Warning lights on your semi-truck are there to warn of a problem. Understanding what those semi-truck warning lights mean and when immediate repairs are needed will help keep your vehicle and drivers safe.
As vehicles and technology advance to be more efficient and secure, there are more warning lights to recognize. While models and lights may vary depending on the vehicle, the list below covers a general overview of serious warnings:
The engine has more than one warning light. Most vehicles will have at least three lights, each meaning a different issue. Anytime a light goes on, always address the problem right away. You might need to bring the vehicle in for heavy truck diagnostics.
Warning/Check: This warning light means the engine has run a self-check and found something wrong. Depending on what the issue is, another light may also pop on telling you the specific problem. If not, a professional will need to look and find the issue manually and handle heavy truck repair.
Oil Pressure and Level: If the oil pressure or level light goes on, it’s a serious problem you need to address right away. Oil keeps the engine running smoothly, so oil trouble could cause complete engine seizure and failure. It may be that oil pressure is too low, and a simple top-up will fix the issue. If not, poor oil quality may be causing damage and wear to the engine, which means an oil change is in order.
Voltage and Battery Warning
The battery semi-truck warning lights will come on either to indicate poor charging or an electrical issue. As with oil, battery troubles can lead to big problems and costly repairs if not addressed quickly. Either the battery simply isn’t charging correctly, or it’s about to fail. Another cause could be the battery itself is damaged or faulty and potentially causing more damage around it by leaking acid. Always pull over and check the battery or call for help as needed.
Brakes and Tire Pressure
While these will come on as two different lights, both issues go hand-in-hand.
Brake Warning: When brake pressure is faulty, it affects how well the vehicle can brake and within what distance. Like engine warning lights, brake pressure should always be looked at immediately before continuing any driving. Failing to do so will put the driver and other vehicles on the road at risk.
Tire Pressure: Tires play a role in how well your vehicle can handle braking, turning, and general driving. Low pressure means the tires aren’t in proper contact with the road, and that lack of grip affects control. It also can use up more fuel as a result, or if there is damage to the tire itself, it risks a tire blowout. Stopping to check the problem will quickly solve the issue and let you know if you need professional repairs or an air pressure top-up.
