DTC P0601-41: Internal Control Module Memory Check Sum Error: General Description
WARNING: This page is about a different car, the 2022 Kia Seltos. However, it is still accessible from the selected car via links, so may be relevant.
The TCM randomly monitors memory checksum by performing a self-test. These tests are implemented to verify that all of the vehicle software operational calculations are operating properly. If the test fails due to incorrect checksum, the TCM determines there is a checksum value error.
