Honda Civic Lights Won’t Turn Off (Brake/Airbag/Parking/etc.)

Although the Honda Civic is a good-quality locomotive machine, it can be defective just like any other type of car. If your Civic’s lights keep flashing or won’t turn off when you turn the light switch, you’re probably worried about running the battery into the ground. There are several solutions for this problem, all of which you’ll learn today.

A common reason for Honda Civic lights not turning off is a malfunctioning headlight switch. If the switch is stuck or faulty, it can cause the lights to stay on. Replacing or repairing the headlight switch is often the solution to this problem.

Another possible cause is a problem with the car’s body control module (BCM). The BCM controls various electrical systems in the car, including the lights. If it malfunctions, it can cause the lights to stay on. Resetting the BCM by disconnecting the car’s battery for a few minutes might resolve the issue. If not, professional diagnostic and repair may be required.

Faulty door sensors can also lead to lights not turning off, as the car may think a door is still open. Checking and cleaning the door sensors to ensure they are not blocked or damaged can often solve the problem. If cleaning doesn’t work, the sensor might need to be replaced.

Throughout this article, you’ll also learn the following details about why your Honda Civic’s lights won’t turn off:

  • Several solutions for every reason the lights seem to stay on after you turn off the car
  • Primary causes that make your Civic’s lights stay on longer than they should
  • Tips to find the source of the problem as quickly as possible

If your Honda Civic lights won’t turn off, it may be having a bad light relay. To ascertain this, find a relay in any part of the car with an identical part number. Insert the relay where the supposed faulty one was. If the lights turn off immediately, the problem evidently lies with the relay. You will need to purchase another relay to replace the faulty one.

If the lights remain on after inserting another relay, then the light’s switch may be malfunctioning. Remove the switch and check to see whether there is any physical damage. If there are burns or a broken part, you will have to replace the switch.

It is important to note that leaving your lights on when you are beside the road is illegal, as it dazzles other drivers. This can also get you arrested, so ensure that your lights not turning off gets fixed as soon as possible.

Honda Civic Brake Lights Won’t Turn Off

The brake lights in a Honda Civic indicate other drivers that you’re braking; therefore, they should too. So if the brake lights won’t turn off, this could endanger not only your life and your passengers, but also those in vehicles as well as motorists behind you.

Often, many people mistake tail lights for brake lights, and vice versa. The difference is tail lights will turn on when either the headlights or parking brake is on. The brake lights will turn on when the brakes are pressed to indicate that the driver is braking.

The brake lights use the stoplight switch; hence after pushing the brake pedal, the switch completes the circuit, and the brake lights turn on. If the brake lights don’t go off, it is most likely caused by a circuit error or a faulty brake light. To confirm this, check the fuse and the brake switch located under the dashboard near the top of the cable.

Opposite the brake switch is a stopper. For the stopper to work properly, it needs to be depressed completely by the switch. If this does not happen, it indicates that the entire brake light system needs to be replaced. If the stopper is missing, try scanning the floor of the car. If you don’t find it or you find it broken, you’ll have to replace it. Remember not to loosen the pedal and make sure the new stopper completely depresses the brake light switch.

A bad electric system can also be the issue. Carefully check the electric lines to make sure that everything is working as it should.

The fuse diagram, which is drawn on the lid of the fuse box, will help you locate the fuse of the brake. Once you locate it, check if it is blown out. If it is, have it replaced or repaired.

The brake pedal may also be stuck, making the switch remain open. If there is a connection between the brake pedals and the brake switch, the brake lights remain active.

If all the above do not seem to work, your last option will be to check if the socket is dirty or corroded. The wiring may be worn out to a point where it could be making an intermittent connection that enables the lights to stay on.

Honda Civic Parking Lights Won’t Turn Off

Car parking light

The parking lights turn on when you press the brake and should turn off once you release the brake. If, after parking, you find the parking lights are still on, this indicates a problem with the system. Leaving your parking lights on for a long time drains your battery, certainly not as much as headlights do, but it is still significant.

A common reason for this could be a switch failure. To confirm, jiggle the handle after it is down. If the light goes off, then it is safe to say that the switch is the one to blame. The switch should be replaced to restore the normal functioning of the parking lights.

If the brake handle has not been lowered completely, this makes the parking lights stay on. Ensure the handle has been put down and the parking brake disengaged because any parking brake pressure will cause the lights to go on.

If your Honda Civic is encountering irregular brake fluid pressure in some lines, the braking performance will be impacted, making the parking lights stay turned on. See to it that the fluid pressure in the lines is even.

Honda Civic Airbag Lights Won’t Turn Off

The airbags shield you from impact during a collision. If the airbag lights in your car stay on for a long time, there may be a faulty sensor. This can be rectified by taking the car to a mechanic so that they can reset the computer system and check the sensors, as they fail at times for no reason.

There is also a possibility that the airbag backup battery has been depleted. The car battery, just like the airbag’s light, can also drain the backup battery. After completely recharging the battery, the problem should automatically correct itself, but if it fails to, you should recharge the backup battery and reset the sensors.

The airbag module may also be wet, probably due to being parked outside during heavy rain, and rainwater got into the car. It could also be that you accidentally poured water in the car, and it reached the module. The airbag module, which is located under the passenger’s or driver’s seat, may get corroded due to the water, hindering the module’s performance.

The airbag clock spring helps maintain the continuity between the airbag on the driver’s side and the car’s electrical wiring. They also coil when the steering wheel turns. These springs may be damaged, hence making the airbag’s lights faulty.

It is also possible for the airbag clock springs to wear out over time, causing a weak or bad connection. In such a case, we recommend taking the car to a mechanic as this situation can be technical and requires a professional.

If you have taken all the precautions above and have made sure that your car has no related issue, take the airbag’s Engine Control Unit (ECU), remove it, and send it to the company that deals with it. The company will clear and reset it for you. You can also take the car to a mechanic so they can determine the problem thoroughly.

Honda Civic Interior Lights Won’t Turn Off

The interior lights operate through multiple switches whereby the light is controlled by a fuse that covers multiple items. When the switch refuses to turn off, try adjusting the interior light switch. This switch is responsible for controlling the brightness of the display on the dashboard. The lights can turn on if the switch is at the highest level. Reduce the switch to the lowest point to see if it will rectify the situation.

Open each door, locate the door switch, and press each switch to hear a clicking sound. The clicking sound means that the switch has been turned off. If you fail to hear a clicking sound, or you have been adjusting the button for a long time, then there is a chance the switch may be faulty and needs to be replaced or repaired.

You can also correct this problem by starting the car and allowing it to run for a short while. Then, switch it off, open and close each door, and let the lights turn off automatically. If the lights don’t go off, remove the bulb so that the battery does not get drained before taking the car to a qualified mechanic.

The mechanic will consider tracing the wiring for each switch. Each switch’s wiring should run from the door and end at the cable harness located behind the dashboard.

Honda Civic Hazard Lights Won’t Turn Off

Hazards are important in signaling a warning to other drivers that your Honda Civic is stationary. This can be as a result of being in a dangerous position on the road after an accident or if the car breaks down. The hazards mean that other drivers should stay away so that they can prevent any possible accidents.

Your hazard lights not turning off could be a result of the connector on the hazard switch coming off. The switch may be experiencing a short. Ensure a mechanic tests the control to know whether it needs to be repaired or replaced. To turn off the hazard lights, reach for the reset button located under the dash and press it.

Honda Civic Tail Lights Won’t Turn Off

Car tail lights

The brake light switch can still be engaged when the vehicle is off, leaving the brake lights on. The majority of cars usually have a stopper that disconnects the switch when the brake pedal is not moving.

The stopper is normally plastic and can shift or break, leaving the switch connected and the brake lights on. This stopper is located on top of the brake pedal, and you should ensure it is always there.

To solve this, exert pressure on the brake pedal to get access to the switch and press the button on the brake light switch. If it doesn’t work, the switch is the culprit and needs to be replaced.

You can also remove the battery. If the tail lights go off, it means that the stopper is not engaging the switch; therefore, there’s a need for it to be replaced. To temporarily fix this, you can improvise an object with the same size as the stopper by fixing it to where the stopper should be. This should keep you going up until you replace the stopper, which shouldn’t take long.

If the trailer light plugs are faulty, they are corroded or worn out. The tail lights stay on, but before you ascertain that this is the issue, ensure that the other tail lights are working perfectly.

For cars with a trailer light plug, we would recommend disconnecting the switch. If the tail lights go off, the switch is the culprit in question, as well as the light plug assembly, which needs to be replaced. In some instances, the wiring can be the problem, but changing the wiring system is not technical.

Honda Civic Dome Lights Won’t Turn Off

Dome lights in your Honda Civic, when installed properly, should turn on when a door is opened and turned off when the door is closed. If the switch is faulty, it may be the reason the dome lights won’t turn off.

The dome lights operate through multiple switches that are on each door. The main knob is on the dashboard, left of the steering wheel. Ensure you remove the bulb so that the battery will not be drained. This should last until a mechanic inspects the car.

To remove the bulb, use a screwdriver (most of them require a Phillip’s head, but some need a flathead screwdriver) to loosen the screws. Some models have a clip you can slide a flathead under; Pry it off gently, set the faceplate to the side, and unscrew the bulbs. Make sure your car is turned off when you do this process.

As silly as it might sound, you might’ve forgotten to turn them off. Many Honda Civics come with dome lights that have a switch. Check the knob to ensure it’s set to the ‘off’ position, then close the door. If they stay on, there’s likely a mechanical error.

Honda Civic Lights Blinking / Flickering

Mechanic testing car battery

Drivers use flickering lights on the road to tell other drivers that there are crashed cars, police speed traps, or to show appreciation. However, if the driver does not control this flickering of lights, then it gets annoying. It is also a sign that there is a faulty part in the lights system. Your battery might be dying, which could be caused by the alternator.

An alternator charges the battery of the car when it is at high speed. It also provides electrical power for the rest of the vehicle when it is running. Although the alternator does not require any maintenance, unlike most parts in a car, it can sometimes fail. When this happens, it needs replacement.

If the alternator isn’t supplying the proper electrical current, the battery will drain and drop the lights (which starts as a flicker, then turns them off entirely). Check your vehicle’s battery meter or test it with a multimeter when you get home. If it’s lower than 12 volts, there’s a problem.

Honda Civic Tire Pressure Light Keeps Coming On

Checking tire pressure

When a car’s tires are underinflated or overinflated, it can cause deadly accidents on the road. The car tire pressure monitoring system can either be direct by using sensors, or indirect, which means the wheel-speed sensors are part of the anti-lock braking.

In most cases, tire pressure lights coming on are mostly reported during the cold weather season. This is because the pressure in the car contracts triggers the tire pressure monitoring system, hence turning on the lights. Because it is a natural cause, there is no way to rectify it. However, when driving, the heat generated through friction will cause the temperature to rise, thereby making the lights disappear.

The tires could also be experiencing a slow leak that reduces the pressure, making the tire generate a lot of heat. The heat generated together with friction can make the tire wear out, which may lead to a potential tire blowout. To prevent this occurrence, the tire pressure lights will signal you by staying on.

If any of the above possibilities is not the specific reason, then the tire pressure monitoring system is the one at fault. There could also be a faulty pressure sensor in one of the wheels. To fix these problems, take your Honda Civic to a mechanic. Maintaining good tire pressure is vital to avoid accidents.
