Car & Truck Diagnostics in Markham
Diagnosis is where good repairs start. We specialize in finding the real cause of warning lights and hard-to-find problems on gasoline and diesel vehicles, so the right repair happens the first time.
What it is
Modern vehicles are run by computers that monitor the engine, transmission, brakes and electrical systems. A scan tool reads the fault codes they store, and an experienced technician uses that data with hands-on testing to pinpoint the actual problem instead of guessing.
Signs you should book a visit
- Check engine or other warning light on
- Stalling, hesitation or rough running
- Starting or no-start problems
- Electrical faults, lighting or battery drain
- Poor fuel economy
