SOURCE: eps light is on and steering is stiff

EPS is activated only when the driver steers the steering wheel, thus reducing energy loss compared with the hydraulics. Its modular design allows for easy assembly. EPS consists of motor, electronic control unit (ECU), torque sensor and steering gear.
bar.gif Our unique control algorithm allows for improved handling. bar.gif Compact, light weight. bar.gif Capable of controlling motors from 25 to 80A. bar.gif Standardized column integrated or stand alone ECU.Basically its a electrically power steering to assist the driver to turn the steering wheel. Check the electronic control unit(ECU) for any short/burnout and the wiring should be pliable. If not then proper amount of current is not reaching the motor.
The light can light up if there a failure of the motor or any sensor is activated when this circuit has any problem.
Get i checked & repaired from their authorized Dealer and also get a service warranty for the part replaced as per norms out there.
However repair immediately otherwse you might find the steering wheel turning in haphazard manner or it could get locked while driving! .........................................sodeep

SOURCE: power steering is hard and eps light is on

Check fluid in the system, check for the serrvo pump action , if not the system must be overhauled as there is less assistance from the pump to give the hydralic thrust.
Possible failure of pump, pump belt or hydralics.

Electronic power steering . Do you know anything about automotive electronic's ? Electronic power steering control module , sensor inputs an output control ? DTC'S - diagnostic trouble codes . Electrical testing ? Do you have a professional type scan tool to check input an output data , codes ?
Power Steering System Description and Operation (Non-Turbo)
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
Torque Sensor
The PSCM uses a torque sensor as it's main input for determining the amount of steering assist. The steering column has an input shaft, from the steering wheel to the torque sensor, and an output shaft, from the torque sensor to the steering shaft coupler. The input and output shafts are separated by a torsion bar, where the torque sensor is located. The sensor consists of a compensation coil, detecting coil and 3 detecting rings. These detecting rings have toothed edges that face each other. Detecting ring 1 is fixed to the output shaft, detecting rings 2 and 3 are fixed top the input shaft. The detecting coil is positioned around the toothed edges of detecting rings 1 and 2. As torque is applied to the steering column shaft the alignment of the teeth between detecting rings 1 and 2 changes, which causes the detecting coil signal voltage to change. The PSCM recognizes this change in signal voltage as steering column shaft torque. The compensation coil is used to compensate for changes in electrical circuit impedance due to circuit temperature changes from the electrical current and voltage levels as well as ambient temperatures for accurate torque detection.
EPS Motor
The EPS motor is a 12-volt brushed DC reversible motor with a 61-amp rating. The motor assists steering through a worm shaft and reduction gear located in the steering column housing.
Power Steering Control Module (PSCM)
The PSCM uses a combination of torque sensor inputs, vehicle speed, calculated system temperature and the steering calibration to determine the amount of steering assist. When the steering wheel is turned, the PSCM uses signal voltage from the torque sensor to detect the amount of torque being applied to the steering column shaft and the amount of current to command to the EPS motor. The PSCM receives serial data from the engine control module (ECM) to determine vehicle speed. At low speeds more assist is provided for easy turning during parking maneuvers. At high speeds, less assist is provided for improved road feel and directional stability. The PSCM nor the EPS motor are designed to handle 61 amps continuously. The PSCM will go into overload protection mode to avoid system thermal damage. In this mode the PSCM will limit the amount of current commanded to the EPS motor which reduces steering assist levels. The PSCM also chooses which steering calibration to use when the ignition is turned ON, based on the production map number stored in the BCM. The PSCM contains all 8 of the steering calibrations which are different in relation to the vehicles RPO's. The PSCM has the ability to detect malfunctions within the EPS system. Any malfunction detected will cause the IPC message center to display PWR STR (or Power Steering) warning message.

Things You'll Need

Adjustable wrench
  • Pitman arm puller
  • Torque wrench
  • Show More
    Instructions

    Park the vehicle on a level surface and make sure the front wheels are pointing straight ahead. Make sure the vehicle is in park (or in gear if you have manual transmission) and set the parking brake.

    Disconnect the pitman arm from the steering box from underneath the front of the vehicle by turning the holding bolt in a counterclockwise direction with an adjustable wrench. Place a pitman arm puller (available at auto parts stores) over the pitman arm and tighten the nut on the puller in a clockwise direction with an adjustable wrench until the pitman arm loosens from the steering box shaft. Remove the pitman arm and the puller.

    Open the hood and loosen the lock nut on top of the steering box from the engine compartment with an adjustable wrench in a counterclockwise direction.

    Place a torque wrench on the steering shaft and turn the wrench one complete turn. Make sure the torque reading is approximately 2 inch pounds. Tighten the adjusting nut on top of the steering box (it comes out of the center of the lock nut) in a clockwise direction with an adjustable wrench one half turn if the torque wrench reading is too low. Loosen the nut in a counterclockwise direction if the reading is too high.

    Rotate the steering shaft with the torque wrench again. Make adjustments to the steering box adjusting nut as described in Step 4, if needed, until the correct reading is obtained on the torque wrench.

    Make sure the steering wheel is in the straight ahead position and reattach the pitman arm to the bottom of the steering shaft on the steering box. Tighten the holding nut in a clockwise direction with an adjustable wrench until the pitman arm seats into place.

    Tighten the lock nut on top of the steering box with an adjustable wrench in a clockwise direction. Close the hood
