Circuit Description

Inside the sensor, a brush integrated with the control sensor rotor shaft moves above the resister, providing linear output. Since the resistance value between the brush and resistor terminal changes in proportion to the shaft rotation angle, the fixed voltage applied to the resistor by ECU is modified by the sensor and output to the ECU as a voltage indicating the shaft rotation angle.

DTC

DTC No.	DTC Detecting Condition	Trouble Area
C1713/13	With the ignition switch ON, a voltage of 4.7 V or more or 0.3 V or less at each height control sensor sub-assy rear is detected for 1 sec.	Height control sensor sub-assy rear RH Right rear height control sensor circuit Suspension control ECU
C1714/14		Height control sensor sub-assy rear LH Left rear height control sensor circuit Suspension control ECU

HINT:

Once the ECU stores DTC C1713/13 or C1714/14 in the memory, vehicle height control is suspended not carried out until a normal signal is input to the ECU from the height control sensor sub-assy. However, the control resumes if the ignition switch is once turned OFF, and then turned ON again.
When the suspension control ECU detects a malfunction in the height control sensor, the height control indicator lamp "N" comes on or blinks, and the height control switch ("HI" and "LO") is suspended.
When either one of the right or left height control sensor sub-assy is faulty, the suspension control ECU uses the other one (functioning one) to adjust the vehicle height to the normal height. When both of the height control sensor sub-assy are faulty, the suspension control ECU suspend the height control function immediately.
