Our Check Engine Light Diagnostic Process
Our diagnostic process connects the warning light to what your vehicle is doing on the road, then gives you clear information before you decide on repairs.
- Describe The Concern: Tell us when the light appeared, whether it’s steady or flashing, and any changes in starting, idling, acceleration, or engine performance.
- Test The System: We review stored diagnostic information and inspect related systems to distinguish a trouble code from the condition that triggered it.
- Review The Findings: We explain the results and recommended next steps before work proceeds, so repairs begin only with your approval.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
Diagnostic testing pairs the dashboard warning light with manufacturer-quality diagnostic equipment and technician-led inspection.
A Code Readout Isn’t a Confirmed Diagnosis
Diagnostic trouble codes point to a system or condition that needs investigation. They don’t automatically identify the part that needs replacement. More than one issue can produce similar code information, which is why our technicians look beyond the readout before recommending a repair.
Clearing a warning light without addressing the condition that triggered it can allow the light to return. Full Service Diagnostic Testing provides the information you need to decide whether to authorize repairs.
A dashboard warning light, rough running, hard starting, or loss of power can all be reasons to request diagnostic testing.
When to Schedule Check Engine Light Service in Lafayette
Schedule diagnostic service when a check engine light stays on, flashes, or appears alongside a change in how your vehicle runs. The onboard diagnostic system can detect a monitored condition before it becomes obvious during everyday driving.
Common reasons to request testing include:
- A steady or flashing check engine light
- Rough idling, hesitation, or stalling
- Hard starting or reduced engine performance
- Unusual noises or odors, or changes in fuel economy
- Loss of power while driving

What a Check Engine Light Can Indicate
A check engine light can be related to emissions controls, ignition, fuel delivery, air intake, sensors, or another monitored vehicle system. The light itself doesn’t identify the exact repair, so generic code definitions shouldn’t be treated as a confirmed diagnosis for your vehicle.

FAQs
-
Q. "What is the difference between a steadily lit and a flashing check engine light?"A steadily lit light means that a sensor is sending a signal to your vehicle's computer that something is wrong or it could simply mean that the sensor is out. If your check engine light is flashing, however, that means there is a serious issue and you should stop driving immediately.
-
Q. "Why is my check engine light on but nothing seems to be wrong with my vehicle?"If nothing within your vehicle stands out, then it is possible that it is just a minor issue such as a loose gas cap or a bad O2 sensor. It is still recommended to see a mechanic if the light doesn't disappear to check for any larger issues.
-

Q. "What to do if your check engine light turns on?"We recommend heading to your local auto shop as soon as you are able. This is typically a sign that there is an abnormality within your engine.
-
Q. "Is it safe to drive your car when the check engine light is on?"It depends. If you are experiencing other noticeable issues with your vehicle, it may be best to pull over. Otherwise, it is typically okay to drive to your local auto shop. You will want to get this checked sooner rather than later to avoid being stranded with a broken-down car.
