Air Conditioning System (For Automatic Air Conditioning System) -- System Description |
The air conditioning system has the following features:
- The air conditioning amplifier assembly is equipped with a self-diagnosis function. If there is a malfunction in the system, it stores DTCs in its memory and the air conditioning switch indicator blinks.
- The air conditioning amplifier assembly receives the vehicle speed signal from the combination meter.
- The recirculation damper servo sub-assembly, air mix damper servo sub-assembly and mode damper servo sub-assembly rely on their built-in pulse sensors to detect their respective motor rotation angles.
- The servo motor rotation angle zero point calibration is necessary in the following situations: 1) the servo motor deviates from the calibrated position, 2) the air conditioning amplifier assembly backup power source is cut, or 3) the air conditioning amplifier assembly or servo motor is replaced.
For 1, when the ignition switch is turned off, zero point calibration of the air conditioning amplifier assembly is automatically performed. For 2 and 3, when the backup power source returns and the ignition switch is turned to ON, zero point calibration of the air conditioning amplifier assembly is automatically performed.
While zero point calibration is being performed, the following occurs: 1) the DEF indicator blinks at 1 second intervals, but the air conditioning amplifier assembly other outputs are disabled; and 2) the air conditioning system switches do not function.
