DESCRIPTION & OPERATION
Variable Effort Steering (VES) system may also be referred to as Magna Steer steering system. VES system varies the effort required to turn the steering wheel, providing a firmer steering (road) feel and improved directional stability at higher vehicle speeds.
Electronic Brake/Traction Control Module (EBTCM) receives battery voltage from a fuse in the instrument panel fuse block while ignition switch is in RUN position. See WIRING DIAGRAMS. EBTCM is located in left front corner of engine compartment, near lower radiator support. (Scheme 1) As vehicle speed increases, EBTCM increases the amount of current to the bi-directional magnetic rotary Magna Steer actuator, located in the steering gear assembly. This increases steering effort and improves steering feel.
VES system consists of an EBTCM, Magna Steer actuator, and Vehicle Speed Sensor (VSS). EBTCM receives input from VSS through the Powertrain Control Module (PCM). Based on VSS input, EBTCM varies current flow to the Magna Steer actuator.
