Steering assistance
Supplier:KOYO.
The steering assistance is rpovided by the assistance motor
(12),
controlled by the ECU.
Power delivered to the assistance motor
(12)depends on:
Speed of the vehicle.
Torque applied on the steering wheel.Only one ECU version, whatever the enginetype.
The electric power steering ECU is linked to the following connectors:
(6)Assistance motor supply.
(13)Electric power steering ECU supply.
(14)Control signals.
After changing the electric power steering ECU, it is necessary to
perform a configuration.
