Why does the steering wheel locks when I try to make a left or right turn in my 2002 Lincoln LS? What is wrong when I hear a grinding noise coming from the engine when I try to make a turn?

Replace the clock spring, or check all the cabling and plugs first. If you are inexperienced take it to an auto electrician, otherwise do it yourself but disconnect the negative battery terminal for 2 minutes prior to opening the steering wheel to check the plugs, as not doing so could cause the airbag to go off. In addition you can also take out the airbag fuse. Check radio control plugs and close it up again and reconnect everything in reverse order. If that doesn't fix it, then have the clock spring replaced professionally, its too much mucking around if you don't know what you're doing.

These cars are famous for leaky seals where the valve cover interfaces with the cylinder head, at the spark plug journals. They fill with oil, short the coils and cause a misfire. Driving it any significant distance can destroy your catalytic converters ad unburnt fuel ignites therein, creating inferno-like conditions and a fire hazard too. You'll get a "300 code", such as 301 if cylinder 1 is misfiring, 302 for # 2, etc. Pull the coil off the spark plug for that cylinder and if it is moist at all, that's your issue. Have new seals put in, or you'll just keep blowing coils at $50 a whack.

If all is fine, try resetting the codes and see if it comes back again.
The flashing SRS light it called an LFC code. The reason you are getting different information is that it does not pinpoint a defective part - but that you have either a open circuit or a short.... so many things can cause this.
here are the codes:

B1932 32 8 Driver Air Bag Circuit Resistance High
B1993 36 22 Driver Side Air Bag Circuit Shorted to Ground
B1992 36 22 Driver Side Air Bag Circuit Shorted to Battery or Ignition
B1994 36 22 Driver Side Air Bag Circuit High Resistance
B1995 36 22 Driver Side Air Bag Circuit Resistance Low

Typically, a 32 is a broken or open wire, and a 36 is a short.

So that is why a 32 is usually the connector under the driver seat (to the driver position sensor in the seat) since the seat moves back and forth all the time (with easy-entry) - the wires break causing it to go 'open circuit'.
the 36 is usually a short - so when the clock-spring fails - it's actually a ribbon cable in the steering column that wear through - causing multiple wires to rub through bare and short to each-other.
but - since this is an electircal circuit - any bare wire could cause
