96 ford windstar KAM-(keep alive memory) circuit wire color codes to PCM clips-(3)

The code 512 indicates the PCM has experienced a power interrupt in its Keep Alive Memory (KAM) circuit and your fuel pump is controlled by the ground switching signal from the PCM (computer) to the Fuel pump relay

Keep Alive Memory code is usually set when the battery is low/bad or disconnected.

Ford Taurus model???
this is for ford T 2000
p1633 keep alive memory test failure

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.

P0603 - GM Type Powertrain - Computer and Auxiliary Outputs - ISO/SAE Controlled Description Control Module Long Term Memory Reset Conditions
Cause DTC P0604 not set, key on, then the PCM determined that its calculated checksum that did not match a previous checksum • Refer to code repair chart for instructions on how to replace a PCM and how to reprogram the replacement

CONTINUOUS MEMORY 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.

KEEP ALIVE MEMORY

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

youronboard computer system must be programed by the dealer. there is a "glitch" in software that makes so pcm does not retain the drive cycle. go to any Ford dealer and request to have the PCM updated to the latest calibration and that WILL do the trick. When New York went to the light enhanced emission inspection, we had to program hubdreds of focus' to make pass insepction...there will be a charge for this service as your vehicle would be out of warrnaty by time...shoudl be around $100 depending upon labo rates at shop....

keep alive memory power to pcm cylinder 2 injector circuit low

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.

Rate this.

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
