P1E48 Description

The 14 V power module, also called the accessory DC power control module, constantly monitors system temperature to protect against overheat conditions. The module also monitors the function of the temperature sensors. These sensors are internal to the 14 V power module and are not serviced separately from the control module. The 14 V power module is an air cooled component. The 14 V power module vent fan is controlled by the hybrid powertrain control module 2.
