Yes to this.. Had the same thing, however I didn't notice low volts until I swapped the pump.. So I have a good used pump if you want it.. pay shipping..Check your voltage on the DIC as well to make sure your alternator is charging properly. Mine acted the same and the alternator failed a week later. When the alternator failed, the DIC displayed "Service Power Steering" and "Battery Saver Active".
Yes that is normal, however if you do not have a lot of demand on the charging system, the computer will not call for the extra voltage. I have a new 240 amp alternator and have seen the voltage go down to 12.8 while driving normal (not WOT normal.. but normal, normal)14.5 volts is average for me according to logs.
You dont have to put the car in the air to turn the wheels lock to lock.. just make sure you are rolling, like in a parking lot. What happens when you hit the locks or have the wheel turned all the way is the system PSI will go from (normal operating) approx 125-200psi to 1300-1500 psi and this will force any air out of the system. This is the reason people have leaking steering systems, because in parking lots they crank the wheel all the way and hold it to get in an out of the parking space..Just got done driving around, and my voltage was at 14.5 and dropped down to 13.8 to 13.9 the entire trip so I'm guessing that isn't the culprit. Will turn wheel lock to lock this weekend and hopefully get some good results from that, otherwise back to the drawing board. Thanks for all the suggestions keep them coming!
