Modern trucks use digital dashboards, ECUs, and diagnostic ports (OBD-II) to monitor performance. Drivers must understand basic warning lights and battery care.
Battery terminals must be clean and secure—especially in cold climates.
Warning lights (ABS, engine, brake) must be reported immediately.
GPS, tachograph, and telematics systems rely on stable electrical supply.
Hungary and Germany require functioning lights and reflectors for night driving.
Purpose for Training: To train drivers in recognizing electrical issues, interpreting dashboard alerts, and maintaining digital systems for compliance and safety.
