DTC C1711: Front Height Control Sensor RH Circuit Malfunction; DTC C1712: Front Height Control Sensor LH Circuit Malfunction; DTC C1713: Rear Height Control Sensor RH Circuit Malfunction; DTC C1714: Rear Height Control Sensor LH Circuit Malfunction [10/2017 - 10/2020]: Description

The height control sensor sub-assembly changes the resistance according to the change in vehicle height. The absorber control ECU outputs a fixed voltage of 5 V to the height control sensor sub-assembly SHB terminal. If the sensor's resistance value changes, the sensor's voltage changes accordingly. The suspension ECU then inputs the voltage value from the sensor to detect the vehicle height change.
