Nissan Electro Hydraulic Steering

Nissan’s steering system is susceptible to driver-error. Here’s what to look for in these systems.

Nissan’s electro-hydraulic power steering system provides the same feel of a conventional hydraulic power steering system while improving fuel economy by using an electric motor to power the pump. The system is comprised of the electro-hydraulic pump assembly, control module and steering gear.

The power steering module is on top of the pump, and the motor controls the speed of the power steering pump according to vehicle speed and steering angle. By changing the pump speed, the module controls the steering assist force. The control module is connected to the hi-speed CAN bus that ties the engine control module (ECM) and ABS module. The ABS module provides vehicle speed and steering angle, and torque data to the power steering system. The connection to the ECM allows the alternator to provide enough power when the pump is running.
