📋 PRODUCT OVERVIEW — DIESEL SPECIALIST
This ELM327 OBDII diagnostic scanner is specifically engineered for diesel vehicles. It supports both 12V and 24V diesel systems — from light-duty diesel pickups to heavy-duty trucks and commercial vehicles. Built with the industrial-grade PIC18F25K80 chipset and Bluetooth 5.1, it delivers professional-grade diagnostics for diesel engines.
✅ Diesel-optimized: Full support for SAE J1939 protocol (heavy truck standard) plus all CAN-based diesel OBD-II protocols.
✅ Wide voltage tolerance: 5V–30V DC — works flawlessly on 12V and 24V diesel electrical systems.
✅ Extreme durability: -40°C to +85°C operating temperature, ideal for harsh engine bay conditions.
✅ Bluetooth 5.1: 2× range, 70% lower power consumption than BT 4.0 — stable remote diagnostics.
✅ 3-color LED indicator: Red (power), Green/Yellow flashing (active communication).
