets will typically be erased. To restore these settings, you need to manually reset them.
To reset the clock:
- Turn on the ignition without starting the engine.
- Locate the clock adjustment buttons on the dashboard or infotainment screen.
- Use the hour and minute buttons to set the correct time.
- Confirm the time setting by pressing the clock or set button, if applicable.
For the radio presets:
- Turn on the radio and tune to the desired station.
- Press and hold one of the preset buttons (usually numbered 1 through 6) until you hear a beep or see the station number flash on the screen.
- Repeat for all your preferred stations.
This process ensures your radio and clock function correctly and are tailored to your preferences.
Reinitializing the Power Window and Sunroof
The power windows and sunroof on the 2019 Honda CR-V may lose their auto-up and auto-down functions after a battery replacement. To restore these features, a reinitialization procedure is necessary.
To recalibrate the power windows:
- Turn the ignition to the ON position.
- Close the window completely by pulling the switch up until the window is fully closed.
- Continue holding the switch up for about 2 seconds after the window is closed.
- Lower the window completely by pressing the switch down.
- Hold the switch down for about 2 seconds after the window is fully lowered.
Repeat this for each window that needs recalibration.
For the sunroof:
- Open the sunroof fully using the switch.
- Hold the switch in the open position for about 2 seconds after it stops moving.
- Close the sunroof fully.
- Hold the switch in the close position for about 2 seconds after it stops moving.
This process re-teaches the vehicle’s control module the limits of the window and sunroof operation, restoring automatic functions.
Resetting the Tire Pressure Monitoring System (TPMS)
Battery replacement can cause the TPMS to lose calibration, resulting in warning lights appearing on the dashboard. To reset the TPMS on a 2019 Honda CR-V:
- Ensure all tires are inflated to the manufacturer’s recommended pressure.
- Turn the ignition to the ON position without starting the engine.
- Locate the TPMS reset button, often found under the steering wheel or near the driver’s side fuse box.
- Press and hold the TPMS reset button until the TPMS indicator light blinks twice, then release the button.
- Start the vehicle and wait for several minutes to allow the system to recalibrate.
If the light remains on, verify tire pressures again or consult a technician.
Reprogramming the Remote Key Fob
Replacing the battery in the vehicle may sometimes require reprogramming the remote key fob to ensure proper communication with the car’s security system.
To reprogram the key fob:
- Sit inside the vehicle and close all doors.
- Insert the key into the ignition and turn it to the ON position, then back to OFF. Repeat this cycle three times within 10 seconds, ending with the key in the ON position.
- Press the lock button on the key fob. The door locks should cycle to confirm programming mode.
- Press any button on the key fob to program it. The locks will cycle again to confirm successful programming.
- Turn the ignition to OFF and remove the key.
- Test the remote functions to verify proper operation.
If you have multiple key fobs, you may need to program them all during this sequence.
Additional Systems That May Require Reset
After a battery change, some other vehicle systems might require attention or resetting to function optimally:
| System | Reset Method | Notes |
|---|---|---|
| Engine Idle Relearn | Start engine and allow it to idle for 10 minutes | Helps stabilize idle speed and emissions controls |
| Automatic Transmission Adaptive Learning | Drive vehicle normally for 10-15 minutes | Transmission control module relearns shift patterns |
| Navigation System | Verify system settings and perform software update if needed | Battery change may erase saved destinations |
| Automatic Climate Control | Turn on and set desired temperature | System recalibrates sensors and settings |
These resets can usually be performed without professional tools, but if any system behaves abnormally after a battery change, consulting the vehicle’s manual or a certified technician is recommended.
Steps to Reset the 2019 Honda CRV After a Battery Change
After replacing the battery in your 2019 Honda CRV, certain systems and settings may require resetting to restore normal functionality. The following steps cover key resets such as the ECU, clock, and power windows.

- Turn the ignition to the ON position.
- Access the infotainment system menu and select the clock or settings option.
- Set the correct time using the touchscreen or physical buttons.
- Reprogram radio presets and any customized audio settings as needed.
Reinitializing Power Windows
Power windows may lose their automatic one-touch function after battery disconnection and require reinitialization.
- Turn the ignition switch to the ON position.
- Fully open the window by pressing the window switch down and holding it until the window is completely open.
- Immediately pull the window switch up and hold it until the window is completely closed.
- Repeat this process for each window that has the auto-up/down feature.
| System | Reset Method | Estimated Time | Notes |
|---|---|---|---|
| ECU | Ignition ON 3-5 min; idle engine | 10-15 minutes | Clears ECU memory, may require OBD-II scanner for codes |
| Clock & Infotainment | Manual reset via system menu | 5 minutes | Resets time and radio presets |
