The EBS3.1 Electronic Control Unit is the brain of the braking system, featuring a 250kb memory capacity and advanced processing power. It manages all EBS functions including anti‑lock braking, traction control, and electronic stability control, delivering precise modulation of brake pressure to each wheel for optimal stopping performance.
The ASR/ESC Off Switch allows the driver to temporarily disable the Anti‑Slip Regulation and Electronic Stability Control functions when required, such as when driving on loose surfaces or deep snow. The switch is ergonomically placed on the dashboard and provides clear visual feedback when activated.
The C7H Steering Angle Sensor is a precision device mounted on the steering column that continuously measures the steering wheel position and rate of rotation. This data is sent to the EBS3.1 ECU to determine the driver’s intended direction, enabling the ESC system to apply selective braking to maintain vehicle stability during evasive maneuvers.
The Cross Recessed Pan Head Screw is used to secure the steering angle sensor and other components within the EBS Electronic Control System. Its cross recess design allows for easy installation and removal with a standard screwdriver, ensuring a reliable and vibration‑resistant fastening.
The Plain Washer is used under the screw heads to distribute clamping pressure and protect the mounting surfaces from damage. It provides a smooth bearing surface and helps maintain consistent torque during assembly.
The Spring Washer is a split‑ring lock washer that provides tension to prevent the screws from loosening under vibration. It is essential for maintaining the integrity of the EBS Electronic Control System’s mounting in the high‑vibration environment of a heavy truck.
Our EBS Electronic Control System is manufactured to Sinotruk’s original specifications, ensuring seamless integration with the C7H’s existing braking and electrical architecture. The EBS3.1 ECU, steering angle sensor, and ASR/ESC switch are all calibrated to work together perfectly.
The EBS3.1 system provides comprehensive safety functions including ABS, ASR, ESC, and hill‑hold assist. The steering angle sensor enables precise stability control, significantly reducing the risk of rollover and loss of control in emergency situations.
We supply all necessary mounting hardware – cross recessed pan head screws, plain washers, and spring washers – to securely install the steering angle sensor and other components. No additional parts are needed, simplifying the replacement process.
All components are built to withstand the demanding conditions of heavy truck operation, including extreme temperatures, vibration, and moisture. The EBS3.1 ECU is fully sealed and tested to ensure long‑term reliability.
The EBS Electronic Control System is a comprehensive safety solution that integrates the EBS3.1 ECU, steering angle sensor, and driver controls into a unified electronic braking architecture. It replaces outdated pneumatic systems with intelligent, electronically controlled braking for faster response and better modulation.
The EBS3.1 ECU is the heart of the system, featuring a 32‑bit processor with 250kb of flash memory for storing vehicle‑specific parameters. It communicates with the steering angle sensor, wheel speed sensors, and brake actuators over the CAN bus to provide precise braking force distribution.
The C7H Steering Angle Sensor is a non‑contact hall‑effect sensor that delivers accurate steering angle data with a resolution of 0.1°. This high precision enables the ESC system to detect understeer or oversteer conditions and apply corrective braking within milliseconds.
The ASR/ESC Off Switch provides the driver with the flexibility to temporarily disable traction and stability controls when operating on surfaces where wheel spin is necessary, such as mud or deep gravel. The switch is spring‑loaded to prevent accidental activation and includes an LED indicator.
Installation of the steering angle sensor requires careful alignment with the steering column’s center position. The included cross recessed screws and washers ensure a secure and vibration‑proof mounting, essential for accurate sensor readings.
The EBS Electronic Control System is fully compatible with the C7H’s existing diagnostics, allowing fault codes to be read and cleared using standard OBD‑II or J1939 diagnostic tools. This simplifies troubleshooting and reduces workshop downtime.
We recommend replacing the steering angle sensor and ECU together when upgrading an older braking system, as this ensures optimal compatibility and calibration. Our kit provides all components needed for a complete upgrade.
The EBS3.1 ECU supports advanced functions such as brake blending, where the retarder and service brakes are coordinated to provide smooth deceleration with minimal wear. This feature extends brake life and reduces operating costs.
Regular inspection of the steering angle sensor and its wiring is recommended to ensure accurate data transmission. Signs of wear include intermittent ESC warnings or erratic steering feel. Replacing the sensor with our genuine part restores full performance.
For fleet operators, maintaining a consistent EBS Electronic Control System across all vehicles simplifies training and diagnostic procedures. Using genuine components ensures that all trucks perform identically under braking.
The EBS3.1 ECU is pre‑programmed with the C7H’s specific axle weights, tire sizes, and brake configurations, eliminating the need for complex calibration after installation. This plug‑and‑play design saves time and ensures correct operation.
The ASR/ESC Off Switch is designed to be mounted in the standard dashboard switch panel, with a connector that matches the C7H’s interior wiring harness. It includes a blue LED that illuminates when the functions are deactivated.
