Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The 14V power module, often referred to as the accessory DC power control module, converts the high voltage (360V) direct current (DC) to low voltage (14V) DC to charge the 12V battery and to operate the power accessories. The ECM controls the 14V power module by supplying a 5V pulse width modulated (PWM) signal through a control circuit. The ECM monitors 12V battery voltage to ensure the 14V power module is maintaining the desired voltage.
