A code indicates the circuit or sensor reporting an anomaly, not the part to be replaced. We read live data, test the circuit, and confirm the issue before proposing a repair.


Intermittent warning lights, cold-start misfires, rising fuel consumption, or a fan that won't stop running: in these situations, replacing parts at random costs more than an hour of diagnostics.
FREQUENTLY ASKED QUESTIONS

Yes, if possible. The module keeps the code and the conditions that triggered it in memory, even after the light goes out. This data disappears after a certain number of drive cycles.
It provides the generic engine code. It generally does not access transmission, braking, or convenience modules, nor does it provide the live data needed to distinguish a faulty sensor from a real mechanical defect.
The evaluation is usually free. A garage may charge a fee, but only if they inform you of the exact amount before performing it, and that amount must include reassembling the vehicle.
Yes. A mechanic must provide a written estimate for any repair over $100, and the amount cannot be exceeded without your authorization.
It depends on the code. A flashing light, overheating, or loss of power requires you to stop. We will clearly tell you in writing what can be postponed and what cannot.
