Electrical Diagnostics & Repair

Your automobile’s electrical system is complicated and is responsible for communicating with almost every component in your vehicle. When this communication becomes interrupted or fails, it can trigger a system alert usually resulting in a check engine light, transmission light, battery light, abs light, etc. These warnings should never be ignored and can be indications of an electrical component failure, wiring problem, or a mechanical issue.  By having your vehicle’s electrical system scanned immediately when any of these warning lights pop up, there is a much better chance of catching an issue at it’s early stages, before a major problem occur.  Simply ignoring these lights can often result in further damage to other components on your vehicle that could have been easily avoided.

Check Engine Light Diagnostics

All modern vehicles are equipped with an onboard computer diagnostic system (OBDII) that constantly monitors your vehicle’s major operating systems, and most importantly, the power-train (engine and transmission). The main purpose of monitoring these systems is to ensure that the vehicle is operating efficiently, producing solid power to the wheels while maximizing fuel economy and reducing harmful emmisions. When the computer reads that any of these systems’ parameters do not fall within the acceptable range for operating the vehicle, it will display a light on the dashboard showing the driver that something is not functioning properly. Although you may not feel anything out of the ordinary, there is an issue with the vehicle and by simply overlooking the light you could be asking for much bigger problems. Don’t wait until its too late! Have the professionals at A Plus scan your vehicle so you can determine what needs attention.

Reading the codes from your car’s computer system is similar to a doctor measuring your blood pressure when you schedule a visit. High blood pressure doesn’t tell the doctor what is wrong with you, it simply lets the doctor know there is something wrong. The same is true with check engine lights. The codes tell the automotive technician there is something wrong and points them in the right direction to properly diagnose the vehicle. The experts at A Plus Transmission & Auto Repair have been diagnosing check engine light issues since before vehicles switched to the new OBDII System in 1996, so you can be confident that your vehicle will be properly diagnosed.
