You just changed your Honda CRV’s battery and suddenly the cruise control stopped working. Sounds familiar? You’re not alone. Many CRV owners face this exact issue after a battery replacement. The good news is, there’s usually a simple fix.
In this article, you’ll learn how to get your cruise control working again, step by step. The real answer often comes down to resetting systems, checking fuses, or dealing with sensor or software issues. Follow along and you’ll likely fix this problem on your own at home.
Check for Warning Lights on the Dashboard
After changing the battery, one of the first things you should do is look at your dashboard. Many Honda CRV owners notice that right after the battery is replaced, lights like the ABS, VSA, or TPMS come on.
If you see any of these lights, your cruise control might not work until those issues are cleared. Cruise control often depends on other systems like braking and stability control to function safely.
When your CRV battery is removed or goes dead, the vehicle’s onboard computer might lose some memory. That means your car may need to relearn or recheck some systems. When the computer thinks something isn’t working properly, it might turn off features like cruise control to keep you safe.
For example, if your TPMS (Tire Pressure Monitoring System) light is on because the tire sensors haven’t reset yet, the cruise control may not work. The same thing can happen if the VSA (Vehicle Stability Assist) or ABS (Anti-lock Braking System) light is on. All these features are linked to each other in modern vehicles.
It’s a good idea to drive your car for a little while after replacing the battery. Sometimes, the system resets itself after a few miles. If the lights turn off on their own, that’s a good sign, and the cruise control might start working again.
If the lights stay on, you may need to use an OBD-II scanner to check the codes or reset the computer. Many auto parts stores offer free code scanning if you don’t have a scanner.
Another simple check is to make sure you didn’t accidentally bump any buttons. Some CRVs have a button to turn off the cruise control system. If it’s off, the cruise control won’t respond at all.
- Look at dashboard lights after changing battery
- TPMS, ABS, or VSA lights can stop cruise control from working
- Drive a few miles to allow the system to reset
- Use a scanner to check for error codes if lights stay on
- Check cruise control ON/OFF switch
Reset the Electronic Control Unit (ECU)
When your CRV gets a new battery, the ECU (Electronic Control Unit) might lose saved data. This can affect how the cruise control works. The ECU controls many systems in your car, including the engine and safety systems. If it gets confused after the battery change, it might disable cruise control until everything is working right again.
You can try resetting the ECU to fix this issue. Start by turning the ignition key to the ON position without starting the engine. Let it stay ON for about 2 minutes. Then turn it OFF. Do this two or three times. Sometimes this is enough to help the car relearn what it needs to do.
If that doesn’t work, you can try disconnecting the battery again. Remove the negative cable and wait 15 minutes before connecting it back. This gives the car’s brain a fresh start. But be careful — this will also reset your radio, clock, and saved settings.
Some CRV models need a full system re-learn after a battery change. This includes letting the engine idle for a few minutes, turning on the A/C, and then driving at different speeds. All of this helps the car learn how it should behave with the new battery.
Sometimes you need a scan tool that supports Honda systems to reset the ECU completely. If you don’t have one, an auto repair shop can do this for you.
- ECU may lose memory after battery change
- Try cycling the ignition ON and OFF
- Disconnect and reconnect battery again to hard reset ECU
- Let car idle and drive it slowly to help it relearn settings
- Use a scan tool if needed for full ECU reset
Inspect Brake Pedal Switch and Sensor
One of the most common reasons cruise control won’t work is because of the brake pedal switch. This small switch tells the car when you press the brake. If it’s stuck or misaligned after a battery change, it could keep cruise control from turning on.
Sometimes while changing the battery, wires or sensors can get bumped or shaken loose. If the brake switch isn’t working right, the car will think you are pressing the brake pedal all the time, even when you’re not. And if that happens, cruise control will shut off or never turn on.
To check this, gently press your brake pedal and see if your brake lights come on. If they don’t, or if they stay on even when you’re not pressing the pedal, the switch might be bad or out of place. You can usually find the switch under the dashboard near the top of the brake pedal.
Make sure it clicks when you press the pedal. You can also test the switch with a multimeter if you know how to use one. Replacing it is usually cheap and easy, and it could solve your cruise control problem fast.
Another thing to check is if the sensor is dirty or dusty. Use a dry cloth or a can of air to clean around the brake pedal area. Make sure no debris is stopping the switch from working properly.
- Cruise control won’t work if brake pedal switch is faulty
- Check brake lights when pressing pedal
- Make sure switch is not stuck or loose
- Clean around the brake pedal area
- Replace switch if needed (easy and low-cost)
Verify the Cruise Control System Is Not Disabled
Sometimes, cruise control can be turned off by mistake. There’s often a small button or switch labeled ‘CRUISE’ on the dashboard or steering wheel. After a battery change, this setting can be turned off by default. If it’s not activated, the cruise control won’t work even if everything else is fine.
First, look for a button with a small speedometer icon or the word CRUISE. Press it and watch the dashboard. You should see a green light or a cruise control icon turn on. That means the system is ready.
Then drive your CRV and reach a steady speed. Press the SET button, usually found on the steering wheel. If everything is working right, your speed will lock in, and the car will keep moving at that pace.
If nothing happens, check the owner’s manual to find the exact location of all cruise control buttons. Some CRV models have more than one switch that needs to be activated.
You should also check the vehicle’s fuse box. Sometimes, a fuse related to cruise control can blow during the battery change. Find the fuse box, usually under the dashboard or in the engine bay. Look for a fuse labeled CRUISE or something similar. Replace it if it’s blown.
- Look for CRUISE button and make sure it’s ON
- A green light or icon should appear on the dash
- Press SET while driving at steady speed
- Check the fuse related to cruise control
- Use owner’s manual to locate all switches
Scan for Error Codes and Clear Them
After a battery change, your Honda CRV may have stored error codes in its computer. These codes can stop systems like cruise control from working. You won’t always see a warning light for every error, so it’s smart to scan the vehicle even if everything looks normal.
Use an OBD-II scanner to read the codes. Plug it into the port under the dashboard. Turn the ignition on and let it read your vehicle’s computer. If you see any codes related to the throttle, brake switch, or cruise system, write them down.
Some scanners can clear these codes too. If yours does, try clearing all stored codes and then turn off the car. Start it again and see if cruise control now works.
You can also take your car to an auto parts store. Many places like AutoZone will scan it for free. Just ask for a diagnostic scan and tell them about the cruise control issue.
Clearing the codes may allow the cruise control to work again, especially if the problem was just a temporary glitch caused during the battery replacement.
- Cruise control might stop if error codes are stored
- Use an OBD-II scanner to check for codes
- Look for codes related to throttle or brake systems
- Clear all codes if possible
- Many auto stores will do a free scan
Test the Throttle and Speed Sensor
Cruise control depends on the throttle and speed sensor to hold a steady pace. After a battery change, the throttle position sensor or vehicle speed sensor might not sync correctly. If either one is not working right, the cruise system will shut off.
The throttle sensor tells the car how much gas you’re giving. If it’s dirty or out of sync, cruise control can’t keep speed. The speed sensor tells the ECU how fast the car is going. If it fails, the ECU might think the car is stopped or going too fast, so it shuts off cruise control.
To test the throttle, you can turn on the car and press the gas pedal gently. If the engine responds in a weird or delayed way, the sensor might be off. A scan tool can check the sensor readings in real time.
If your speedometer is working fine, your speed sensor is likely okay. But if it jumps around or doesn’t move at all, that sensor might be the issue.
Sometimes a throttle body cleaning is all that’s needed. Remove the air intake and gently clean the throttle with a soft cloth and throttle cleaner spray. Be careful not to damage the sensors inside.
- Throttle and speed sensor are needed for cruise control
- A dirty throttle sensor can cause problems
- Speed sensor must show correct speed to ECU
- Clean the throttle body if needed
- Use scanner to test both sensor readings

Frequently Asked Questions (FAQs)
Is it normal for cruise control to stop after battery change?
Yes, it’s pretty common. When you replace your battery, the car’s systems may reset. That can confuse the ECU or turn off some settings like cruise control. Sometimes lights like ABS or TPMS come on, and the cruise stops working because those systems are linked. Usually, driving the car for a little while or resetting the ECU will solve the issue.
Can a bad brake switch stop cruise control?
Yes, it can. The brake switch tells the car when you’re pressing the brake. If the switch is broken, stuck, or loose, the car might think you are braking all the time. That will stop cruise control from turning on or staying on. Replacing or adjusting the switch usually solves this easily and quickly.
Do I need to reprogram my CRV after a battery change?
Not always, but sometimes yes. The car may need to relearn idle speed, throttle response, and other settings. This can be done by letting the car idle, using the A/C, and driving normally. Some CRVs might also need a special scan tool to reset certain systems. If things don’t work right after a few drives, reprogramming might help.
Is it safe to drive if cruise control is not working?
Yes, your car is still safe to drive. Cruise control is a comfort feature, not a safety one. But if cruise stopped working due to a bigger problem like a brake or throttle sensor, then that issue could be more serious. It’s best to get it checked just to be sure everything is okay.
Can I fix cruise control without tools?
Yes, many times you can. Checking for warning lights, pressing the right buttons, or driving the car a bit after changing the battery can fix the problem. You may not need special tools. But for things like reading error codes or testing sensors, a basic scanner or simple tools might help.
Do I need to visit a mechanic for cruise control repair?
Not always. If you follow the steps in this article, you might fix the issue yourself. But if warning lights stay on, or if nothing works after checking switches and sensors, then it’s a good idea to let a mechanic check your car. Some problems are deeper and need professional tools.
Is it expensive to fix cruise control?
Usually no. Many problems are small like a loose switch, a dirty sensor, or a blown fuse. These are cheap to fix or even free if you do it yourself. Only in rare cases, if a major part fails, you may need to spend more. But most of the time, it’s low cost.
Can error codes stop cruise control from working?
Yes. If the car’s computer sees a problem, it might stop cruise control to keep you safe. These codes might not always turn on a warning light, but they still block cruise from working. Using a scan tool to read and clear these codes often brings the system back to life.
