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 (FROM 08/2009): Description
The height control sensor changes its resistance value based on changes in vehicle height. The suspension control ECU outputs a fixed voltage of 5 V to the height control sensor's SHB terminal. If the sensor's resistance value changes, the sensor's voltage value changes accordingly. The suspension control ECU then inputs the voltage value from the sensor to detect the vehicle height change.
