Instead of guessing as to what the problem is or expecting someone on here having a magical fix , take it to a qualified repair shop. Before assuming the worst an wanting to condem the PCM - powertrain control module . Will a scan tool communicate with it ? If your pulling codes it is .
DTC P0603 Control Module Long Term Memory Reset
The PCM has a memory area where it stores certain data it needs to save when the key is turned OFF. This area is called Keep Alive Memory. This diagnostic test monitors the PCM's keep alive memory for a loss or unintended change of data. If such a condition occurs, DTC P0603 will set.
Diagnostic Aids
If the battery has been disconnected for any reason DTC P0603 will set. The PCM keeps a running check on the memory; if memory changes it resets. An intermittent loss of power or ground to the PCM will cause a reset.
Have you disconnected the battery ?

The icp sensor connector is a weak link in this mess. Check and make sure that it is not broken or has loose wires or wires that are broken inside the insulation.
P1211 Injector Control Pressure Sensor Above / Below DesiredP1249 Wastegate Control Valve Performance P1211
We all know that this code is commonly caused by "Hot Chips" that are demanding more Injection Control Pressure (ICP) than the High Pressure Oil Pump can deliver. For what it's worth, these are the exact parameters that trigger this code:
ICP 410psi Higher Than Desired for 7 Seconds
ICP 280psi Lower Than Desired for 7 Seconds
This code can also be caused by legitimate High Pressure Oil System issues. Below is a list of some of the causes:
Failed or Sticking IPR (Injection Pressure Regulator)
Failed or Weak HPOP (High Pressure Oil Pump)
Any Leak in High Pressure Oil System (o-ring, stuck injector, etc.)
Low Fuel Pressure (Rare)
P1249 it is the HPOP, above or below pressure, if you have added a performance chip to your vehicle , you will get this code from time to time, basically its Turbo over boost
if your using a generic code reader like from the local auto parts store, they won't retirieve powerstroke specific codes.
P1249 is wastegate control valve performance
P0475 is exhaust pressure control valve
P0603 is KAM (keep alive memory) error
Your truck has a back pressure valve that will close to aid in the warm up of the engine. Exhaust back pressure valve can stick and give the P0475. The P1249 might be related. If your disconnecting the battery to clear the codes that's where your getting the P0603. Your turbo need to come out and the back pressure valve ooked at..it's in the turbo pedestal.
the 1211 is [injector control pressure sensor above / below desired] the 1249 is[wastegate control valve performance] check the wastegate for proper operation valve not sticking proper lube no leaks or cracked lines and check the wiring and connections to the injector control pressure sensor
p1211=ICP Not Controllable-regulates oil to Injectors
p1249=Wastegate Fail Steady State Rate
p1280=ICP Circuit Out Of Range
All but p1249 deal with your High Pressure oil system that controls your injectors
This code means the ICP pressure is aove or below specs meaing there is
a high pressure oil concern. You need to monitor the ICP with a scan
tool and see which it is. If its high then its most likely a faulty IPR
valve. If its low then its most likely a internal leak at the pump or
stand pipes.
For P0603 :-
The code P0603 is in ost case set due to the performance chip. If equipped, remove and recheck operation.
If the vehicle is not equipped with a chip, or removing it makes no
difference, monitor the voltage on fuse #22 in the interior fuse panel
to see if the battery voltage goes away when the problem occurs.
If the voltage on fuse #22 is dropping or going away, check for a loose
terminal connection on the PCM power relay. Also try swapping the PCM
power relay with a similar part to eliminate a faulty relay.
If the relay is OK, but the voltage on fuse 22 is dropping, suspect an internal problem with the interior fuse panel.
You May need to Use The Old Ignition Lock & Key ,Due to the Chip In the Key.
Circuit Description
The PCM has a memory area where it stores certain data it needs to save when the key is turned OFF. This area is called Keep Alive Memory. This diagnostic test monitors the PCM's keep alive memory for a loss or unintended change of data. If such a condition occurs, DTC P0603 will set.
Conditions for Setting the DTC
Test Condition
Test continuously.
Failure Condition
Keep alive memory checksum does not match previous checksum.
Action Taken When the DTC Sets
Clear all keep alive memory locations.
The Malfunction Indicator Lamp (MIL) will not illuminate.
No message will be displayed.
Conditions for Clearing the DTC
A History DTC will clear after forty consecutive warm-up cycles with no failures of any non-emission related diagnostic test.
A Last Test Failed (current) DTC will clear when the diagnostic runs and does not fail.
If the battery has been disconnected for any reason DTC P0603 will set. The PCM keeps a running check on the memory; if memory changes it resets. An intermittent loss of power or ground to the PCM will cause a reset.
P1249 does NOT appear in any of my charts or troubleshooting information. The codes in the P1200 section are for fuel delivery/mixture.
Are you sure that code P1249 was present?
It is unlikely that an engine trouble code on a Powerstroke would affect the transmission operation. R, 1 and 2 are manually selectable gears. If your trans won't shift into 3rd(direct) when in Drive, there may be a problem with the direct clutches and/or sprag clutch. This is a big problem area with your series of transmission. How many transmisions have you gone through so far? I've known quite a few people who have gone through 3 or 4 transmissions before the truck ever hit 60K miles, especially the 2001's. There are many updates available for your transmision and the Ford dealer may not know about a lot of them because they are strictly aftermarket, and they work!
