Module, Electric Power Steering (EPSM): Description

This vehicle features an Electric Power Steering (EPS) system. The EPS module is located in a powerpack that contains the motor, module and worm drive on the steering gear assembly. Since the steering system is fully electric - rather than traditional hydraulic - all of the power assist is provided via an electric motor system. This improves fuel economy, since there is no parasitic loss from a power steering pump, and reduces steering system-generated noise, and allows optimal tuning of feedback to the driver.

NOTE:

All diagnostics must be done through the electric power steering module for the electric power steering system. Refer to DIAGNOSTIC CODE INDEX . There are no serviceable parts inside the steering rack, module or EPS motor. If any part is found to be defective or needs replacement, motor, and module are serviced as a assembly.

For the removal and installation of the EPS module, refer to GEAR, REMOVAL and GEAR, INSTALLATION .
