C1714

DTC C1714 LEFT REAR HEIGHT CONTROL SENSOR CIRCUIT

CIRCUIT DESCRIPTION

DTC Detecting Condition:

Inside the sensor, a brush integrated with the control sensor rotor shaft moves above the resistor, 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.

HINT:
- Once the ECU stores DTC C1713/13 or C1714/14 in the memory, vehicle height control is suspended and not carried out until a normal signal is input to the ECU from the height control sensor sub-assembly. 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-assembly 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-assembly are faulty, the suspension control ECU suspend the height control function immediately.

INSPECTION PROCEDURE

HINT:
- Proceed to troubleshooting following the flow chart, regardless of whether or not DTC C1713/13 or C1714/14 is displayed.
- If DTC C1761/61 (ECU malfunction) and/or C1774/74 (power source circuit) is displayed, perform the inspection necessary for DTC C1761/61 and/or C1774/74 first.
(If DTC C1761/61 and C1774/74 are output at the same time, perform the inspection necessary for DTC C1774/74 first.)
- Start the inspection from step 1 when using the hand-held tester, and start from step 2 when not using the hand-held tester.
