At Twisted Wrench Mobile Repair , we offer mobile computer diagnostic services for semi-trucks and heavy-duty vehicles in Junction City , OR , using dealer-grade tools to pinpoint issues fast and accurately—right at your location.

Vehicles are becoming more advanced day by day, and at their core is a complex network of sensors, control modules, and electronic systems. When something goes wrong under the hood, it’s not always visible. It makes computer diagnostics play a bigger role than ever before. At Twisted Wrench Mobile Repair , we provide on-site computer diagnostic services for semi-trucks, trailers, and diesel-powered vehicles throughout Junction City , OR , and surrounding areas.

Mobile Computer Diagnostics for Heavy-Duty Vehicles

ECMs (Engine Control Modules) and ECUs (Electronic Control Units) monitor nearly every aspect of your vehicle’s operation, from fuel delivery and emissions to brake performance and transmission behavior.

When one of these systems detects a fault, it logs a trouble code, which can trigger a warning light or cause performance issues. Computer diagnostics involves using unique scan tools to read these codes, interpret their meaning, and determine the best course of action.

Diagnostic work requires experience and insight, especially with the complexity of heavy-duty vehicles and diesel engines. That’s where Twisted Wrench Mobile Repair comes in. We bring dealership-grade equipment and certified expertise straight to your location, so you get fast answers and expert repairs.
