Heavy-Duty Truck Repairs

Truck Diagnostics & Electrical Repair in Augusta & Savannah, GA

A check-engine light is a symptom, not a diagnosis. We run dealer-level software for Cummins, Detroit, PACCAR, and CAT to find the actual fault — then fix that, instead of throwing parts at a code.

System Overview

Diagnostics & Electrical

Modern trucks are rolling networks: dozens of modules, hundreds of sensors, and miles of wiring exposed to heat, vibration, and salt. The difference between a shop that guesses and a shop that diagnoses is the software and the discipline to follow the data. We run OEM-level tools  the same platforms dealers use to read what the ECM actually sees, test components against spec, and trace circuits to the failure point.

Our electrical work covers the whole chassis: starting and charging systems, batteries and cables, lighting and harness repair, dash gauges and warning systems, and cab HVAC diagnostics. Intermittent faults  the ones that vanish at the shop door are a specialty; we’ve built our process around catching what other shops give back unfixed.

Don't Wait

Signs You Need This Repair

Catching it early keeps a small fix from becoming a major rebuild.

01

Warning Lights or Derates

Codes and power derates are the ECM handing you the answer if the shop has the software to read it properly.

02

Hard Starts or Dead Batteries

Repeated jump starts mean a charging system or parasitic draw problem that testing will pin down in one visit.

03

Ghosts in the System

Flickering gauges, random warning lights, lights that work sometimes classic harness or ground faults we trace to the connector.

Can’t any shop just read the code?

Reading a code is easy; knowing what it means is the job. A generic reader shows the fault family our dealer-level software shows live sensor data, test procedures, and wiring detail, which is the difference between fixing the cause and replacing parts on a hunch

Usually. We identify the trigger, make the repair or a compliant temporary resolution, and get the truck out of limp mode same day in many cases.

Yes they’re our favorite ugly jobs. We use live data logging and systematic circuit testing to catch faults that only show up on the road.
