Truck Repair Service
Truck Diagnostics
Computer diagnostics and fault tracing for heavy-duty trucks and trailers.
A fault code tells you which circuit or system reported a problem. It does not tell you which part failed. Truck diagnostics is the work in between: reading the codes, reading the live data, testing the circuit and confirming the failure before anyone spends money on a component.
LS Truck Repair performs computer diagnostics and hands-on troubleshooting on heavy-duty trucks and trailers — engine, transmission, ABS, body and chassis faults, intermittent electrical problems and warning lamps that will not clear.

- Engine and drivability diagnostics

Why diagnosis before parts
Replacing a sensor because its code appeared is one of the most common ways money is wasted on a commercial truck. Wiring damage, corrosion, poor grounds, chafed harnesses and connector issues routinely set codes that point at a perfectly good component. Testing first costs less than replacing twice.
