Check Engine Light Diagnostics in College Station

Don't Guess. Get the Truth.
A generic scan tool only tells you "what" happened. It doesn't tell you "why." We offer Two Levels of Service to help you make the right decision for your vehicle.

Option 1: Preliminary Scan

FREE

We Pull Your Codes

We plug in our scanner, tell you the error code (e.g., P0420), and give you a printout.

Option 2: Pinpoint Diagnostic

$75

Fee Waived with Repair

We perform lab-scope testing to find the exact failed part and guarantee the fix.

Our Professional Diagnostic Process

Step 1: Free Code Scan

We scan the car for free to get the starting point (the P-Code) and check for TSBs via Identifix®.

Step 2: Circuit Inspection

We visually inspect fuses and wiring harnesses for rodent damage or heat stress before testing complex parts.

Step 3: Pinpoint Testing

Using a multimeter, we test voltage, resistance, and ground at the component to confirm failure.

Step 4: Lab Scope Verify

For intermittent "ghost" issues, we use a Lab Scope to visualize the electrical signal in real-time.

Step 5: Repair & Re-Test

After the repair, we drive-cycle the vehicle to ensure all monitors pass and the light stays off.

Common Diagnostic Questions

Is the code scan really free?

Yes. We will pull your codes and give you a printout for $0. If you want us to perform manual testing to find the cause of the code, that is our Level 1 Diagnostic ($75).

Is the diagnostic fee waived if I fix the car?

Yes. If our Level 1 testing reveals a needed repair (e.g., an alternator or O2 sensor) and you approve the work today, we waive the $75 fee completely. You only pay for parts and labor.

Why is my Check Engine Light blinking?

Stop driving immediately. A blinking light indicates an active engine misfire dumping raw fuel into the exhaust. This can destroy your catalytic converter ($2,000+). Call us.

Can you test my battery and alternator?

Yes. We use Topdon specialized testers to analyze your entire starting and charging system , not just voltage. We find the "ghost" electrical issues.

Local Feedback on Diagnostics

"I had an electrical problem with my car that, unfortunately, didnt show up when they sere checking it. I think they spent 40 minutes trying but since it didnt do its weird thing they didnt charge me for their time... No pressure. Wow! Not afraid to go back."
