DESCRIPTION

These diagnostics apply to internal microprocessor integrity conditions within the engine control module (ECM).

P0601 CONTROL MODULE MEMORY

This DTC will set if the ECM is not programmed correctly, which does NOT infer that the ECM is at fault. The engine may not start if the ECM is or was not programmed correctly.
