The power steering control module monitors the temperature of the Power Steering System. The power steering
control module uses voltage, current levels and input from an internal temperature sensor to calculate an
estimated system temperature. If the power steering control module detects a high system temperature event is
occurring, the amount of assist is decreased to reduce system temperature, in effort to prevent thermal damage
to the power steering components.

Conditions for Running the DTC

 Ignition ON, engine Running.

 Power steering system voltage is 9-16 volts.
 Repetitive steering input applied.
 2013 Chevrolet Cruze

Circuit/System Description

The power steering control module monitors the steering angle sensor signal via the GMLAN serial data circuit.
The power steering control module utilizes this signal to determine a center point for Active Return and Soft
End Stops. Upon detecting an invalid steering angle sensor signal, the power steering control module will
disable Active Return and Soft End Stops, then set a DTC.

NOTE: To most drivers the loss of Active Return and Soft End Stops may not be
noticeable as there is no visual indicator activated on the instrument cluster or
driver information display.

There is no diagnosable cause with the power steering control module when
this DTC is set, DO NOT REPLACE POWER STEERING CONTROL MODULE OR
STEERING GEAR DUE TO THIS DTC.

For diagnosis of an invalid steering angle sensor signal, refer to DTC C0710 also diagnosis in Antilock Brake
System.

Conditions for Running the DTC

Ignition ON

Conditions for Setting the DTC

The power steering control module has received on of the following serial data messages listed below from the
external steering angle sensor.
 2013 Chevrolet Cruze
2013 STEERING Power Steering - Cruze

 Steering angle range is exceeded

 Steering angle sensor is not calibrated
 Steering angle sensor is initialized
 Steering angle sensor message: Roll Counter is INVALID
 Steering angle sensor message: Present Bit is FALSE (not common)
 Steering angle sensor message: Error Flag is set to TRUE

Action Taken When the DTC Sets

 The electronic brake control module disables the stability control for the duration of the ignition cycle.
 Active Return and Software End Stops are deactivated.

Conditions for Clearing the DTC

 A current DTC clears when the diagnostic runs and passes.

 When the steering angle sensor signal becomes valid, the fault will set to History and can be cleared with
a scan tool.

Diagnostic Aids

The car should not pull in either direction causing the steering wheel to be OFF center while driving straight
ahead on a level surface.

gear housing and seated against the steering stop.
3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
4. If there is not a good location for the GE-8001 dial indicator pointer at the steering gear housing, install a
large worm gear hose clamp (3) to the steering gear housing over the larger steering gear boot clamp and
align the clamp so that the screw can be a location for the GE-8001 dial indicator pointer.
5. Install the GE-8001 dial indicator between the inner tie rod and the steering gear housing or the worm
gear clamp in such a way as to measure the lash between the inner tie rod and the steering gear housing.
The lash between the inner tie rod and the steering gear housing is equal to the lash between the inner tie
rod and the inner tie rod housing because the inner tie rod housing is inside the steering gear housing
during this procedure.

DESCRIPTION AND OPERATION

POWER STEERING SYSTEM DESCRIPTION AND OPERATION (HYDRAULIC POWER
STEERING)

The hydraulic power steering pump is a constant displacement vane-type pump that provides hydraulic pressure
and flow for the power steering gear. The hydraulic power steering pumps are either belt-driven or direct-drive,
cam-driven.

The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering
pump or remotely located. The following locations are typical locations for the remote reservoir:

 Mounted to the front of the dash panel

 Mounted to the inner fender
 Mounted to a bracket on the engine

The 2 basic types of power steering gears are listed below:

 A recirculating ball system

 A rack and pinion system

In the recirculating ball system, a worm gear converts steering wheel movement to movement of a sector shaft.
A pitman arm attached to the bottom of the sector shaft actually moves one tie rod and an intermediate rod
 2013 Chevrolet Cruze
2013 STEERING Power Steering - Cruze

move the other tie rod.

In the rack and pinion system, the rack and the pinion are the 2 components that convert steering wheel rotation
to lateral movement. The steering shaft is attached to the pinion in the steering gear. The pinion rotates with the
steering wheel. Gear teeth on the pinion mesh with the gear teeth on the rack. The rotating pinion moves the
rack from side to side. The lateral action of the rack pushes and pulls the tie rods in order to change the
direction of the vehicle's front wheels.

The power steering pressure hose connects the power steering pump union fitting to the power steering gear and
allows pressurized power steering fluid to flow from the pump to the gear.

The power steering return hose returns fluid from the power steering gear back to the power steering fluid
reservoir. The power steering return line may contain an integral fin-type or line-type power steering fluid
cooler.

In a typical power steering system, a pump generates hydraulic pressure, causing fluid to flow, via the pressure
hose, to the steering gear valve assembly. The steering gear valve assembly regulates the incoming fluid to the
right and left chambers in order to assist in right and left turns.

Turning the steering wheel activates the valve assembly, which applies greater fluid pressure and flow to one
side of the steering gear piston, and lower pressure and flow to the other side of the piston. The pressure assists
the movement of the gear piston. Tie rods transfer this force to the front wheels, which turn the vehicle right or
left.

POWER STEERING SYSTEM DESCRIPTION AND OPERATION (ELECTRONIC POWER

STEERING)

The power steering system consists of the following components:

 The power steering control module

 The power steering motor
 The power steering motor rotational sensor
 The torque sensor
 The steering gear (rack and dual pinion)

The rack and dual pinion electric power steering system reduces the amount of effort needed to steer the vehicle
utilizing the power steering control module to control the power steering motor to maneuver the steering gear.
The power steering control module also uses a combination of the torque sensor, motor rotational sensor,
battery voltage circuit and GMLAN serial data circuit to perform the system functions. The power steering
control module monitors vehicle speed and engine speed from the engine control module via the GMLAN serial
data circuit to determine the amount of steering assist needed to steer the vehicle. At low speeds more assist is
provided for easy turning during parking maneuvers. At higher speeds less assist is provided for improved road
feel and directional stability.

The power steering control module uses a combination of the torque sensor, motor rotational sensor, vehicle
speed, and calculated system temperature inputs to determine the amount of assist needed. The power steering
control module continuously monitors the digital torque sensor's torque and index current signals. As the
 2013 Chevrolet Cruze
2013 STEERING Power Steering - Cruze

steering wheel is turned and torsional twist is applied to the steering shaft, the steering input and output shafts
are monitored via the torque signal circuit and then processed by the power steering control module to calculate
the steering torque. The voltage signals of the motor position sensor and the digital torque sensor's index current
signal are both processed by the power steering control module to detect and calculate the steering wheel angle.

The power steering control module responds to the change in the digital torque sensor signals as well as the
motor rotational sensor's voltage signals by commanding current to the power steering motor. The power
steering control module controls the pulse width modulated motor drive circuit to drive the 3-phase motor. The
power steering control module and motor assembly is attached to the base of the steering gear housing and
assists the steering gear pinion to maneuver the rack from left to right according to turning the steering wheel.

The power steering control module has the ability to calculate an internal system temperature to protect the
power steering system from damage caused by high temperature. To reduce a high system temperature, the
power steering control module will reduce the amount of current commanded to the power steering motor,
which reduces the amount of steering assist. The power steering control module has the ability to detect
malfunctions within the electric power steering system. Any malfunction detected that disables steering assist
will cause the SERVICE POWER STEERING message to be displayed on the driver information center.

DESCRIPTION AND OPERATION

STEERING WHEEL AND COLUMN DESCRIPTION AND OPERATION

The steering wheel and column has 4 primary functions:

 Vehicle steering
 Vehicle security
 Driver convenience
 Driver safety

Vehicle Steering

The steering wheel is the first link between the driver and the vehicle. The steering wheel is fastened to a
steering shaft within the column. At the lower end of the column, the intermediate shaft connects the column to
the steering gear.

Vehicle Security, Found on Some Vehicle Models

Theft deterrent components are mounted and designed into the steering column. The following components
allow the column to be locked in order to minimize theft:

 The ignition switch-location varies

 The steering column lock-content varies
 The ignition cylinder-location varies
 The theft deterrent module-location varies

Driver Convenience

The steering wheel and column may also have driver controls attached for convenience and comfort. The
following controls may be mounted on or near the steering wheel or column.
 2013 Chevrolet Cruze
2013 STEERING Steering Wheel and Column - Cruze

 The turn signal switch

 The hazard switch
 The headlamp dimmer switch
 The wiper/washer switch
 The horn pad/cruise control switch
 The redundant radio/entertainment system controls
 The manual/power tilt or tilt/telescoping functions
 The power pedal adjustment control switch
 The navigation
 The HVAC controls

Driver Safety

The steering wheel and column has safety features to protect the driver. The following components may be
mounted on or near the steering column:

Energy-Absorbing Steering Column

The energy-absorbing steering column compresses in the event of a front-end collision, which reduces the
chance of injury to the driver. The energy-absorbing feature, collapsible steering shaft, and break away
mounting features help reduce the injury in the event of an accident. In addition to these features, the
following driver safety features may be on the steering column:

SIR Coil and Module

For additional information on the operation of the SIR coil and module, refer to Supplemental Inflatable
Restraint System Description and Operation .

Steering Wheel Angle Sensor or Steering Wheel Position Sensor

The steering wheel position sensor is located somewhere along the steering shaft assembly. The sensor
measures the position of the steering wheel and the speed at which it is rotated. A signal representing this
measurement is provided to the vehicle stability enhancement system (VSES) module. The VSES module
uses this signal, along with several others representing different vehicle conditions, to monitor the driving
behavior of the vehicle and ensure that it stays in control. If the VSES module determines that the vehicle
is out of control it provides signals to the powertrain control module (PCM) and the ABS module. These
output signals are used to modulate the transmission torque and brake pressure of each of the vehicles
wheels in order to regain control of the vehicle.
