Description
The ambient temperature sensor is installed in the front part of the condenser to detect the ambient temperature and control the air conditioner. The sensor is connected to the combination meter and detects fluctuations in the ambient temperature. This data is used for controlling the room temperature.
The sensor sends a signal to the air conditioning amplifier via the combination meter. The resistance of the ambient temperature sensor changes in accordance with the ambient temperature. As the temperature decreases, the resistance increases. As the temperature increases, the resistance decreases.
The air conditioning amplifier applies a voltage (5 v) to the ambient temperature sensor and reads voltage changes as changes in the resistance of the ambient temperature sensor. The combination meter sends the read signal to the air conditioning amplifier via can communication.

   Hint:
By reading the data list displayed on an intelligent
tester, values can be checked, including those of the
switches, sensors, and actuators, without removing any
parts. Reading the data list as the first step of
troubleshooting is one method of shortening diagnostic
time.

Different diameter tire malfunction
   
Description
The skid control ecu measures the speed of each wheel by receiving signals 
from the speed sensor.
These signals are used for recognizing that all 4 wheels are operating properly. 
Therefore, all wheel
signals must be equal.
