Hello, You need to read system with a scanner to Find out what code is set and what component, Wiring is causing the fault. Would be best to have system read with a GM scanner.

SOURCE: what does the service variable effort steering

hi this sounds like you may need to top up the power steering fluid in the reservoir bottle, it may have got low, or the fluid is due a change..hope this helps please vote thanks

My 2006 Buick Lacrosse suddenly started pulling to the right and became very hard to steer. Then the "Charging System Failure" warning came on. What could this be?


Do you know if your vehicle has --------------------------------------------------------------------------------
Power Steering System (w/o Electro-Hydraulic Steering) or
Variable Effort Steering System
The variable effort steering (VES) system or MAGNASTEER® varies the amount of effort required to steer the vehicle as vehicle speed changes. At low speeds, the system provides minimal steering effort for easy turning and parking maneuvers. Steering effort is increased at higher speeds to provide firmer steering for increased road feel and directional stability. The electronic brake control module (EBCM) controls a bi-directional magnetic rotary actuator located in the steering rack and pinion. The EBCM varies the steering assist by adjusting the current flow through the actuator to achieve a given level of effort to steer the vehicle. The VES system accomplishes this by adding or subtracting torque on the input shaft to the rack and pinion. The main component of the system is an electromagnetic actuator, which consists of a multiple-pole ring-style permanent magnet, a pole piece, and an electromagnetic coil assembly. The VES system uses the ABS wheel speed sensor inputs to determine vehicle speed. When the EBCM senses wheel speed, it commands a current to the VES actuator that is most appropriate for each speed. The EBCM commands current from negative two amps to positive three amps to the actuator, which is polarized. At low speeds, a negative current is commanded, which assists steering. At medium speeds no current is commanded and steering is assisted by hydraulics only. At high speeds, a positive current is commanded, which creates steering resistance. Ignition voltage and ground are provided through the EBCM. The EBCM has the ability to detect malfunctions in the actuator or the circuits to the actuator. Any malfunctions detected will cause the system to ramp to zero amps and steering will be assisted by hydraulics only and set a DTC.
Are there any other lights lit on the dash ? ABS ?
DTC C0450 Steering Assist Control Solenoid/Motor/Actuator Circuit could have a diagnostic trouble code !
The electronic brake control module (EBCM) commands current from 0-1 amp to the variable effort steering (VES) actuator, depending on vehicle speed. At low speeds, 1 amp of current is commanded to the actuator and the actuator valve is fully closed. A speed increases, less current is commanded to the actuator and the valve opens, allowing pressure to bleed off through a power steering fluid orifice. The EBCM monitors and compares the Commanded and Feedback Current parameters to detect malfunctions in the VES system.
Or you could have a bad steering rack !
Charging System/Generator Fault
Refer to Charging System Description and Operation in Engine Electrical
Alternator problem maybe !
The electrical power management (EPM) system is designed to monitor and control the charging system and send diagnostic messages to alert the driver of possible problems with the battery and generator. This EPM system primarily utilizes existing on-board computer capability to maximize the effectiveness of the generator, to manage the load, improve battery state-of-charge (SOC) and life, and minimize the system's impact on fuel economy. The EPM system performs 3 basic functions:
• It monitors the battery voltage and estimates the battery condition.
• It takes corrective actions by adjusting the regulated voltage.
• It performs diagnostics and driver notification.

I just put hub bearings on my 2005 grand Prix GTP and when I plug the sensor it says service variable effort steering what's wrong.


check the sensor on top of the steering rack ,their is a sensor that increases the idle when the steering is turned when the vehicle is stationary

Why does my 2005 pontiac grand prix say service variable effort steerin, traction control off, and service abs?


jack up the four points of the vehicle one at a time shake the tire up to down and left to right, you have bad hub assemblies which tells you your ABS IS BAD take it from there and see what lights disappear, keep me posted and we will go from there.

4 service lights come on and when they do I loose those functions . abs traction stability variable effort steering and some times the display for the radio flickers and becomes jumbled


Well-- your done for now

Stop using it--- & get it checked for codes
& have the vehicle diagnosed to find a problem
& you appear to have many

Battery any good -you tested it?

Variable Effort Steering System Description and Operation
The Variable Effort Steering (VES) system or MAGNASTEER® Varies the amount of effort required to steer the vehicle as vehicle speed changes. At low speeds, the system provides minimal steering effort for easy turning and parking Maneuvers. Steering effort is increased at higher speeds to provide firmer steering (road feel) and directional stability. The Electronic Brake Control Module (EBCM) controls a bi-directional magnetic rotary actuator located in the steering rack and pinion.

Any malfunctions detected will cause the system to ramp to zero amps and steering will be assisted by hydraulics only and setting a DTC.

The Magnasteer® system is a speed-dependent power steering system. The Magnasteer® system provides power assist at varying levels depending on need.
A bi-directional magnetic rotary actuator in the steering gear adjusts the amount of torque (driver effort) necessary to turn the steering wheel.
The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
The amount of adjustment will be directly related to the vehicle speed. The controller receives speed-related input signals from the vehicle speed sensor.
For more information on Magnasteer® refer to Variable Effort Steering System Description and Operation

Is the vehicle driveable ? The steering wheel is connected to the wheels

DTC C0450 Steering Assist Control Solenoid/Motor/Actuator Circuit
Sounds like it's stuck on full assist .

Hello, The (service ps mesage) usually accurs w/ the power steering presure switch failes or wire chaffs against the rear manafold heat shield. the ps presure switch is located in the high side line and reacts w/ the ac system.(cuts compressor operation durring hard turns) its usuall in the rear twards the fire wall down by the rack and pinnion.the wires usually rub through on the rack heat shield and set the illuminated mesage.hope this helps. thanks
