What to Expect When You Bring in Your Vehicle
Our process is straightforward, so you know where things stand.
Step 1: Diagnostic Scan & Inspection
Our technicians connect to your vehicle’s OBD-II diagnostic system and retrieve stored trouble codes. From there, they perform component and sensor testing to pinpoint the root cause rather than stopping at the code itself. The Digital Vehicle Inspection captures photo documentation of findings throughout.
Step 2: Review & Approval
We share the inspection results with you, explain findings in plain language, and outline your repair options. You decide what to approve. Nothing moves forward without your sign-off.
Step 3: Repair & Warranty Coverage
Once approved, repairs are completed using manufacturer-quality equipment. Qualifying work is covered by the Nice Difference Warranty: 3 years or 36,000 miles, whichever occurs last. You leave with a clear record of what was done and confidence that the repair is backed.
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.
Honest Service, Backed by On-Site Ownership
Owner Aaron Tharp operates on-site at our Garland location, which means there’s real accountability behind every service interaction. You’re not dealing with a distant corporate structure. You have a point of contact who answers for the work.
Our approach is guided by the principle “Love your neighbor as yourself.” That shapes how we communicate: technicians explain every finding in plain language with no jargon, so you understand the recommended repairs before you approve anything. Christian Brothers Automotive Garland is also Veteran Owned, and we take the values that come with that seriously.
Understanding Your Check Engine Light
The check engine light can be triggered by dozens of conditions. Common causes include a loose or faulty gas cap, a failing oxygen sensor, a misfiring cylinder, catalytic converter issues, or a problem with the mass airflow sensor. Each requires a different repair approach, which is why a diagnostic that goes beyond basic OBD scanner codes matters. Trouble codes stored in your vehicle’s computer identify the affected system, but finding the actual cause requires additional component and sensor testing beyond code reading alone.
We use manufacturer-quality diagnostic equipment throughout every inspection. Driving with the check engine light on for an extended period can compound the underlying problem, particularly when the emissions system or engine performance is involved. Bringing the vehicle in promptly is a straightforward way to help protect against that.
Garland and Sachse drivers can schedule a check engine light diagnostic at Christian Brothers Automotive Garland online or by calling (972) 810-7532. We can help you understand what’s going on and what it can take to address it.
After the Diagnosis: Repair Options & Warranty Coverage
Once the root cause is confirmed, our team presents findings and repair options before any work begins. You review the plan and approve what makes sense for your situation. If follow-up repairs are needed, our Garland shop can handle them in the same visit across a full range of related services, including engine, fuel system, exhaust, and sensor work.
Depending on what the diagnostic uncovers, repairs can range from a straightforward gas cap replacement to oxygen sensor replacement, ignition coil replacement, catalytic converter service, or more involved engine work. After repairs are complete, the technician can reset the check engine light and verify whether the issue appears to be resolved before returning the vehicle.
Qualifying repairs are covered by the Nice Difference Warranty: 3 years or 36,000 miles, whichever occurs last. The warranty is honored at all Christian Brothers Automotive locations nationwide, so you’re covered even when you’re traveling.

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. "Do you offer a warranty?"As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a3-year/36,000-mile warranty on all the work that we do.

Q. "Can you provide service under my extended warranty?"Yes. At Christian Brothers Automotive, we work with all major extended warranty providers to make needed repairs for our customers. If you have an extended warranty, you can discuss your carrier with our team when scheduling an appointment and confirm that the work will be covered.

-
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.
