P0603 Internal Control Module Keep Alive Memory (KAM) Error

Trying to help a friend here. 5gen ZL1 heavily modded. Just installed new CAI with meth ports. Keeps getting this KAM code. Only way he can clear it is to hook up another battery in parallel and start car. Code is gone. He bought new battery but didnít fix issue. Thinking heís got a drain or loose connection on something. Maybe too high of an electrical draw? Bad ECM? Running out of ideas. Any help greatly appreciated.

Did he do a read or write with hp tuners with battery charger on ? Or did he copy over a file from another car I've seen that corrupt the throttle tables section or corrupt ecu.
