First, please, do not give someone a jump with your vehicle. Most people do not know the proper procedure to jump a vehicle with all the electronics on modern vehicles. What you think is doing someone a favor could cost you hundreds to a thousand dollars or more. When someone has a dead battery and you go to jump their battery, their dead battery and cranking their engine over, loads your charging system beyond the max your alternator can output. It can damage any electronic module that is on when you jump their car. DO NO GIVE SOMEONE A JUMP START! It's not like the old days anymore. If you insist on giving someone a jump, make sure you tell them they have to do it this way or you will not help them. Turn your engine off. Hook up your jumper cables making sure the ground cable is hooked up first on both cars. Look for a good ground not on the battery post. Then hook up the positive cable to the dead cars positive terminal. Next hook up the positive terminal or your battery. If everything goes okay and there is no problems, disconnect the positive jumper cable from your car and start your car up. Reconnect the positive jumper cable to your car and let the alternator help charge for a while. When you are ready to jump the dead car, turn your car off. Don't let the dead car draw from your running car, ever.
your battery is to start your engine. Your alternator is to run you car and charge your battery. Even though there are many alternators that can charge over 200 amps, (although most are 60 to 90) A dead car can draw over 600 amps depending on why they think they need a jump. So, they could max out your alternator's capacity, draw down your battery and the surge could blow anything that's on.
that being said, you should scan your vehicle and see what codes you have for your steering. The steering sensor may need to be re-calibrated. Module may need to be re-flashed. Module may be bad and need to be replaced. Column may need to be replaced. A scanner will let you see what is happening with the column and the steering sensor to see if it's reading anything
