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.

I have a ford f 250 with dtc code p0606, Internal Ctrl Mod Kam Error, what is wrong and how do I correct or fix


There is no P0606? P0602, P0603 or P0605. P0603 KAM interrupt can be a blown fuse or low battery, P0605 can be aftermarket chip / programing or PCM failure (diesels do have a reprogram for false P0605). P0602 is usually a PCM failure.

P1211 and P0603 codes have come on after installing superchip


Hi,

For P1211 :-

This code means the ICP pressure is aove or below specs meaing there is a high pressure oil concern. You need to monitor the ICP with a scan tool and see which it is. If its high then its most likely a faulty IPR valve. If its low then its most likely a internal leak at the pump or stand pipes.

For P0603 :-

The code P0603 is in ost case set due to the performance chip.
If equipped, remove and recheck operation.

If the vehicle is not equipped with a chip, or removing it makes no difference, monitor the voltage on fuse #22 in the interior fuse panel to see if the battery voltage goes away when the problem occurs.

If the voltage on fuse #22 is dropping or going away, check for a loose terminal connection on the PCM power relay. Also try swapping the PCM power relay with a similar part to eliminate a faulty relay.

If the relay is OK, but the voltage on fuse 22 is dropping, suspect an internal problem with the interior fuse panel.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

REPLACED STEERING COLUM


You May need to Use The Old Ignition Lock & Key ,Due to the Chip In the Key.


Circuit Description

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.

Conditions for Setting the DTC

Test Condition


Test continuously.

Failure Condition

Keep alive memory checksum does not match previous checksum.

Action Taken When the DTC Sets

  • Clear all keep alive memory locations.
  • The Malfunction Indicator Lamp (MIL) will not illuminate.
  • No message will be displayed.
Conditions for Clearing the DTC

  • A History DTC will clear after forty consecutive warm-up cycles with no failures of any non-emission related diagnostic test.
  • A Last Test Failed (current) DTC will clear when the diagnostic runs and does not fail.
  • PCM battery voltage is interrupted.
  • Using a Scan tool.
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.
