What Does a Full Diagnostic Do?

A full diagnostic on a semi-truck involves using a heavy-duty truck scanner tool to check the vehicle's systems and components for any issues or malfunctions. This diagnostic tool can read and interpret data from the truck's onboard computer, including engine codes, transmission codes, and ABS codes. The diagnostic tool can also perform a full-system diagnosis, which checks all of the truck's systems and components, including the engine, transmission, brakes, and more. 

A full diagnostic is an essential part of regular maintenance for semi-trucks, as it can help prevent breakdowns and costly repairs down the line.

What Are the 3 Most Common Causes of Electrical Problems?

The three most common causes of electrical problems on semi-trucks are:

  1. Problems with the ECU: The ECU (Engine Control Unit) is responsible for controlling the engine's performance and efficiency. Loose or broken wires can cause short circuits and fires, and unsecured cables can produce electrical "noise" that interferes with the truck's onboard computer systems. This can lead to engine, transmission, and other system issues.
  2. Battery Issues: Dead batteries, poor battery life, and malfunctioning glow plugs are common electrical problems in semi-trucks. These issues can cause difficulty starting the engine and other performance problems.
  3. Wiring Issues: Wiring problems, such as blown fuses, weak connections, and damaged cables, can cause electrical problems in semi-trucks. These issues can lead to dimming or flickering lights, faulty starters, and other performance issues.
