vehicle computer diagnostic services

Electronic services include check engine lights, computer systems, and engine controls.

Our electronic services include:

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. Bring your vehicle to Seymour's Garage and have us work on pulling codes to find the source of the malfunction.


Today's vehicles are far more complex than they used to be! With the addition of high-tech technical engines and components, comes a need for an expert technician. Our computer's main function is to monitor and adjust engine and transmission operations. The computer receives input information from different sensors. Your vehicle's computer controls spark plugs, idle speed, and fuel injectors to get you the best possible ride. 


Computer Re-programming or Reflashing
Seymour's Garage's state-of-the-art equipment and expert technicians can take care of all of your computer needs! The primary reason to reflash a computer (which basically means updating or reinstalling its software) is that there could be an update that has been issued by the manufacturer.  This is a very simple procedure, and there may be minor updates that the car hasn't had. The manufacturer may have tweaked the transmission-shifting algorithm or some other parameters that are not necessarily crucial but may bring slight improvements to drivability, mileage, or emissions. Since auto manufacturers are coming out with automobile updates every day, there may be a reprogram available for your vehicle. Ask one of the service advisors at Seymour's if your vehicle has any available updates.


General Diagnostics
Seymour's Garage can diagnose all the electronic parts in your car. Some customers elect to have a vehicle diagnostic done so they can make a service plan.


Drivability & Engine Controls
Drivability is the degree of smoothness and steadiness of your car's acceleration. Most modern cars are fitted with on-board computers that continuously check the readings from various sensors. In the case of drivability problems, you will receive a warning message on your car's dashboard. Seymour's Garage has the necessary tools, training, and technology to diagnose and address your car's drivability issues.

The engine control system is an on-board computer in your car. Like all computers, the engine controls are composed of hardware and software. Automotive engine control systems are responsible for regulating exhaust emissions, and providing increased fuel economy. To get the best out of your car's technology, make sure engine controls are working properly. Call Seymour's Garage at 210-341-1171.
