Dongfeng KL Central control unit assembly - including software and hardware 3600030-C3300

Engineered to match the Dongfeng KL’s original electrical architecture, this CCU assembly seamlessly integrates with the vehicle’s dual CAN bus system (CAN 2.0B protocol, baud rate 500kbps for powertrain, 250kbps for body control) and LIN bus (for low-speed peripherals like door locks). It features 16 CAN/LIN communication ports with gold-plated pins—ensuring stable signal transmission even in high-vibration environments (up to 2000Hz vibration resistance). The unit’s pinout configuration is identical to the OEM CCU, with color-coded wiring harnesses (e.g., yellow for CAN_H, green for CAN_L) that plug directly into the Dongfeng KL’s existing connector, eliminating the need for rewiring or adapter modules. This compatibility guarantees no communication conflicts with the truck’s original ECMs, such as the engine control unit or anti-lock braking system

Beyond basic vehicle control, the CCU assembly offers comprehensive functional support for Dongfeng KL’s operation needs. It includes 8 analog input channels (for monitoring oil pressure, coolant temperature, and battery voltage) and 12 digital input/output channels (for controlling relays, LEDs, and solenoids). The built-in diagnostic system complies with ISO 15031-6 standards, capable of detecting faults in connected modules (e.g., sensor malfunctions, short circuits) and storing DTCs (Diagnostic Trouble Codes) in non-volatile memory. Drivers or technicians can retrieve DTCs via the truck’s instrument panel or a diagnostic scanner (e.g., Dongfeng DTS software), with detailed fault descriptions (e.g., “P0121: Throttle Position Sensor Circuit Range/Performance Problem”) to accelerate maintenance

Constructed to withstand the harsh operating conditions of heavy-duty trucks, the CCU assembly features a die-cast aluminum housing with an anodized surface treatment—providing excellent heat dissipation (thermal resistance: 0.8℃/W) and impact resistance (able to withstand 500N static pressure). The internal circuit board uses automotive-grade components (e.g., Texas Instruments voltage regulators, TE Connectivity capacitors) with a wide operating temperature range of -40℃ to +85℃, ensuring stable performance in extreme cold (e.g., northern China winters) or high-temperature (e.g., southern China summers) environments. The unit also achieves an IP6K9K protection rating, with a rubber gasket-sealed connector and waterproof potting compound (epoxy resin) on the circuit board—preventing damage from water, dust, or high-pressure washing (common in truck maintenance)

This CCU assembly meets strict automotive safety and quality standards, including ISO 26262 ASIL-B (functional safety for road vehicles) and IATF 16949 (quality management for automotive components). It undergoes 100% factory testing—including 1000-hour high-temperature aging tests, 500-hour vibration tests, and 100-cycle thermal shock tests—to ensure reliability. Installation is user-friendly: the unit weighs only 1.2kg and mounts to the Dongfeng KL’s dashboard bracket via 4 M6 stainless steel bolts (included in the package). The pre-integrated software requires no additional calibration after installation—once powered on, it automatically synchronizes with the truck’s ECMs within 30 seconds, minimizing downtime for maintenance or replacement. Additionally, the assembly comes with a 24-month warranty, covering defects in materials or workmanship
