It could well be that your HDD has died, indications thus far indicate so.

The only real fix is replacing it and re-installing your operating system however, if you can extract it and connect it to another PC, you may be able to run some diagnostic software against it to see if it can be repaired or data recovered.

Did you have the recall done on it ?
recall 05S28. Description: Speed Control Deactivation Switch.

It could be a blow fuse in the recall harness, if you did have it done.

Try the self test, and see what the results are. If you do not get it into self test mode, it could be the fuse in teh recall harness that is blown. The 1st revision of the recall harness was an inline ATM fuse, not sure if the revision 2 was the same. If that fuse is blown, the switch is leaking, and should be checked.

Self-Test Diagnostics

WARNING:
This test is a key on engine off (KOEO) test only that is conducted in park only with emergency brake fully engaged.

1. Enter self-test diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. Five additional flashes at this point indicate a defective speed control servo. Release the OFF switch.

2. Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL.

If the ON switch is not depressed within five seconds after entering the diagnostics mode, the module times out and the procedure must be started over.

The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch.

Note:
There will be a slight delay when the last button is pressed and the lamp flashes.

3. A lamp flash with the last button (SET/ACCEL) indicates that the static test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective.

If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes:

— 2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).

Remote control units have diagnostic program in the
control, after 3 to 5 minutes of operating if the diagnostic
tools detect abnormal operation, then its shutdown the unit
to protect from damage. Thermistor sensor is one of the
parts that detect the operation of the unit. Out of range
or defective thermistor can shut the operation of the unit.

If your indoor and outdoor is clean start the unit in cool mode and monitor the outdoor pipes. If your suction pipe is icing or dry then your unit is under charge, but if your suction is cold and sweating then the system is ok and sure that the thermistor sensor is defective.
- Out of range thermistor sensor in both return air and freeze up sensor can cause the tripping “off “ the unit. The resistance of both thermistor is 8 to 10k ohms, so can test by using ohm meter

Try to unplug the unit or “off” after 10sec. “on” the circuit breaker and then start the unit.
But if the defect persist then you need a qualified technician. The below error may be the cause of unit failure.
