What Does P0603 Code Mean on 7.3L Powerstroke?<\/h2>\n\n\n\n

P0603 is one of the most common trouble codes of Ford’s 7.3L engine. By definition, the code P0603 means Internal Control Module Keep Alive Memory (KAM) Error.<\/p>\n\n\n\n

The Keep-Alive Memory (KAM) acts like an Artificial Intelligence (AI) that learns from every drive cycle & it includes engine settings you change while driving on different types of road. Later on, these data are used by the PCM. <\/p>\n\n\n\n

The PCM tries to retrieve data from Keep Alive Memory (KAM) to give optimal performance according to the user’s preferences. When it fails to do so even after several attempts, it generates the error code P0603. <\/p>\n\n\n\n

Interesting Fact:<\/strong> The KAM is a special kind of RAM that stores data permanently as the battery directly powers it.<\/p>\n\n\n\n
