Vehicle warning signs

Hello my readers, it is Monday… Sure we know right? Just trynna shake some tables. Now, Modern cars are filled with electronics and packed with sensors to monitor both how your vehicle is behaving and to make our motoring life easier. But when something does go wrong, it can be a difficult task trying to work out exactly what that warning light flashing away on your dashboard is trying to tell you. It’s important to know what the car dashboard warning lights actually means,  because sometimes they can prevent your car from breaking down , potentially saving you from an expensive repair bill and making  you stay safer on the road.

Firstly, let’s talk about the
Warning lights which may vary in color and in order to indicate the seriousness of a mechanical or system problem. 

  • A red warning light indicates either a potentially serious problem or safety issue, which should be attended to immediately by a professional. However, a red light might also serve as a reminder to the driver about service maintenance.
  • When a yellow or orange light activates, it’s usually a signal that a component needs servicing or repair. If the light flashes, it’s important to contact a repair shop or dealership.
  • Green and/or blue dashboard lights only serve to let the driver know that a system is active and operating.

And second, we also have

Warning lights of a more serious nature:

  • Brake warning light:

Usually in red text, indicates a serious problem with the your brakes (main or emergency brakes).

  • Temperature warning light:

If the symbol is red, it indicates your engine has overheated. A blue light means the coolant temperature is too low. Red and blue blinking means there is an electrical wiring malfunction.

Now let’s all look at the other vehicle warning symbols;        

Battery charging system warning light:

means either a bad battery or a failing alternator. You should see your battery charge warning light when you first turn your car on, but if it doesn’t go out a few seconds after the engine starts, there could be a problem with your car’s electrical system. This could be to do with a faulty alternator, faulty battery, a bad connection or damaged cabling somewhere in the engine bay. If your car isn’t charging its battery when moving (the job of the alternator), then you could eventually run out of electrical power and grind to a halt.

At worst, the light could be on due to an alternator drive belt braking. Other systems also use this belt – such as the engine coolant pump, or power steering – so the affects of a failure here could be compounded.

Oil Pressure Warning:

If this light stays lit, it indicates loss of oil pressure. Immediately check oil level and pressure.     

  Service Vehicle Soon:

Typically indicates a lighting or other electrical problem that is controlled by the BCM (body control module). Check all lights (head lights, turn signals, brake lights, and hazard lights). This symbol may also be used to warn driver of a traction control problem, or a communication problem between modules.

Airbag Fault:

If these light stays illuminated after starting, it indicates that the vehicle has found a fault in the airbag system and the computer has set a code. Professional repair of the supplemental restraint system is highly recommended.

Door Ajar:

Indicates that a door (including hood and trunk) is not closed. Open and close all doors, including hood and trunk. If vehicle is left in this condition overnight it can drain the battery.

Power steering / EPAS warning light

If your car’s power steering warning light – often known as the “EPAS light” – is illuminated, it means there could be something wrong with the steering system.

Now as stated above “warning signs on a vehicles dashboard and what they mean” well it looks common, but as common as it is, I bet, most of us who read through this, do not even know how to come about this when these signs pops up on your vehicles dashboard. I found out that most drivers do not pay attention to their vehicle’s dashboard warning signs.  Even myself, am a victim of this, so I decided to come up with this  topic , so as to enlighten others there who are just like me, #smiles#.

Nevertheless, Your dashboard may be different and the symbols may have altered designs or indicate slightly different things, so be sure to consult your owner’s manual. Some of these lights could portend a serious malfunction. Don’t ignore them. When in doubt, have a professional check it out… See you guys next time, LOVE YOU ALL AND DO HAVE A GREAT WEEK AHEAD!!!!!!
