DATC Module Mercury Mountaineer II

HVAC System - Climate Control System

DATC Module

The DATC module

is located in the instrument panel.
has a vacuum fluorescent display for displaying set temperature, airflow direction, blower speed and diagnostic trouble codes (DTCs).
utilizes an on-board diagnostic (OBD) feature to supply the technician with diagnostic trouble codes (DTCs). These DTCs direct the technician to the inoperative component.
