Description - ELECTRIC STEERING - Fiat GRANDE PUNTO 1.3 Multijet

The EPS (Electrical Hydraulic Power Steering) is a power assisted steering device designed to reduce the effort required for steering the vehicle by using the torque from an electric motor.An electronic control unit manages and controls the system: processing the input information and using the internal operating logic, the control unit determines the direction of rotation and the supply current for the electric motor producing the desired servo-assistance effect.A CITY button on the control unit in the centre of the facia can be used to alter the power-assistance level of the electric steering device.An electric power steering failure warning light is present on the instrument panel. CITY function activation is indicated by a warning light on the control panel.For more details.The control unit power supply lines are protected by a special maxifuse located on the battery; the ignition-operated supply is protected by a specific fuse in the Body Computer.

Operational description - ELECTRIC STEERING - Fiat GRANDE PUNTO 1.3 Multijet

The electrohydraulic power assisted steering control unit M86 controls and regulates the electrically operated steering system.The direct power supply for the control unit arrives from the battery via the line protected by maxifuse F6 of the maxifuse case on battery B99 at pin A of connector A of M86. Pin B of connector A of M86 is earthed.The ignition-operated power supply arrives via a line protected by fuse F21 of Body Computer M1 at pin 1 of connector B of M86.Body Computer M1 - connector G - is supplied directly from the battery from a line protected by maxifuse F2 of engine compartment control unit B1. It is ignition-operated (INT) at pin 32 of connector D. Pin 10 of connector H of M1 supplies a reference earth to the Body Computer.Control unit M86 is connected via the CAN - pin 7 and 8 of connector B - to the other nodes and in particular Body Computer M1 and instrument panel E50, to which it sends signals for the electric power steering warning light and the CITY function activation signal.The CITY function selection button (less effort to turn the steering wheel) is located in the control unit in the centre of the facia H90: the activation earth signal is received from Computer M1, pin 49 of connector D while the CITY function activation signal is sent to pin 28 of the same connector.
