Description of ESP ESP recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle by wheel-individual braking and engine control intervention.
Description and operation 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.
Inspection 1. Turn the ignition switch ON. 2. Manually operate the control switch and measure the voltage of the blower motor. 3. Select the control switch to raise the voltage until it reaches high speed.
