A Warning Light Is Information — Not the Complete Answer.

Today's trucks rely on electronic modules, sensors, wiring networks, and computerized control systems.

When a warning indicator appears, retrieving a fault code may only be the beginning of the diagnostic process.

Our approach is to use diagnostic information together with physical inspection and testing to narrow down the source of the problem.

Diagnostic work may involve:

  • Engine Controls
  • Transmission Controls
  • ABS Systems
  • Electrical Systems
  • Sensors & Wiring
  • Aftertreatment Systems
  • DPF / DEF / SCR Systems
  • Performance Concerns

Accurate troubleshooting can help avoid unnecessary parts replacement and repeated visits for the same concern.
