BCU Control Unit WG9716582011 Sinotruk Sitrak

Product Introduction

This BCU (Body Control Unit) WG9716582011 is an OEM core electronic control module exclusively for Sinotruk heavy-duty trucks (SITRAK C7H/G7S, HOWO T7H/TX7 series). It features a rugged, sealed black metal-plastic composite housing, a high-integration circuit board, and OEM-standard multi-pin waterproof connectors. As the “brain” of the vehicle’s body electrical system, it operates on a 24V power supply and is pre-programmed with Sinotruk’s original control logic. Manufactured to strict quality standards, it ensures stable signal processing and system coordination under high-vibration, extreme temperature, and electromagnetic interference environments typical of heavy-duty transportation.

Core Functions

1. Centralized Body System Control: Serves as the master controller for all body electrical functions, including lighting (headlights, taillights, turn signals), wipers, door locks, power windows, instrument panel communication, and auxiliary power management.

2. CAN Bus Communication Hub: Establishes two-way data transmission with the engine ECU, instrument panel, and various sensors via the CAN bus, realizing centralized monitoring and coordinated operation of the entire vehicle’s electrical system.

3. Fault Diagnosis & Protection: Integrates self-diagnosis functionality to detect open circuits, short circuits, and component failures in the body electrical system; triggers protective measures (e.g., circuit power-off) and sends fault codes to the instrument panel for troubleshooting.

4. Sealed & Anti-Interference Design: The fully enclosed housing provides IP67-level dustproof and waterproof performance; the internal circuit adopts electromagnetic shielding technology to resist interference from the vehicle’s engine and high-voltage systems, ensuring no misoperation.
