The code is "Keep Alive Power Voltage Too Low" perhaps you can find something in chilton's regarding this error. Appears to be a communication error

P1633 means KAM (keep alive memory) power is low. The power that goes to the vehicles computer to hold its memory when the key is off has lost its power. I would start by checking fuses in the fuse panel in the engine compartment(near the radiator support). If the fuses are all good then I would test for power at the computer connector which is also in the engine compartment behind the engine. I don't have the pin number or wire color at the moment (I apologize) since the Ford website is down at the moment. I have repaired this problem in the past by installing another power wire to feed the circuit essentially bypassing the original circuit.
Hope this helps
