Frequently asked questions
Do I need to send the whole vehicle?
No. ECU Repair Doctor is a mail-in service: you remove the module, pack it securely and ship it to our Scarborough, Ontario bench. Only the module travels.
How long does a module repair take?
It depends on the fault. We diagnose the module first; repairs that need parts ordered typically take 2 weeks to 2 months, and we confirm the timeline with your quote. Module cloning, programming, key programming and airbag resets are usually done next day, and coding is by appointment.
Will the repaired module need programming?
In most cases no. We repair your original module, so it keeps its VIN and immobilizer data and goes back in plug-and-play. When a replacement unit is needed we clone your data onto it.
Is the repair warrantied?
Yes. Every repair is covered by a 30-day warranty after the repair.
How do I get a quote?

Don’t replace it — repair it.
Most failed modules can be repaired for a fraction of the dealer replacement price, and come back cloned to your vehicle so there’s no extra programming visit.
