A post-repair diagnostic scan checks that a completed auto collision repair introduced no new fault codes and that every electrical and safety system reports normal function. At Redeemed Auto Body, we run it after the physical repair is complete, so you drive away knowing every system works as it should.
Key Takeaways:
- What it confirms: Automakers, including Ford, publish position statements confirming that a post-repair scan must show no new diagnostic trouble codes (DTCs) and full system restoration. We follow the applicable OEM’s standard on every job, regardless of make.
- When it happens: We run the scan after every physical repair step is complete, right before final quality control and delivery.
- Why clearing a code isn’t enough: We never erase a DTC without diagnosing its cause, since that can leave damaged wiring or a faulty sensor unresolved, per I-CAR’s collision repair guidance.
What Does a Post-Repair Scan Actually Check?
We read every computer module on the vehicle, not only the ones tied to the visible repair, to confirm the collision and the repair process left no new fault codes behind.
We also check that safety systems, including airbags, stability control, and driver-assist sensors, report normal status.
Why Clearing a Code Isn’t the Same as Fixing It
A diagnostic trouble code can be erased with a few clicks, but that doesn’t fix whatever triggered it. Wiring can be pinched or chafed during a collision in ways that never show up on a visual inspection, and a cleared code with no diagnosis just hides the problem until it resurfaces.
At Redeemed Auto Body, we trace each code back to its source using our OEM repair information before we close it out, using our AirPro and Opus scanning tools to read and interpret the data. That’s different from a shop that treats the post-repair scan as a formality to clear before handing back the keys.
Pre-Repair Scan vs. Post-Repair Scan
| Detail | Pre-Repair Scan | Post-Repair Scan |
| Timing | Before repairs begin | After repairs are complete |
| Purpose | Finds hidden damage to build the repair plan | Confirms no new faults and full system restoration |
| Result | Informs what parts and procedures are needed | Clears the vehicle for delivery |
What Happens If a Post-Repair Scan Finds a New Fault Code?
- Trace the code to its source. We use our OEM repair information and diagnostic data to find the actual cause behind the code, beyond its generic definition.
- Repair the cause, not the symptom. We fix the damaged wire, connector, or module instead of clearing the code and moving on.
- Re-scan to confirm. We run the scan again to verify the code doesn’t return.
- Document the findings. Every result goes in the repair file we keep for you, alongside the rest of your job’s documentation.
That level of follow-through is part of what separates real collision repair services from a shop that only scans because an estimated line item requires it, and it’s how we run every job at Redeemed Auto Body. If you’re comparing collision centers for a repair involving airbags, sensors, or safety modules, ask what happens when their scan finds something. Here is what our customer Cheryllynn L. said in a Google review: “They are exceptional !!! I checked their reviews, and I must say they were everything I read. They kept me updated and did a fantastic job repairing all my damages, plus informed me of damages I may not have known about. 10/10 I would recommend them to everyone.”
Frequently Asked Questions
Does a post-repair scan add time to my repair?
A little, but we built it into the repair plan from the start. A clean scan takes minutes; a scan that turns up a fault code we need to trace can add more, depending on what it finds.
Is a post-repair scan the same as ADAS calibration?
No. The scan reads fault codes and confirms systems are communicating correctly. ADAS (Advanced Driver Assistance Systems) calibration is a separate step that aims cameras and sensors to exact factory specifications, and we sublet that work to the dealership.
Will I get documentation of my vehicle’s scan results?
Yes. We keep a Google Drive folder for every repair with your documents, so you can see exactly what was checked.
