Vehicle Diagnostics in Southington, CT
L & S Automotive offers diagnostics alongside repair and maintenance. Our Plantsville service department helps Southington drivers take the next step when a warning light, noise, or running concern needs investigation.

When to ask about vehicle diagnostics
- A warning light remains on or returns after a repair.
- A noise or running problem is difficult to explain.
- An emissions test result needs professional review.
What the service involves
Share symptoms, when they occur, and recent repairs or battery work. A diagnostic visit investigates the complaint; stored trouble codes, when relevant, are clues for further checks. Testing depends on the vehicle and system involved.
What matters for your vehicle
A trouble code is not a complete diagnosis and does not automatically identify a part to replace. Intermittent issues may need more investigation. Confirm support for the specific concern. Stop safely and seek assistance for flashing warnings, overheating, or loss of braking.
What affects the price?
The system, access, testing required, and whether the symptom can be reproduced affect diagnostic cost. Ask what the initial evaluation covers and when further authorization is needed.
Vehicle Diagnostics questions
Is a code scan a full diagnosis?
No. A code records a detected condition. Further checks may be needed to determine why it happened.
Should I clear codes before coming in?
No. Clearing codes removes useful information and can reset emissions readiness monitors. Tell the team if codes were already cleared.
What helps with an intermittent problem?
Note when it happens, driving conditions, messages, and recent work. Do not use a phone to record symptoms while driving.
Can diagnostics guarantee a same-day repair?
No. Testing, parts, and scheduling depend on the findings. A diagnostic request is not a promised repair time.
