NOTE:
The Body Control Module (BCM) may also be referred as Platform Zone Module (PZM).
The Electronic Climate Control (ECC) system automatically regulates and maintains selected in-vehicle temperature between 65°F (18°C) and 85°F (29°C) regardless of changes in outside air temperature. Settings of 60°F (16°C) and 90°F (32°C) provide unregulated cooling and heating, respectively. The Climate Control Panel (CCP) is the main control for selecting in-vehicle comfort levels. See Fig 1 or Fig 2 .
Main components of ECC system are A/C-Heater Programmer (ACM), Powertrain Control Module (PCM), refrigerant system, temperature sensors, and Heating, Ventilation, and Air Conditioning (HVAC) module.
