Diagnosis & Repair

Once we receive your module, our technicians perform a full diagnostic evaluation — visual inspection under magnification, bench testing of power supply rails, communication line verification, and component-level fault tracing. We will contact you with findings and confirm the repair scope before any work begins. Most repairs are completed within 24–72 hours.

4
Tested & Shipped Back

After repair, every module goes through a full functional test cycle on our bench rig — power-up, communication verification, output driver testing, and simulated load conditions. We ship your repaired module back via tracked courier. Total turnaround including shipping: typically 5–7 business days.

  • The only car service in Calgary that I trust. When you come with any problem, they quickly determine the cause and solve it. In my experience, other services simply suck money from the client, come, start guessing, change unnecessary parts, but Maxim's service is specific, real professionals work. I recommend!

  • Got quoted almost $5000 at Volvo for the work they did at Maxim garage for $500. Failed TCM. They even went to extra mile and popped a dent out of my car free of charge. I didn’t even ask them to do it. Car drives like a dream now, and without a ginormous dent. Maxim Garage is fast, efficient, and price friendly. I highly recommend these guys. Go see them!
