The interface adapter assembly (IAA) module is a
low voltage multi-function module that manages the
following functions:
• instrument cluster functions
• power steering pump operation
• climate control system
• high voltage to low voltage conversion
• vacuum pump operation
The IAA module communicates with the traction
inverter module (TIM) and the battery controller
module (BCM) to support the instrument cluster
operation and to determine when to close the high
voltage auxiliary contactor.
The positive temperature coefficient (PTC)
switching module provides high voltage to the PTC
heater. Driver demands for heat are received by the
IAA module, which commands the PTC switching
module to operate the PTC heater. The PTC
switching module can vary output to operate the
PTC heater at either a low or high setting.
