The important "Car Warning Lights"

The important "Car Warning Lights," these symbols are automatic alerts when the car's sensor detects a malfunction in the system.

For a simple and detailed understanding, I would like to divide the visual warning and monitoring light groups into different systems:

1.Engine and Power Control Group (Engine & Powertrain)

EPC (Electronic Power Control): * Meaning: Electronic Engine Power Control Warning Lights usually associated with Throttle Body or Throttle System

Inspection: If this light freezes while driving, the car may not accelerate or enter "Limp Mode" (speed limit mode for safety). The car should be brought into the garage to use the OBD scanner. Instantly check the malfunction code.

Engine Light (Engine Light / Check Engine):

Meaning: There is a problem in the engine system, ignition system, or exhaust system.

Verification: In the image, the Engine Failure / Problem replacement by OBD means that the OBD Scanner must be plugged into the port under the steering wheel to read which sensors are malfunctioning (e.g. blind spark plugs, exhaust sensors).

Engine Temperature Warning Light:

Meaning: The thermometer symbol dipped in water means the engine is overheated.

Inspection: Very dangerous! If this light is red, immediately find a safe parking space, extinguish the engine, and do not open the radiator lid when it is hot. Wait for the machine to cool down and check the coolant level and leaks.

2.Braking & Traction Control

ABS Lighting (Anti-Lock Braking System):

Meaning: The anti-lock system is dead while sudden braking is in trouble.

Inspection: The ordinary braking system is still working, but the anti-lock system will not work if emergency braking occurs. Brake oil level should be checked, or the ABS sensors installed on all 4 hubs may be dirty or broken.

Balance Control Light (Traction Control / ESP / Staggering Car Shaped Symbol):

Meaning: Free spinning wheel protection and skid

Verification: If this light flashes while raining or slipway, it indicates that the system is working to help prop up the car (this is common). But if the light is stuck, it indicates that the traction control system is off or there is a problem, the wheel speed sensor system must be checked.

3.Steering, Safety and Rubber Group (Steering, Safety & Tires)

Steering wheel shaped lights with exclamation marks (Power-Hidráulica / Steering Fault):

Meaning: Power steering system has problems (may be hydraulic power as pictured, or EPS electric power)

Inspection: The steering wheel will be noticeably heavier, making it difficult to turn. The power steering oil level should be checked (if available) or the steering fuse system and electric motor.

Low Tire Pressure Warning Light (TPMS):

Meaning: A tire cross-section symbol with an exclamation mark (Pressión Baja de Neumáticos) means there are one or several wheels where the tire wind is too weak.

Inspection: Park the car in a safe place and use the tire wind gauge, check all wheels. If a wheel is found with abnormal wind drop, detect a leak or nail, then inflate the tire to the size of the specified standard next to the car door.

Airbag Warning Light (Airbag Failure):

Meaning: The airbag system or seat belt austerity system is in error.

Inspection: If there is an accident, the airbag may not work. The car should be brought into the service center to check the wiring system, crash sensor or airback control box. 💡 Additional instructions to observe the color of the warning light: green / blue: the system is working normally (e.g. turn signal, dimmer light). Yellow / orange: It is an alert / surveillance. Some systems are malfunctioning, but the car is still driving enough to be taken to the garage inspection (do not neglect). Red: Danger and Urgent! The critical system has problems (high heat, low engine oil pressure, main braking system), the car should be stopped immediately when safe to prevent severe damage or accidents.
