Full Electrical Diagnostics
Our technicians use OEM-grade scanners and oscilloscopes to trace even the most elusive electrical faults. We start with a battery and alternator health check, then map voltage drops across every critical circuit. CAN-bus data is analysed in real time, allowing us to pinpoint shorts, opens, and sensor failures without guess-work. Detailed reports translate codes into plain language, so you know exactly what needs attention. Repairs are completed with weather-sealed connectors and heat-shrink for long-term reliability. Final tests ensure all warning lights stay off and systems communicate flawlessly.
OEM-Grade Scanners
Reads every ECU, ABS, and body module without guess-work.
Real-Time Data Logging
Captures live voltage and waveform values while the truck runs.
Actionable Reports
Clear pass / fail status with step-by-step fix recommendations.
Pinpoint Electrical Issues Before They Become Breakdowns
Modern heavy-duty trucks rely on dozens of sensors, controllers, and miles of wiring. A single loose ground can sideline a load and cost hours of downtime. Our Full Electrical Diagnostics program uses dealer-level tools and oscilloscope analysis to find shorts, opens, and intermittent faults fast—so you can schedule repairs, not emergency tows.
