Dongfeng GX ABS electronic control unit assembly 3631010-TS361

As the "brain" of the Dongfeng GX’s ABS, the 3631010-TS361 assembly delivers centralized, millisecond-level control to prevent wheel lock-up and maintain steering stability during braking. It collects real-time data from 4-6 wheel speed sensors (sampling rate up to 1kHz) to monitor wheel rotation status: when it detects an impending lock (e.g., a wheel decelerating too rapidly on slippery roads), the ECU immediately calculates the optimal brake pressure adjustment and sends electrical signals to the ABS solenoid valves. This triggers cyclic pressure modulation (build-hold-release) for each wheel, ensuring maximum braking force while keeping wheels rotating. Additionally, the ECU coordinates with the Dongfeng GX’s other safety systems: it sends brake status signals to the instrument cluster (activating the ABS indicator light) and integrates with the OBD system to log diagnostic trouble codes (DTCs) for sensor/valve faults—simplifying maintenance and ensuring continuous ABS functionality

The 3631010-TS361 ABS ECU features a automotive-grade rugged hardware design to withstand the harsh operating environment of the Dongfeng GX’s under-vehicle or engine bay locations. The outer housing is constructed from die-cast aluminum alloy (e.g., ADC12) with a powder-coated finish, providing excellent mechanical strength to resist impact from road debris and vibration (up to 20G peak acceleration, compliant with ISO 16750-3). The internal circuit board uses conformal coating (epoxy or acrylic) to protect components from moisture, dust, and chemical corrosion (e.g., road salt, brake fluid splashes). Critical hardware components—such as the high-performance MCU (e.g., NXP S32K1 or TI TMS570), power management ICs, and signal amplifiers—are rated for an operating temperature range of -40°C to 105°C, ensuring stable performance in extreme weather (freezing winters, hot summers). The ECU also has an IP6K7 waterproof rating, allowing it to withstand temporary immersion in water (e.g., deep puddles) without damage—essential for under-vehicle-mounted electronics

The 3631010-TS361 is engineered with Dongfeng GX-specific technical parameters to maximize ABS efficiency and reliability. Its processing capacity (up to 100 MIPS) enables fast data analysis and control signal output—critical for modulating brake pressure within 20ms of detecting wheel slip. The ECU supports a wide operating voltage range (9V-32V), compatible with the Dongfeng GX’s 12V (passenger variants) or 24V (commercial variants) on-board electrical system, and includes overvoltage/short-circuit protection to prevent damage from electrical surges. For communication, it uses a high-speed CAN bus (250 kbps/500 kbps, compliant with SAE J1939) to exchange data with solenoid valves and the vehicle’s main ECU, ensuring low-latency signal transmission. Additionally, the ECU has a low standby power consumption (≤3W) to avoid draining the battery when the vehicle is off, and its memory (both flash and RAM) is sized to store DTCs and ABS control parameters long-term

The 3631010-TS361 ABS ECU assembly meets strict global automotive safety and quality standards to ensure reliability in critical braking scenarios. It is manufactured in accordance with ISO/TS 16949 (automotive quality management system) and complies with ISO 26262 (functional safety standard for automotive electronics), achieving ASIL B compliance—mandatory for components controlling safety-related systems like ABS. It also adheres to ECE R10 (electromagnetic compatibility) to prevent interference with other on-board electronics (e.g., infotainment, navigation) and resist external EMI (e.g., mobile phone signals). Each unit undergoes 100% factory testing, including: electrical performance testing (signal accuracy, voltage stability), environmental testing (temperature cycling, vibration, humidity), and durability testing (simulating 10-year/200,000km lifespan). To support customers, the ECU comes with a 24-month/40,000km warranty (covering both hardware and software defects) and dedicated technical support—including DTC interpretation and software calibration guidance for repair facilities
