The KAM (Keep Alive Memory) is located in the PCM (Powertrain Control Module) and stores data regarding the operating cycles. It is also worth mentioning that this memory varies according to the driving inputs and the sensor inputs. In case the car battery is disconnected, the KAM memory is cleared and the PCM (Powertrain Control Module), this happens because it uses the included learned parameters to run the engine and not the learned values according to driving habits. It remains in standby mode because each powertrain control unit has a learning module where all the vehicle driving data, information about fuel consumption, and engine performance is stored. If the control box constantly loses power, the DTC code P0603 OBD2 is set.
