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. At J.S. Automotive, we can pull the code and diagnose the problem for you. Give us a call or stop by one of our locations in Southwestern New Hampshire for our expert assistance.

Computer
Today, car manufacturers include at least one computer in motor vehicles. This computer's main function is to monitor and adjust engine and transmission operations. The computer receives input information from different sensors. The computer controls spark plugs, idle speed, and fuel injectors so as to get you the best possible car performance. Failure of the car computer will greatly affect the things it controls. To get the most out of your car's computer, have it evaluated regularly for updates and proper operation. If it is already failing, have it repaired or replaced. To have your car's computer handled by experts, visit J.S. Automotive in Southwestern New Hampshire today.

Computer Reflashing
J.S. Automotive has state-of-the-art equipment to provide computer reflashing to our customers in the Southwestern New Hampshire area. The primary reason to reflash a computer (which basically means updating or reinstalling its software) is that an update has been issued by the manufacturer. It's 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 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. Stop by one of our locations or call us to schedule an appointment!

Diagnostics
Mechanics at J.S. Automotive are able to diagnose all the electronic parts in your car. For expert diagnostics services on your car's electronic devices, visit J.S. Automotive today.

Drivability
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 case of drivability problems, you will receive a warning message on your car's dashboard. To have your car diagnosed for drivability issues, visit J.S. Automotive in Southwestern New Hampshire today. At J.S. Automotive, we have the necessary tools, training, and technology to diagnose and address your car's drivability issues.

Engine Controls
Basically, an 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 incredibly powerful technology, make sure engine controls are working properly. To check if your car's engine controls are working properly, call J.S. Automotive today.

WHAT OUR CUSTOMERS SAY

My wife's 5-yo Ford Edge developed a dead battery on Christmas day. We were able to jump start it, and drive it in to JS Auto in Grantham. Chris was kind enough to fit us in the next day, when they opened, run the full diagnostics, and install a new battery. They were fully booked that whole week, and had one person out sick, but he was able to fit us in even after the holiday. As usual, they were thorough, and did a great job. My wife and I are very appreciative of their going the extra mile to help their customers! , 12/26/2023
