The illustration below shows the warning lights that could appear on your Nissan’s instrument panel.
The majority of these warning lights pretty much go without saying. Some of these warning signs, though, need to be emphasized more clearly. Together, let’s analyze these danger lights!

Brake Warning Light
Parking Brake Indicator Light and Low Brake Fluid Warning Light are the two main purposes of the brake warning light. When the ignition is turned on while the parking brake is being applied, this parking brake indicator illuminates. Only with the ignition on and the parking brake not engaged will the Low Brake Fluid Warning illuminate. If you notice this light, check the vehicle’s brake fluid levels right once, or have a Certified Nissan Service Technician look at it.
Low Tire Pressure Warning Light
The Low Tire Pressure Warning Light further performs the duties of the TPMS Malfunction Warning Light and the Low Tire Pressure Warning Light. The pressure in your tires has to be raised if this light is on all the time while you’re driving. There is a TPMS issue if this light flashes after starting the car and stays on for a minute. In this situation, you want to schedule a Certified Nissan Service Technician inspection of the car as soon as you can.
Master Warning Light
Several different circumstances for the Master Warning Light to turn on. No Key Warning, Door/Truck Open Warning, Parking Brake Release Warning, Low Windshield-Washer Fluid Warning, Low Tire Pressure Warning, and Loose Fuel Cap Warning are all warnings that will cause this light to come on.
How can the dashboard’s brake light be reset?
First, disconnect your automobile battery’s positive cable. Then, maintain your foot firmly on the brake pedal to shut off the car’s electrical system. The core computer of the car will be reset as a result. Reconnect the cord to re-establish electricity. This should reset the light if the system doesn’t still have a problem.
Step two: You might need to replace the ABS sensor if the light returns after being reset. To do this, unhook the sensor’s wire and detach the housing from the sensor, which should be affixed to the wheel hub. Next, mount and attach a fresh sensor. It’s possible that using the aforementioned technique, you’ll still need to restart the computer.
Step Three: If the light continues to illuminate, you should utilize an ODB code reader to identify the issue because the car still thinks there is a problem that justifies the light. Take your car to a shop to have the issue identified and fixed if you don’t have an ODB code reader.
How do I turn off the brake warning light?
Almost always, when this warning light comes on, you require new brake pads. You can install a set of replacement pads yourself if you have the necessary skills. Alternatively, you might hire a pro to complete the task for you. The brake pad sensors provide a dashboard alert to appear when the brake pads start to wear.
An Engaged Parking Brake
The parking brake sensor will signal the brake warning light to switch on if the parking brake is still engaged. The parking brake on your car should be entirely disengaged to prevent this from happening in most cases.
If you keep it the way it is, you’ll be using your parking brakes all the time, which can cause your brakes to overheat and hasten the wear of your brake shoes and brake pads.
The efficiency of your braking system may be impacted by the accelerated brake fluid deterioration brought on by these elevated temperatures.
Low Brake Fluid Levels
The amount of braking fluid in the system is monitored by a sensor in the brake master cylinder. The sensor will cause the brake light to illuminate if levels are below the minimal threshold.
Low brake fluid levels can be very concerning because they may be a sign of an urgent brake fluid leak.
Worn Out Brake Pads
As the caliper pistons must extend further to make contact with the rotor, worn brake pads might also result in a drop in brake fluid level, which can also activate your brake warning light.
This sensor wire makes contact with the rotor when the brake pads get too worn, which prompts the brake light (also known as the brake pad warning light) to turn on.
Anti Lock Braking System Malfunction
A brake warning light for the antilock braking system (ABS) is present in the majority of automobiles.
Both the brake warning light and the ABS light (if it has one) may turn on in response to issues with the antilock brake system. Electrical problems and even something as simple as a dirty wheel speed sensor can be the culprits.
A 7440 bulb fits what?
Turn signal, tail light, and backup bulbs are frequently found in Hondas, Chevrolets, Scions, Volkswagens, Toyotas, and other makes and models as 7440 and 7443 bulbs!
Can I swap out my own tail light assembly?
Do It Right: In some cases, you’ll need to remove a small panel in order to gain access to the assembly’s interior. To remove the bulb socket from the assembly, turn it to the left. The old bulb will then typically just fall out of the socket. Slide the replacement bulb into the socket after adding a little bulb oil.
My brake light is on, but my brakes are functioning properly.
faulty sensors
The parking brake sensor or brake fluid measurement sensors in the brake master cylinder could malfunction, turning on the brake light. A brake repair specialist should be able to recognize the sensor that activated the light and replace it.
Why does the brake light on my dash remain on?
Don’t risk operating the vehicle if you’ve just started it and you see the brake system warning light on.
To begin with, confirm that the parking brake is fully disengaged. Some automobiles have a combined parking brake and braking system warning light. Make sure your parking brake is fully disengaged by checking it and pulling on the release lever. If the dashboard light is still on, your vehicle’s brake system may be malfunctioning and making it difficult for you to stop. Shut off the engine and make plans to have the car delivered to a reliable repair.
