JPRO Version History — What Changed in 2025 v2 vs 2025 v1 vs 2024 v3?

JPRO Version History — Why the Version Number Matters

Noregon releases JPRO updates that expand vehicle coverage, improve protocols, and fix bugs. Running an outdated JPRO version on a current-model-year truck can result in incomplete ECU detection, missing fault code definitions, or failed bi-directional tests.

JPRO 2025 v2 — Current Version

Category What Changed
New Vehicle Coverage 2024–2025 Kenworth T680 (updated PACCAR electronics); 2025 Peterbilt 579 (PACCAR MX-13 Euro VI variant)
Engine Updates Expanded Detroit Diesel DD15 Gen 5 parameter coverage; Volvo D13TC (Turbo Compound) bi-directional support added
J1939 Network Monitor Improved node identification on networks with 12+ ECUs; faster polling on high-traffic backbones

Engine Updates Full 2023 Cummins ISB6.7 medium-duty coverage; Mack MP10 initial support

Should You Upgrade to JPRO 2025 v2?

If you regularly work on 2023–2025 model year trucks, yes — upgrade. JPRO 2024 v3 and earlier lack complete ECU maps for 2024 Kenworth and Peterbilt electronics, meaning some fault codes appear with generic descriptions or are not read at all. JPRO 2025 v2 also fixes critical bugs on Cascadia recall-related diagnostic sessions.
