Electrical Diagnostics & Repair
Your Vehicle’s Electrical System
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 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 its early stages, before a major problem occurs. Simply ignoring these lights can often result in further damage to other components on your vehicle that could have been easily avoided.

Our Specialists at Your Service
Electrical system problems can be difficult to diagnose properly, especially in today’s vehicles. Without the correct electrical diagnostic tools to properly diagnose vehicles, along with highly skilled technicians, diagnosing electrical issues can be nearly impossible.
A Plus Transmission & Auto Repair has been diagnosing electrical systems for over 30 years and has developed a solid team of extraordinarily skilled technicians who know electrical systems inside and out.
Our ASE Master Certified Technicians take great pride in being the industry-leading experts when it comes to electrical system diagnosis and will do whatever it takes to properly diagnose your vehicle’s electrical issues.
Industry Leading Diagnostic Professionals
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 emissions.
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 it’s too late! Have the professionals at A Plus scan your vehicle so you can determine what needs attention.
