Dashboard Warning Lights Explained and How to Repair Them
Modern vehicles are equipped with a slew of dashboard warning lights that act as a nearly warning system, alerting drivers to potential mechanical problems. These warning lights are intended to assist drivers in identifying problems and taking appropriate action to prevent further damage or accidents. In this post, we'll look at some typical dashboard warning lights, explain what they signify, and show you how to fix them.
Check Engine Light
One of the most well-known warning lights is the check engine light, which is commonly symbolized by an engine symbol. It denotes a problem with the engine or one of its components, such as the exhaust, fuel, or ignition systems. .When this light comes on, it's crucial to have the car checked out by a qualified mechanic who can read the onboard diagnostic system (OBD-II) codes using specialized equipment. The OBD-II codes will identify the precise problem, enabling the necessary repairs.
Battery or charging system light
The battery or charging system light, which is typically represented as a battery symbol, signals an issue with the car's electricalcharging system. It might indicate a bad alternator, a bad battery, or a loose or damaged connection. It is essential to inspect the battery terminals forcorrosion or looseness if this light illuminates. A qualified mechanic shouldalso be contacted to inspect the battery, alternator, and related parts.
Oil Pressure Warning Light
This light, which resembles an oil can, warns drivers when the oil pressure is low. It often denotes low oil levels or a broken oil pump, which, if left unattended, can cause harm to the engine. If this light comes on, stop as soon as you can in a secure area, and check the engine oillevel. It is preferable to get in touch with a mechanic for additional diagnosis and repair if the oil level is sufficient.
Tire Pressure Monitoring System (TPMS) Light
The TPMS light alerts drivers to low tire pressure in one or more tires. It is represented by an exclamation point in side a tire. For the best handling, fuel economy, and tire life, it's critical to maintain the recommended tire pressure. When this light turns on, use a tire pressure tester to check the tire pressures and then raise or lower them to the levels advised by the manufacturer. If the light stays on, a damaged tire sensor may be the cause, which calls for professional repair.
Anti-lock Braking System (ABS) warning light
The Anti-lock Braking System (ABS) warning light, which is represented by the letters "ABS" enclosed in a circle, flashes when there is a problem with the ABS system. The ABS system improves control and stability by preventing wheel lock-up while braking. If this light comes on, there may be a problem with the hydraulic pump, ABS sensors, or other connected parts. While the standard brakes will still work, it is crucial to get the ABS system checked out and fixed by a trained professional. When this light turns on, use a tire pressure tester to check the tire pressures and then raise or lower them to the levels advised by the manufacturer. If the light stays on, a damaged tire sensor may be the cause, which calls for professional repair.
Air bag warning Light
The airbag warning light, which is typically represented by a picture of a seated person with an airbag deployed, alerts the driver to a potential issue with the airbag system of the car. This device is a crucial safety component that safeguards passengers in the event of a collision. If the light stays on or flashes, the airbag system may be experiencing issues due toa bad sensor or wiring. Consult a specialist right away to identify and resolve the problem.
Keep in mind that dashboard warning lights should never be disregarded. While some lights may hint to small difficulties, others may signify serious issues that need to be addressed right away. Consult the owner's manual for your car or enlist the help of a skilled mechanic if you are unsure what a certain warning light means.
