Evaporator Temperature Sensor Circuit (B1413/13)
DESCRIPTION
The evaporator temperature sensor is installed on the evaporator in the air conditioning
unit to detect the cooled air temperature that has passed through the evaporator
and to control the air conditioning. It sends appropriate signals to the ...
Only Wireless Control Function is Inoperative
DESCRIPTION
The door control receiver receives signals from the transmitter and sends these
signals to the main body ECU. The main body ECU then controls all doors by sending
lock/unlock signals to each door, and sends hazard flasher relay signals to the ...
