C1714
DTC C1714/14 Rear Height Control Sensor LH Circuit MalfunctionDESCRIPTION
DTC Detection Condition:
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.

INSPECTION PROCEDURE
NOTE:
- Before performing troubleshooting, inspect the connectors of related circuits.
- If DTC C1782/82 (Power Source Voltage Malfunction) is output at the same time, perform troubleshooting for C1782/82 first.
- Before replacing the suspension control ECU, perform all of the following again: 1) symptom simulation; 2) DTC inspection; and 3) intelligent tester or Techstream inspection (Data List or Active Test).If no malfunctions are found in other areas, replace the suspension control ECU.
- If the suspension control ECU or height control sensor is replaced, the vehicle height offset calibration must be performed.
