Hello. You can give it a try by diconncting the battery. If it does give you problems again, then you need to go to a well know junkyard that have good condition cars and items. Look for the same cars as yours and get both the ecm and pcm.

Failed ecm p0603


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 ?

2004 Ford F-250 6.0 liter diesel loosing coolant


i'm getting "internal control module keep alive memory?" for fault p0603. which i think has nothing to do with using coolant. i assume you're finding no leaks, so it's leaking somewhere you can't see. does it smell of antifreeze in the interior? is the carpet wet? the heater core might be leaking into the interior. there could be a slow leak on the top of the engine and it's boiling away before it has a chance to pool. fill your reservoir fully. let the engine get hot. inspect for steam in the engine compartment.
