Component-Level Repair, Not Just a Reset

ECU Repair Doctor was built around one idea: most “dead” modules aren’t actually dead. We open them up, diagnose the real fault, and repair it at the component level — the same units dealers write off as full replacements.

// How It Works

Our Simple Mail-In Repair Process

1. Contact Us
Tell us your module’s fault symptoms and any diagnostic trouble codes (DTCs) so we know what we’re dealing with.
2. Ship It In
Pack your module securely and mail it to 76 Sherry Road, Unit H, Scarborough, Ontario.
3. Repaired & Returned
We bench-test and repair at the component level, then ship your module back tested, working, and warrantied.

Why shops and drivers send us their modules

ECU Repair Doctor is a Canadian electronic module repair specialist based at 76 Sherry Road, Unit H, Scarborough, Ontario. We work for drivers, independent repair shops, locksmiths and fleets.

Repair beats replacement

A new module from the dealer is expensive and still has to be programmed to your car. Most failures are a handful of burnt or cracked components, which we replace at the component level so your original module goes back in.
