If your seatbelt warning light is on even though the seatbelts are fastened, then you are safe to continue driving as long as the seatbelts are secure. However, this could indicate a fault with the seatbelt system, so it`s important to take your car for a diagnostics test to determine and fix the problem.
The safety belt Warning Light is located on the instrument panel. This light illuminates when one of the front occupants does not have their seat belt securely fastened. The light is also accompanied by a chime. When the seat belt is buckled, the light and chime will turn off.
The seat belt light flashing when it`s buckled may be due to a faulty buckle. But it can also be due to normal wear and tear, food crumbs, or other debris stuck in the buckle slot that can lead to sensor issues. In any case, don`t ignore it. First, check that the seat belt is actually fastened.
If this lamp lights up or flashes there is a fault in the airbag or seatbelt system. Drive carefully to an authorised repairer without delay and have the fault rectified. Have the fault in the airbag and seat belt system examined without delay; otherwise the system may fail to trigger in an accident.
What are they? Seat belt reminders are intelligent, visual and audible devices that detect whether seat belts are in use in various seating positions and give out increasingly urgent warning signals until the belts are used.
the srs warning light on the dashboard usually looks like a side view of a person sitting in a seat with a seat belt on, with a large circle (the airbag) in front of the person. it will normally light up briefly each time you start your vehicle, and then go off.
In most cases, the seat belt light will stay on when the seat belt sensor is damaged, or the housing where the buckle is inserted is damaged and needs to be replaced. With the ABS light, this could be an indication of a damaged ABS module, individual wheel sensors or electrical harness failure.
Even though seat belts are your best protection in a car accident, they can fail you. Defective and poorly designed seat belts can lead to severe and deadly injuries. The impact of these injuries can be devastating for the injured person and their family.
Faulty Sensors

These include sensors in the seats, seat belts, on the body, etc. Even if one of these sensors malfunctions, the airbag light will turn on. This is one of the most common reasons for the light showing up on the dashboard.

The bottom line is that, when your airbag light comes on, it`s vital that you don`t drive any further and have your car checked by a mechanic as soon as possible. Until the problem is diagnosed and fixed, your airbags will not deploy.
A seat belt, also known as a safety belt or spelled seatbelt, is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop.
Green or blue lights simply let you know that a system is on or operating. Orange/yellow warning lights generally signify that your vehicle needs to be serviced or repaired soon. These warnings are less urgent than if you have a red and/or flashing light. A red light means that you should take action immediately!
The sensor detects whether the seat belt buckle is latched or unlatched, allowing the passenger safety system to determine the optimum airbag deployment. It is also used as an input to the electronic park brake and the unbuckled warning system. The sensor is in a normally open position.
Alarmingly, it is not uncommon for seat belts to fail. According to the NHTSA, approximately 3 million injuries and 40 thousand fatalities are reported each year from seat belts that fail to perform as expected during motor vehicle collisions.
The seat belt not on light warns you when it senses an important safety issue: your seat belt isn`t securely fastened.
When the gas is ignited, the pressure pushes the piston up to rotate the retractor. The idea of a pretensioner is to tighten up any slack in the belt webbing in the event of a crash.
The use of seat belts is shown to cause a specific pattern of internal injuries. Skin bruise corresponding to the site of the seat belt is known as the “seat belt mark” (SBM) sign and is associated with a high incidence of significant organ injuries.
Seat Belt Pretensioners Aren`t Working

In the event of a crash, modern seatbelts feature pretensioners that help to keep occupants firmly pressed into the seat, to reduce the chance of injury. If a problem is detected with one of the pretensioners, this can actually trigger the airbag light.

From the symptoms you describe, the problem could be as simple as the seatbelt switch located in the seatbelt buckle at your right hip or its harness connector under the seat. Or it could be a more serious issue with the SDM (sensing and diagnostic module) or IPC (instrument panel cluster).
If your car`s seat belt reminder light is on, you or a passenger have failed to fasten your seatbelts after the engine has started, or a seat belt has been unfastened while the car is traveling at least 15 mph.
If the seat belt light stays on, possibly along with an annoying warning chime even after you have securely buckled the belt, the circuit is remaining open keeping the warning system active. You may need to seek assistance from a professional (and expensive) vehicle engineer in order to diagnose and repair the fault.

ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights).
