P1EA9 CADILLAC Description
The 14 V power module, also called the accessory DC power control module, monitors its 14 volt circuit when it is enabled. This DTC sets when the 14 volt circuit in the 14 V power module is below this minimum level at the time it is enabled. 14V power module module functions will run only when an APM enable message from the hybrid powertrain control module is active on the serial data circuit.
