Today’s cars are rolling computers, everything controlled electronically by the brain. One positive aspect of the computer brain is the warning lights on the dash that tell the driver lots of information. While some like 'door ajar' or 'washer fluid low' are easy ones to decipher, others may take the expertise of a Japanese auto shop in Roswell. These are brief explanations for the indicators that are most important. Check Engine The check engine light on many different models is a catch-all indicator of a problem. Sometimes, it's just a reminder for service while other times it may indicate a serious problem. Most often it will indicate a problem with the combustion of fuel in the engine that leads to low power. This can be because there is not enough air or fuel in the mixing chamber or that one or more spark plugs is not firing correctly. This is the one indicator light that requires a certified technician to decode the problem. Under the Hood Lights There are several lights that indicate a problem with specific areas under the hood. The check battery light can tell of poor battery connections or a battery charge that is low. The check oil light usually indicates the oil pressure is low. Low oil pressure can be a sign of a leak and should be checked out immediately. Transmission and coolant lights also indicate low fluid levels and should be checked. Many of the indicator lights for under the hood can be avoided during a routine oil change when the technician will inspect each area. Outside the Engine The other lights on the dash panel will indicate a concern with the wheels and the accompanying parts. The most often seen light is usually the low tire pressure light or the tire monitoring system light. Low tire pressure can lead to loss of control during higher speeds and braking. A tire monitoring light is often accompanied by a light for the traction control system. The traction control system will monitor the tires for slipping on icy or even wet road surfaces. This allows for better control of the vehicle and safer braking in hazardous conditions. The brake system will have an indicator to show the driver many different things, like the parking brake being set or low fluid. The ABS light will indicate a problem with the anti-lock braking system, which can be serious. There are some other lights, like the airbag light, that indicate safety features for the driver and passenger. These should be checked immediately by any local Japanes auto shop in Roswell before a tiny accident becomes a serious medical issue.
