The DTC Database
Built by Mechanics,
for Mechanics.

Stop losing unbillable hours chasing the wrong fix. Real repairs from working techs, ranked by frequency — with the misdiagnosis traps that send you down a rabbit hole you can't charge for.

Founding member pricing locked in at launch. No spam. Just updates.

01 — Verified Fixes

Real Fixes, Not Textbook Theory

Every entry is built from real shop repairs by working techs — what actually fixed it, what parts were used, and the wrong diagnostic paths that waste your time and money. No textbook theory. No guessing.

02 — Built For The Tech On The Lift.

Built For The Tech On The Lift.

Most likely fix is always first. Diagnostic steps run cheapest to most expensive. TSBs called out by bulletin number. Everything a working tech needs, in the order you actually use it.

03 — Misdiagnosis Alerts

Know What Not to Replace

Every entry documents the wrong diagnostic paths — the parts that get swapped first and don't fix it. One comeback, one wasted part, one unbillable hour is one too many. Techs who diagnose right the first time order one part, fix it once, and keep their bays moving. That's how you keep your job. That's how you get a raise.

04 — Verified Quality

Verified By Working Mechanics. Not Algorithms.

Every entry is reviewed by an active tech before it goes live. No forum guesses. No AI hallucinations dressed up as repair procedures. If it's in here, a mechanic put their name on it. That's also why we pay techs to submit fixes nobody has documented yet. → Learn more about the Bounty Program

THE BOUNTY PROGRAM

We Hunt What Nobody Has Documented.

Working tech? We're hunting the codes nobody talks about — the ones with no forum thread, no YouTube video, no answer anywhere. The ones that sent you down a two-hour rabbit hole with nothing to show for it. You found the fix. We want to pay you for it. Sign up and we'll send you the details.
