Component Location[Front Seat Heater (Non-Air ventilation)]1. Seat heater unit (Passenger seat only)2. Seat chusion heater3. Seat back (Heater)[Front Seat Heater (Air ventilation)]1.
InspectionFront Seat Heater1.Check for continuity and measure the resistance between terminals No 3 and No 6. Standard value Driver / Assists (cushion + back) : 1.
DescriptionThe In-car air temperature sensor is built in the heater & A/C control unit.The sensor contains a thermistor which measures the temperature of the inside. The signal decided by the resistance value which changes in accordance with perceived inside temperature, is delivered to heater control unit and according to this signal the contr
Inspection1.Check the resistance of the ambient temperature sensor between terminals 1 and 2 whether it changes by changing the ambient temperature.1. Ambient Sensor (+)2. Sensor groundSpecification Ambient temperature [°C (°F)] Resistance between terminal 1 and 2 (
