What is Toyota Air Conditioning Panel Initialization?
1 Answers
Toyota air conditioning panel initialization is introduced as follows: Diagnostic function: During self-diagnosis of the automatic air conditioning system, fault information can be obtained in two ways. One is to connect an intelligent tester to the vehicle's diagnostic socket (DLC3) to read system data and fault codes; the other is to simultaneously press the AUTO and REFRESH/FRESH keys on the air conditioning control panel to enter self-diagnosis mode. At this time, the air conditioning amplifier will display all fault information related to indicators, sensors, and actuators on the control panel. Even if the ignition switch is turned off, these fault messages will remain stored in the air conditioning amplifier's memory. Indicator check: After the AUTO and REFRESH/FRESH keys are triggered, the indicators will light up/extinguish at 1-second intervals, flashing 4 times before turning off, indicating normal operation of the indicators. Sensor check: The display can show sensor history and current faults. If there is more than one fault, press the A/C key to view all fault information for each sensor one by one. If checking the sunlight sensor indoors, an open circuit fault may be displayed. In this case, place the sunlight sensor under an incandescent lamp or move the vehicle outdoors for inspection.
