CONTROL
FORCED DEF CONTROL
When air outlet position is switched to DEF, A/C is
automatically turned ON, and outside/inside air
selection damper is set to the fresh air position to
quickly defrost the windshield screen.
MAX COOL, MAX HOT CONTROL
When the set temperature is at MAX COOL (15°C) or
at MAX HOT (29°C) with the air outlet and air volume
at the AUTO positions, the following controls are
made automatically by the A/C-ECU.

IDLE-UP CONTROL
A/C-ECU and the engine-ECU communicate with
each other through the CAN communication. The
idle-up speed of the engine is controlled in two steps
depending on the A/C load to secure the air cooling
performance during summer and to enhance fuel
economy in seasons with moderate temperature.
DETECTION CONTROL FOR
REFRIGERANT LEAKS
A/C-ECU determines if the refrigerant amount is less
than specified or refrigerant pressure is abnormal by
using the ambient temperature (ambient temperature
sensor to measure refrigerant inflation rate) and
refrigerant pressure (measured by the A/C pressure
sensor). When refrigerant amount or refrigerant pres-
sure is judged abnormal, the compressor is cut-off to
protect the A/C system.
PROTECTION CONTROL AT AIR BAG
DEPLOYMENT (DURING COLLISION)
When the air bag deployment is detected, the A/C
system is stopped.
COMMUNICATION
A/C-ECU performs the signal transmission and
reception with each ECU via CAN (Controller Area
Network)*.
NOTE: *: For details of CAN communication, refer to
−
GROUP 54C Controller Area Network P.54C-2.
DIAGNOSTIC FUNCTION
A/C-ECU has the following functions for easier sys-
tem checks.
• DIAGNOSTIC FUNCTION
• Service data output
• Actuator test
NOTE: For each item, refer to the Workshop Manual.
