NBCU WG9716583001 Sinotruk Sitrak

Product Introduction

This NBCU (New Body Control Unit) WG9716583001 is a high-end OEM electronic control module co-produced by Sinotruk and Continental Automotive (Jinan) for premium heavy-duty truck models (SITRAK C9H, G7H, HOWO TH7). It upgrades the traditional BCU with higher integration, faster CAN bus communication speed, and expanded functional coverage. The unit features a reinforced sealed black plastic housing, color-coded OEM waterproof connectors (blue, beige, green), and a pre-calibrated high-performance circuit board. Optimized for 24V heavy-duty truck electrical systems, it delivers ultra-stable performance against electromagnetic interference, extreme temperatures (-40℃ to 85℃), and long-term chassis vibration.

Core Functions

1. Next-Gen Body Electrical Hub: Integrates control of advanced body systems including intelligent lighting (auto headlight, adaptive DRL), keyless entry/start, climate control, electronic parking brake, and multi-media interface—surpassing the functional scope of standard BCUs.

2. High-Speed CAN FD Communication: Adopts CAN FD protocol for ultra-fast data transmission with the engine ECU, instrument cluster, ADAS system, and sensors, ensuring real-time synchronization of intelligent vehicle functions.

3. Comprehensive Diagnostic & OTA Support: Built-in full-system self-diagnosis (covering 1000+ fault codes) and supports Sinotruk’s official OTA (Over-the-Air) programming, enabling remote firmware updates and parameter calibration without disassembly.

4. Enhanced Safety & Protection: Features over-voltage/under-voltage protection, reverse polarity protection, and short-circuit auto-shutdown. The IP67 sealed structure and electromagnetic shielding design prevent water, dust, and interference from affecting internal circuits.
