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 setting a DTC.

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. 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.

You should have it check for codes , may need to be reset !

SOURCE: does the 2005 pontiac grand prix have a variable steering unit?

The safest way to tell is by taking the VIN to the dealership parts department and asking them. If you know what to look for, there should be an electrical modulator valve on the PS pump or pressure line if it has variable steering.

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.

My ABS, traction control, and steering assist lights are on in my 2004 pontiac grand prix gt. The rear wheel bearing assembly was just replaced. what would cause this?


Hi, the wheel speed sensor and tone ring are built into the bearing/hub assembly. Make sure the new hub contains an ABS wheel sensor and the cable was properly connected. If it is properly connected, the new hub may be defective.
