A breakdown can involve several connected systems. We combine scan information, electrical measurements and mechanical inspection to understand what has failed and what can be repaired safely at the truck. A fault code helps guide testing; it does not, by itself, prove which part needs replacing.
No-start & charging faults
Battery, starter, alternator and charging-system testing, including power supply, isolation, voltage drop and earth connections. We can investigate accessible wiring, lighting, sensor and control-circuit faults where the site and repair scope allow.
Warning lights & lost power
Derating, poor performance, hard starting and smoke can involve fuel delivery, air intake, sensors, wiring or mechanical condition. Live data, operating symptoms and physical checks help establish the next step before major parts are recommended.
Overheating & coolant leaks
Cooling-system pressure testing and checks for coolant loss, hose faults, fan operation and other overheating causes. Suitable hose, belt, clamp and accessible leak repairs may be completed on site when conditions and parts allow.
Brake & air-system concerns
Assessment of accessible brake, air-loss and pneumatic faults, with attention to the truck’s operating condition. Work requiring safe lifting, wheel-end access or more extensive dismantling can be directed into the workshop.
Truck-to-trailer faults
Lighting, plugs, wiring, power supply and air connections can affect the whole combination. We assess suitable trailer electrical, pneumatic and mechanical concerns, including accessible running gear, rather than looking at each unit in isolation.
Practical on-site repairs
The mobile workshop carries tools and diagnostic equipment for suitable mechanical and electrical work. Scope depends on access, safety, the fault and available parts. Larger failures receive repair planning and transport recommendations where needed.
