Volvo trucks, including VNL, VHD, and VN series, are known for their tech-forward engines and safety features. That also means you need a scanner that can keep up — especially with newer GHG17 and GHG21 emissions systems.
Best Laptop Setup: A diagnostic laptop with TT and Universal Diag for quick access to both Volvo and Mack systems.
Features to look for:
-
DPF regen & SCR test capability
-
Live parameter monitoring
-
Full access to MID codes and VECU modules

Don’t rely on generic scan tools — true Volvo diagnostics require dealer-level software, and Tech Tool is the gold standard.
