Error Code P0603

Question

Hello,
I received an error code P0603 Internal Control Module Keep Alive Memory
I am pretty sure it's because I removed the battery to replace it.
Consequently, the check engine light is on. Is there a way i can reset that error?

Thank you in advace

HI there

It is very possible the issue is because of the battery swap. You should be able to clear the code with a code reader, then if it comes back you may need to do a reprogramming on the ecm.
