I'm not sure what you mean by kam. I never heard of such a thing, but if your computer is losing it's memory (like a battery disconnect) try getting your battery tested. I've seen a few where the battery was weak or had a dead cell and when the motor is cranked the voltage drops low enough that it resets the pcm memory.

Trouble shooting P0603 for 98 aurora is this why

Code P0603 means that the PCM's Keep Alive Memory (KAM) self test is failing. This is a routine self test that is performed periodically through out the day. This is critical because the PCM's Keep Alive Memory Modules store all of the PCM's adaptive calculations that need to be 'kept alive' or saved when the vehicle isn't operating. If this part of the PCM's functionality is unreliable, the powertrain's main computer can't be trusted to accurately do its job and may need to be replaced.

Check engine code 512

KAM is keep alive memory. check your battery and see if it is holing enough voltage to keep the memory. If not odds are your pcm is on the way out.

How to clear code 118 and 224 on 1994 ranger

Ford Ranger/Explorer/Mountaineer 1991-1999
Clearing Codes



These codes are retained in memory for 40 warm-up cycles. To clear the codes for the purposes of testing or confirming repair, perform the code reading procedure. When the fault codes begin to be displayed, de-activate the test by either disconnecting the jumper wire (meter, MIL or message center) or releasing the test button on the hand scanner. Stopping the test during code transmission will erase the Continuous Memory. Do not disconnect the negative battery cable to clear these codes; the Keep Alive memory will be cleared and a new code, 19, will be stored for loss of PCM power.


The Keep Alive Memory (KAM) contains the adaptive factors used by the processor to compensate for component tolerances and wear. It should not be routinely cleared during diagnosis. If an emissions related part is replaced during repair, the KAM must be cleared. Failure to clear the KAM may cause severe driveability problems since the correction factor for the old component will be applied to the new component.
To clear the Keep Alive Memory, disconnect the negative battery cable for at least 5 minutes. After the memory is cleared and the battery reconnected, the vehicle must be driven at least 10 miles so that the processor may relearn the needed correction factors. The distance to be driven depends on the engine and vehicle, but all drives should include steady-throttle cruise on open roads. Certain driveability problems may be noted during the drive because the adaptive factors are not yet functioning

I lost the battery connection while connecting new radio and cant find battery wire

I would like to help you, but I am at a small disadvantage here....
You lost WHAT battery connection? WHAT battery wire are you looking for? Do you mean the Keep Alive Memory (KAM) and the ignition (IGN) battery feed at the radio harness connector? Do you think you may have "lost" the battery feed due to blowing a fuse during trying to wire the new radio?

Kam voltage

The Keep Alive Memory (KAM) voltage to the onboard computer has been interrupted. Either by a dead battery (for whatever reason) a disconnected battery, sombody pulled the fuse out of the fuse block, or there is a bad connection in the circuit leading to the computer.

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.

Where is the kam fuse on 1999 f250

it's be the pcm or computer fuse, if you've cleared a code and just need to reset the kam or keep alive memory. disconnect the battery for more than 1 minute but no more than 3 minutes

04 f150 code p1633

I looked up the code you posted, and came back as kam (keep alive memory).It's a series of battery powered memory locations in the computor which allows it to store input failures identified during normal operation for use in later diagnostic routines.KAM even adopts some calibration parameters to compensate for changes in the vehicle system The only way that I know of to fix it is replace the computor, but have it checked out first. Hope this helped.

If it is not passing because monitor is not completed and there are no trouble codes.
Start from cold engine with no more than 3/4 tank of fuel and more than 1/4. Drive it about 25 miles with at least 2 minutes of steady speeds between 35-45 mph and also the same at 50-65 mph.Then make several stop and goes,pausing about 20-30 sec when stopped.
If you turn the engine off before the monitors complete you must go thru a 6 hour cool down cycle before it will try and complete again. Then stop by an Autozone or some place that checks codes for free and have them check it and make sure no codes are stored in memory and the P1000 code has cleared. If it has cleared you should be good to go then. Plus this will make sure that it is not an issue with their inspection machine linking up with your vehicle. The only other problem it may be is if you are loosing the keep alive memory when you shut down your vehicle.That would be fuse 19 (15amp) in the underhood fuse panel.
