HAC-26 < SYSTEM DESCRIPTION > [AUTOMATIC AIR CONDITIONING] SYSTEM REAR AUTOMATIC AIR CONDITIONING SYSTEM : System Description INFOID:0000000009652518 SYSTEM DIAGRAM DESCRIPTION • Rear automatic air conditioning system is controlled by each function of A/C auto amp. auto amp.) and rear A/C control. CONTROL BY A/C AUTO AMP. • HAC-27, "REAR AUTOMATIC AIR CONDITIONING SYSTEM : Temperature Control" • HAC-27, "REAR AUTOMATIC AIR CONDITIONING SYSTEM : Air Outlet Control" • HAC-27, "REAR AUTOMATIC AIR CONDITIONING SYSTEM : Air Flow Control" • HAC-19, "FRONT AUTOMATIC AIR CONDITIONING SYSTEM : Air Inlet Control" • HAC-29, "REAR AUTOMATIC AIR CONDITIONING SYSTEM : Door Control" • Correction for input value Ambient temperature correction - A/C auto amp. inputs the temperature detected by ambient sensor as the ambient temperature. ing control. - A/C auto amp. selects and uses the initial value of ambient temperature data depending on the engine cool- ant temperature when turning the ignition switch from OFF to ON. The detection temperature of the ambient ° C (133 ° F)]. The mem- ory data (before the ignition switch is OFF) when the engine is warmed up [approximately 56 ° C (133 ° F) or more]. - The correction of the ambient temperature is not performed when the detection temperature of the ambient temperature is less than approximately − 20 ° C (–4 ° F). Rear in-vehicle temperature correction - A/C auto amp. inputs the temperature detected by rear in-vehicle sensor as the rear in-vehicle temperature. ditioning control. - A/C auto amp. performs the correction so that the recognition passenger room temperature (rear side) changes depending on the difference between the detected passenger room temperature (rear side) and the Intake temperature correction - A/C auto amp. inputs the temperature detected by intake sensor as the intake temperature (front evaporator temperature). - A/C auto amp. performs the correction of the temperature detected by intake sensor for rear air conditioning control.
