When it comes to running heavy-duty vehicles, reliability isn’t a luxury — it’s a necessity. Trucks are the lifeblood of logistics, transport, and construction industries, often working around the clock under immense pressure. At Kearney Group Diagnostics (KGD), we know how costly downtime can be. That’s why our Truck Diagnostic Services are designed to keep your fleet running smoothly, efficiently, and safely — mile after mile.
What Is Truck Diagnostics?
Truck diagnostics involve using advanced diagnostic tools to connect directly to your vehicle’s Electronic Control Units (ECUs). These systems constantly monitor the performance of vital components such as the engine, gearbox, exhaust, and braking systems.
Our diagnostic technology allows us to read and interpret fault codes, giving us deep insights into what’s happening inside your truck’s complex systems. From there, we can identify issues before they lead to mechanical failures — saving you time, money, and costly breakdowns.
Why Truck Diagnostics Are Essential
Trucks are built to endure, but their sheer workload takes its toll. Long hauls, heavy loads, and constant use all contribute to wear and tear. Preventive diagnostics are your best defence against unexpected breakdowns.
Here’s why regular diagnostics are vital for your trucks:
- 💰 Reduce Maintenance Costs – Early detection prevents minor issues from turning into expensive repairs.
- 🕒 Minimise Downtime – Keep your trucks on the road, not in the workshop.
- ⚙️ Optimise Performance – Ensure your vehicle operates efficiently, maximising power and fuel economy.
- 🌍 Stay Emission Compliant – Detect and fix DPF or SCR (AdBlue) faults before they affect emissions compliance.
- 🛡️ Enhance Safety – Identify brake, suspension, and electrical faults that could compromise driver safety.
A single unplanned breakdown can cost hundreds — if not thousands — in lost deliveries and recovery fees. Routine truck diagnostics are an investment that keeps your business moving without interruptions.
What We Check During a Truck Diagnostic
At Kearney Group Diagnostics, we perform a thorough examination using industry-leading diagnostic tools compatible with major truck manufacturers. Our checks cover:
- Engine and transmission management
- ABS, traction control, and stability systems
- Exhaust and emission systems (including DPF and AdBlue)
- Fuel injectors and turbo systems
- Electrical wiring and ECU communication
- Braking, air suspension, and steering sensors
Once your diagnostic check is complete, we’ll provide a comprehensive digital or printed report, detailing all fault codes, their meanings, and recommended actions. Transparency is key — we’ll explain everything clearly and honestly so you can make informed decisions.
