Power steering is beeping at you...

I had a similar problem with a recently purchased '86. I would be driving
along when a beeping would emit from inside the dash. Soon after, my power
steering would feel more like manual. I checked my factory service manual
and discovered that the Speed Sensing Power Steering control unit, located
under the dash below the instrument panel, emits beep codes to indicate a
problem. There are six different conditions/codes:

1) 2-beeps, pause, repeat. In case abnormality occurs to the engine speed
signal. The buzzer sounds when the vehicle speed signal is input and no
engine speed signal is input (short circuit, broken wire, etc.)

2) 3-beeps, pause, repeat. In case abnormality occurs to the stepping motor
signal. The buzzer sounds when there are broken wires or short circuits
in coils or harnesses.

3) 5-beeps, pause, repeat. In case abnormality occurs to steering sensor
signal. The buzzer sounds 60-seconds after broken wire or short circuit occurs
to sensors or harnesses when the vehicle speed is above 40Km/h (25 mph.)

4) 1-beep, pause, repeat. In case abnormality occurs to speed sensor signal.
In case broken wires or short circuits occur to sensors or harnesses, the
buzzer sounds 60-seconds after the engine speed signal of 2200 rpm continues
for 18-seconds.

5) Continuous beep. In case abnormality occurs to the power steering
microcomputer. The buzzer sounds if the microcomputer becomes abnormal and
cannot control the system.

6) 4-beeps, pause, repeat. Also in case an abnormality occurs to the power
steering microcomputer. The buzzer sounds when there are circuit troubles
other than with the micro computer.

My beep code was #4 from above. I removed the control unit from my car,
opened the metal box it was in, removed the circuit board and resoldered it.
Upon re-installing, everything was fine. You might also want to first just
try removing the connector to the control unit, cleaning it, and then re-
connecting. I'm wondering if this could have fixed mine.
