The Keep Alive Power (KAPWR) provides a constant voltage input independent of the ignition switch state to the Powertrain Control Module (PCM). This voltage is used by the PCM to maintain the Keep Alive Memory (KAM). The Diagnostic Trouble Code (DTC) indicates that the Keep Alive Power circuit has experienced a power interrupt.
