Circuit/System Description

The 14V power module, often referred to as 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 14V power module and are not serviced separately from the control module.

The 14V power module is an air cooled component. The 14V power module vent fan is controlled by the hybrid/EV powertrain control module 2.
