DTC B1004: Keep Alive Memory: Description

Keep Alive Memory (KAM) is a data storage area in module which can save pertinent data when ignition is turned off. KAM is lost if battery power is removed from module. DTC will set when power or ground is removed from module while module is awake. When DTC is set, module reverts to base programmed operating data until new data is learned and stored in KAM.
