Your dash just lit up — now what? This 5-page guide covers the most common fault codes across Cummins, Detroit, International, Volvo, Mack, and PACCAR (plus Hino and Isuzu), and gives you a simple 5-step plan to decide: keep driving, head to a shop, or stop right now. Built by a 6-year diesel mechanic — not repair instructions, just the fastest way to know if you’re in real trouble or fine to keep rolling.
