If all is assembled correctly and the system is bled by working the steering from lock-to-lock several times with the engine running and topping up the reservoir as required, the power steering should work. A pressure test would prove whether the pump is working correctly.
On later CAN-bus controlled cars the electronics might need telling the steering has been repaired or replaced before it will work satisfactorily.
A control module ! Electronics
The steering column has a tilt/telescoping control system that consists of an electronic control module capable of class 2 serial data communication, a steering column power assembly with positioning motor and sensor, and a steering column control switch. The multi-function lever provides for the control of the headlamp high beams, and the windshield washer and wiper.
The tilt/telescoping steering column in/out/up/down switch is an input to the driver position module (DPM). The tilt/telescoping drive motor is an output function of the DPM.
Steering column memory settings are stored in the DPM. The steering column position sensor is an internal part of the tilt/telescoping motor assemblies, and is an input to the DPM. The DPM uses the position sensor input when storing and recalling memory settings.
Same thing with the seats , electronic control module .
Battery positive voltage is supplied at all times to the memory seat module (MSM) through the battery positive voltage circuit from the POWER SEATS circuit breaker located instrument panel (I/P) fuse block. This voltage is used to power up MSM and also to apply power to the seat motors when commanded. Battery positive voltage from the TILT/TELE SW/MEM SEAT MOD fuse located in the body control module (BCM) fuse block that supplies voltage to the seat adjuster switch and the memory function switch, also supplies voltage to the MSM. The MSM monitors this voltage circuit in order to determine if battery voltage is supplied to the seat adjuster switch. The MSM is grounded through the module ground circuit and G301.
Body Control Module (BCM)
RH footwell, mounted to the toe board, behind the carpet
It could be or the steering rack . The power steering system uses a CII type power steering pump (3A674) and a power rack and pinion steering gear.
If you never replaced either of these parts before suggest you take to a ASE certified repair shop .
Pump Flow and Pressure Tests
Before performing pump flow and pressure test, complete the following checks for conditions which could cause loss of power assist. Take corrective action if necessary.
Check power steering oil reservoir (3A697) for proper fluid level.
Check tires for correct air pressure.
Check drive belt (8620) for proper tension.
Check power steering pump (3A674) for correct model and vehicle application.
Check for correct size power steering pump pulleys (3A733) on power steering pump and engine.
Check entire system for damage. Replace parts, if necessary.
If the above items are correct, or have been corrected, and the loss of assist still exists, test power steering pump flow and pressure to determine whether the trouble is in the power steering pump , power rack and pinion steering gear or hoses.
If you can't find a power steering fluid reservoir under the hood in the engine compartment your G6 could have Electronic Power Steering . If you look up under the dash below the steering column you will see a electric motor mounted to the steering column !
The power steering system reduces the amount of effort needed to steer the vehicle. The system uses the powertrain control module (PCM), body control module (BCM), power steering control module (PSCM), discrete battery voltage supply circuit, steering shaft torque sensor, steering wheel position sensor, power steering motor, driver information center (DIC), and the serial data circuit to perform the system functions. The PSCM and the power steering motor are serviced as an assembly and are serviced separately from the steering column assembly. The steering shaft torque sensor and the steering wheel position sensor are not serviced separately from each other or from the steering column assembly. The steering column assembly does not include the power steering motor and module assembly.
Hi Anthony, I assume your question is 'How long is a dipstick?' If so the answer is the same for 'How long is a piece of string?'. 'However long it needs to be'. The length of a dipstick isn't significant. The markings etched into the dipstick close to the lower end enable you to gauge whether the volume of oil in the reservoir is sufficient to enable proper functioning of the system whether it be the power steering, transmission or engine.
Sorry but your not going to get it fxed fast ! Your vehicle has Electric Power Steering (EPS) , an electronic control module makes it work . If this module is bad an need's replacing your going to have to take it to a GM dealer to have it replaced an programmed .
The Electric Power Steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the power steering control module (PSCM), torque sensor, power steering motor rotational sensor, power steering motor, discrete battery voltage supply circuit, and the GMLAN serial data circuit to perform the system functions. The PSCM and power steering motor are each serviced separately from the steering column assembly. However, the motor rotational sensor is serviced as part of the power steering motor, and the torque sensor is serviced as part of the steering column assembly. The PSCM also monitors vehicle speed from the engine control module (ECM) via the GMLAN serial data circuit. 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.
Could have DTC'S - diagnostic trouble code's stored , need a professional scan tool to see these code's .
In most cases Automatic Fluid (ATF) is used as hydraulic fluid for power steering systems, so, yes, they are the same fluid. To identify the origin of your leak, place some sheets of news paper under the front of the car and see where the oil drops collect. Look above that and identify whether it is nearer the transmission or the power steering system. You may also be able to see the origin of the leak from beneath the car with the front raised on ramps (not jacks).
Hello and welcome to Fixya!
There are two kinds of power steering nowadays. First is the conventional power steering which requires power steering fluid. If you are lacking steering fluid it will be hard to turn.
Second is the electronic power steering. I strongly suggest that you take it in to a reputable mechanic to check and replace necessary parts for this will need an on hand trouble shooting.
Hope this helps and thank you for using Fixya! Have a good one!
