My Honda Accord 09 keeps giving hard start. Diagnosed wit p0603 kam error.

code p 0603 refers to engine control module (ECM)--Kam error==causes --ECM
it also refers to system voltage ---malfunction===causes ---wiring,-- poor connections-- battery---alternator
before you race out to get an ECM unit have the following done
have a load test done on the battery
have an accredited auto electrician check out the alternator and regulator
check the drive belt for condition and tension
check the plugs connected to the ECM have no moisture or corrosion present
check the battery terminals and battery posts are shiny clean and tight
What the code is referring to is insufficient voltage to work the ECM properly then a possible ECM fault

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.

Internal Control Module Keep Alive Memory (KAM)

P0603 means Internal Control Module Keep Alive Memory (KAM) Error

In other words, that code is set when the PCM loses "keep alive" memory B+.

This code can also be set if the batteries went dead at some point, but mainly it means there is an open circuit detected in the KAM circuit.

On a '97 F-250, check for a 5 amp fuse blown in fuse cavity #2. If the fuse is blown, check for and repair the short-to-ground in circuit #729 (red with white coloured wire).

Good luck dear.
