Our technicians use OEM-level diagnostic scanners and software to provide dealer-quality diagnostics at competitive prices. We diagnose all truck systems accurately the first time.
Complete scan of all vehicle modules to identify stored and pending fault codes. We interpret codes in context to determine the root cause.
Real-time monitoring of engine parameters, sensor readings, and system performance to identify issues that may not trigger fault codes.
Comprehensive emissions diagnostics including DPF, SCR/DEF, EGR, and NOx systems. Ensure compliance with Ontario regulations.
Testing of charging systems, starter circuits, battery health, and CAN bus communication to identify electrical faults quickly.
Specialized scanning of transmission control modules, shift solenoids, speed sensors, and fluid pressure to diagnose shifting issues.
Power output analysis, fuel efficiency testing, and system benchmarking to identify performance degradation before it becomes costly.
At Fair Price Truck Repair Center, accurate diagnostics are the foundation of every successful repair. Our no-guesswork approach means you only pay for repairs you actually need.
Serving Etobicoke, Toronto, Mississauga, Oakville, Brampton, and the entire GTA.
When you bring your truck to Fair Price Truck Repair Center for diagnostics, the process begins with a thorough initial consultation. Our technicians will discuss the symptoms you have noticed, review any warning lights on the dashboard, and ask about recent maintenance or repairs. This conversation helps us narrow down potential causes before we connect any equipment, saving time and ensuring we focus on the right systems from the start.
Next, we connect your truck to OEM-level diagnostic scanners specific to your vehicle's manufacturer. For Volvo trucks, we use Volvo VOCOM to access every module in the vehicle. Cummins-powered trucks are scanned with Cummins INSITE, which provides deep engine and aftertreatment data. Detroit Diesel engines are diagnosed using Detroit Diesel Diagnostic Link (DDDL), the factory tool that reads proprietary fault codes and parameters. We also carry diagnostic software for Freightliner, Kenworth, Peterbilt, International, and Mack, so no matter what you drive, we have the right tool for an accurate diagnosis.
Once the scanner is connected, our technicians perform a full fault code scan across all vehicle modules, including the engine control module, transmission control module, ABS, instrument cluster, and aftertreatment system. We go beyond simply reading codes. Live data streams are reviewed in real time to identify sensor values that are out of range, intermittent faults that may not trigger a stored code, and performance trends that indicate developing problems. Freeze frame data is analyzed to understand the exact conditions under which a fault occurred.
After the diagnostic session is complete, we compile a written report that clearly explains every fault found, what it means in plain language, and our recommended repair path. The report includes prioritized repair recommendations so you can address critical safety and drivability issues first, along with transparent cost estimates for each repair. There are no surprises and no pressure. You decide which repairs to authorize, and we proceed only with your approval.
Costs vary based on complexity. We offer competitive rates — call (647) 706-9257 for current pricing.
It indicates your truck's computer has detected an issue ranging from a minor sensor problem to a serious engine or emissions fault. Professional scanning is required to read the specific codes.
A standard scan takes 30-60 minutes. Complex issues may take 1-3 hours. We provide time estimates after the initial scan.
Yes, we use data logging, freeze frame data, and live monitoring to track down issues that don't appear consistently.
Yes — DPF checks, SCR/DEF analysis, EGR valve testing, and NOx sensor verification for Ontario emissions compliance.
Don't ignore warning lights. Our fast, accurate diagnostics identify the problem so you can get back on the road.
