PRODUCT DESCRIPTION
Vehicle Compatibility & OE Standards
Exclusively developed as an Original Equipment (OE) replacement part for Dongfeng VR series commercial vehicles, this upper control unit assembly (7916010-C5100) adheres to strict Dongfeng engineering specifications and quality standards. It is fully compatible with Dongfeng VR models equipped with Euro VI emission-compliant engines and automated manual transmissions (AMTs), ensuring perfect fitment without the need for modification to the vehicle’s existing wiring harness or mounting brackets. Each unit undergoes factory pre-calibration to match the specific vehicle VIN (Vehicle Identification Number) parameters, guaranteeing immediate functionality and consistent performance upon installation
Durability & Environmental Resilience
Constructed with high-grade industrial materials, the Dongfeng VR Upper Control Unit Assembly (7916010-C5100) is built to withstand harsh operating environments common in commercial vehicle use. The outer housing features a IP6K9K-rated protective enclosure (dust-tight and resistant to high-pressure, high-temperature water jets), preventing damage from moisture, dust, and road debris. Internal components are coated with anti-corrosion materials, and the unit is tested to endure extreme temperature fluctuations (-40°C to +85°C) and vibration levels (up to 20G acceleration), ensuring reliable operation over a service life of 500,000+ kilometers under typical heavy-duty driving conditions
Performance Optimization & Safety Features
This upper control unit assembly is programmed to enhance both vehicle efficiency and safety. It dynamically adjusts fuel injection timing and engine torque output based on load conditions, reducing fuel consumption by up to 5% compared to older control unit models while maintaining maximum power delivery. Additionally, it integrates advanced safety protocols, including over-speed protection, engine overheat shutdown, and fault diagnosis for critical systems (e.g., brake hydraulics, ABS). The unit stores real-time diagnostic trouble codes (DTCs) and transmits data via CAN bus to the vehicle’s instrument cluster, enabling drivers and technicians to quickly identify and resolve issues, minimizing downtime and improving overall operational safety
Technical Specifications & Installation Convenience
The Dongfeng VR Upper Control Unit Assembly (7916010-C5100) features a compact design with dimensions of 185mm (L) × 120mm (W) × 85mm (H) and a weight of 1.2kg, allowing for easy installation in the vehicle’s dedicated electronic control compartment. It operates on a 24V DC power supply (compatible with Dongfeng VR’s standard electrical system) and has a maximum operating current of 15A. The unit is equipped with a 32-pin waterproof connector that uses gold-plated terminals to ensure low electrical resistance and stable signal transmission. For maintenance, it supports firmware updates via a standard OBD-II port, enabling technicians to install software upgrades without disassembling the unit, further reducing service time and costs
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
