Description and operation Description The optimal seat position set by the driver is memorized into the power seat unit by using IMS switch. In case of the position change, the seat can restore its preset position by IMS switch.
Description The A/C Pressure Transducer (APT) converts the pressure value of high pressure line into voltage value after measuring it. By converted voltage value, engine ECU controls the cooling fan by operating it high speed or low speed.
