What to include
Provide the year, make, model, ECU part number if available, full diagnostic trouble codes, symptoms, previous repair attempts, and the reason for the DTC off request. Clear details help avoid quoting the wrong service.
DTC off service review
DTC off review for ECU diagnostic trouble code requests.
Submit the exact codes, vehicle details, and ECU information so the request can be reviewed before any final invoice.
Review before quote
DTC off requests are evaluated after intake details are confirmed. We do not quote the final work blindly because the ECU type, software, fault history, and customer goal all matter.
Vehicle diagnosis still matters
A DTC can return because of a real vehicle-side issue, wiring fault, sensor problem, or prior repair attempt. The more diagnostic history included, the better the service review can be.
All makes and models
DTC-related ECU service requests can be reviewed for domestic, European, Asian, diesel, gas, hybrid, and EV-related control modules.
How the mail-in service works
Start with the intake form and the $150 diagnostic checkout. After payment, pack the ECU with your confirmation details, ship it to the service address, and wait for inspection. Once the module is reviewed, the shop contacts you with the result, the recommended service path, the full invoice, and the return shipping step.
What helps us quote faster
Include the year, make, model, engine, ECU part number, symptoms, scan codes, previous repairs, and whether the module has been opened, wet, replaced, or programmed before. Clear details help the technician connect the bench test to the vehicle complaint and avoid delays.
