Fiat Grande Punto Steering Eps 199 No Vdc

The steering column with original code 55701321 è is a component of the electric power steering system installed on Fiat B-segment vehicles, particularly on the Fiat Grande Punto. This EPS (Electric Power Steering) module integrates the assistance electric motor, the electronic control unit, and the torque sensor into a single mechanical body, allowing for a fully electronic management of steering force. The component è designed for vehicles lacking VDC/ESP systemand represents a fundamental element for the safety and handling of the vehicle.

Technical specifications

The steering column 55701321 è consists of:

• Mechanical body with splined shaftconnected to the upper column and the steering box;
• Integrated electric motor at 12 Vcapable of delivering assistance torque proportional to the force applied to the steering wheel;
• Torque sensor (flat sensor) for detecting the direction and intensityà of movement;
• EPS electronic control unit integrated into the body, with connection to the vehicle's CAN-BUS network;
• Mechanical supports and fixings for mounting on the dashboard structure.

The system è self-adaptive, with variable assistance map based on the speedà of the vehicle and operating conditions. The average weight of the complete module is around 6–7 kg.

Functionalityà

The EPS module helps reduce the effort required for steering, maintaining precise and light handling at low speedsà and a moreù stable behavior at high speeds.àThe integrated control unit processes signals from the torque sensor, vehicle speedà and other electronic modules, activating the motor proportionally. The system also allows for the automatic return function of the steering wheel and the’assisted force intervention only when necessary, reducing electrical consumption.
