off when the ignition is turned off it will be off when the engine is restarted, etc.
-
computer logic that provides variable air recirculation under high temperature and humidity conditions. Because recirculation is generally
accompanied by increased fan noise, the proportion of recirculated to outside air gradually approaches full recirculation over a broad temperature
range.
The A/C-heater control for the ATC single zone front and rear heating-A/C system is diagnosed using a scan tool.
The A/C-heater control cannot be repaired or adjusted and must be replaced if found inoperative or damaged. The illumination lamps (13) and the
wiper/wash control knob are available for service replacement.
The A/C-heater control utilizes integrated circuitry and information carried on the controller area network (CAN) B bus to monitor many sensors and
switch inputs throughout the vehicle. In response to those inputs, the internal circuitry and programming of the A/C-heater control allows it to control
electronic functions and features of the ATC heating-A/C system.
The inputs received by the A/C-heater control of the ATC heating-A/C system on the CAN B bus are as follows:
-
Dimming
-
Refrigerant Pressure
-
Vehicle Identification Number
-
Vehicle Odometer
-
Engine Coolant Temperature
-
Ambient Air Temperature
-
Infrared Temperature Sensor
-
Ignition Voltage
-
Vehicle Speed
The messages broadcasted by the A/C-heater control of the ATC heating-A/C system on the CAN B bus are as follows:
-
A/C Request
-
A/C Select
-
Rear Window Defogger (EBL) Request
-
Rear Washer Request
