2004 Ford E250 4.6 V8 trouble codes

I have the above Ford with 100,000 miles. Had the following trouble codes when I first looked:
Code:
===OBDII DTC None=== 
Successful DTC reading, no error codes found 
 
Module: On Board Diagnostic II 
 
===END OBDII DTC None=== 
 
===IC DTC B1352=== 
Code: B1352 - Ignition key in circuit fault 
 
Module: Instrument Cluster 
 
Diagnostic Trouble Code details 
 
Ignition key in circuit fault 
 
--- Possible Causes -------- 
 This DTC can be generated by: 
 
-Open Key-In Ignition Switch circuit 
    - Battery short Key-In Ignition Switch circuit 
    - Battery short Ignition Switch RUN/ACCY circuit 
    - Suspect Ignition Switch 
    - Suspect Lighting Control Module. 
 
===END IC DTC B1352=== 
 
===IC DTC C1284=== 
Code: C1284 - Oil Pressure Switch Failure 
Note: This code may not be valid. Re-run the Self-Test with the vehicle running to verify the code. 
 
Module: Instrument Cluster 
 
Diagnostic Trouble Code details 
 
Oil Pressure Switch Failure 
 
Note: This code may not be valid. Re-run the Self-Test with the vehicle running to verify the code. 
 
---------------- Possible Causes ------------ 
 
 
Oil pressure switch > 1kOhms, but not open circuit. 
 
 
Suspect 
 
 
-Corroded pressure switch connector/contacts 
 
===END IC DTC C1284=== 
 
===PCM DTC P1000=== 
Code: P1000 - On-Board Diagnostic (OBD) Systems Readiness Test Not Complete 
 
Module: Powertrain Control Module 
 
Diagnostic Trouble Code details 
 
Check of all systems is not complete since last memory clear. 
 
--Possible Causes-- 
    - The vehicle is new from the factory and has not yet been through a complete OBD Drive Cycle. 
    - The battery or PCM has been disconnected. 
    - An OBD monitor failure had occurred prior to completion of an OBD Drive Cycle. 
    - The PCM DTCs have been cleared as part of a service process. 
 
Note: The only way P1000 can be cleared (removed) from memory is when all of the OBD monitors have been successfully completed during normal vehicle operation. 
 
P1000 cannot be cleared from the PCM when: 1. The thermostat is stuck open and a DTC is not generated. 2. There is an open VSS circuit and a DTC is not generated. 3. If the vehicle has a Power Take Off (PTO), the circuit is shorted to VPWR or B+, or the PTO is ON during Self-test. 
 
The purpose of the Diagnostic Trouble Code DTC P1000 is to indicate that not all of the On Board Diagnostics OBD monitors have yet been successfully completed.  You may also refer to the OBD Drive Cycle defined under the Powertrain Control/Emission Diagnosis Manual-Diagnostic Methods or the Owner's Manual. 
 
Remember: It is not necessary to remove P1000 from the Powertrain Control Module PCM by driving the vehicle. 
 
===END PCM DTC P1000=== 
 
===RCM DTC B1342=== 
Code: B1342 - ECU internal fault 
 
Module: Restraint Control Module 
 
Diagnostic Trouble Code details 
 
ECU internal fault 
 
Refer to the workshop manual for further diagnosis and repair. 
 
===END RCM DTC B1342=== 
 
===ABS DTC None=== 
Successful DTC reading, no error codes found 
 
Module: Anti-Lock Brake / Traction Control Module 
 
===END ABS DTC None===
I reset the codes, then drove for a few miles and checked again:

Code:
===OBDII DTC None=== 
Successful DTC reading, no error codes found 
 
Module: On Board Diagnostic II 
 
===END OBDII DTC None=== 
 
===IC DTC C1284=== 
Code: C1284 - Oil Pressure Switch Failure 
Note: This code may not be valid. Re-run the Self-Test with the vehicle running to verify the code.

Any ideas of what this might mean?

Sounds like weak battery or corroded terminals. Also check ground connections!

Most OBD II systems, if you clear codes, or disconnect the battery, you'll need to roll on at least 50+ miles before new codes will be read/stored.

That second read out you posted, looks almost like there were no code registered.

Are you actually trying to troubleshoot a problem, or just understand the codes? Looks like you're running a self-test, and if you don't know the proper procedure some of these codes will be set.

Is there actually something wrong here, or are you looking for something that's not broken?
