DTC C1711/11, C1712/12, C1713/13: Front Height Control Sensor RH Circuit Malfunction; Front Height Control Sensor LH Circuit Malfunction; Rear Height Control Sensor Circuit Malfunction: Description
WARNING: This page is about a different car, the 2006 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
Inside each sensor, a brush integrated with the control sensor rotor shaft moves above the resistor, providing linear output. The resistance value between the brush and resistor terminal changes in proportion to the shaft rotation angle, so the fixed voltage applied to the resistor by the ECU is modified by the sensor and output to the ECU as a voltage indication the shaft rotation angle.
DTC DETECTION CONDITION TABLE
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1711/11 | When the following condition is consisting and the abnormal signal continued for 1 sec. at the vehicle speed 8 km/h (5 mph) or more: Detecting the abnormal signal (Height control sensor terminal voltage of ECU is 0.3 V or less or 4.7 V or more) for every 0.01 sec. and that continued for 0.2 sec. |
|
| C1712/12 | When the following condition is consisting and the abnormal signal continued for 1 sec. at the vehicle speed 8 km/h (5 mph) or more: Detecting the abnormal signal (Height control sensor terminal voltage of ECU is 0.3 V or less or 4.7 V or more) for every 0.01 sec. and that continued for 0.2 sec. |
|
| C1713/13 | When the following condition is consisting and the abnormal signal continued for 1 sec. at the vehicle speed 8 km/h (5 mph) or more: Detecting the abnormal signal (Height control sensor terminal voltage of ECU is 0.3 V or less or 4.7 V or more) for every 0.01 sec. and that continued for 0.2 sec. |

HINT:
- DTC C1711/11 corresponds to the right front height control sensor circuit.
- DTC C1712/12 corresponds to the left front height control sensor circuit.
- DTC C1713/13 corresponds to the rear height control sensor circuit.
Fail-safe function:
If a trouble occurs in the height control sensor circuit, the height control is prohibited after the ECU has adjusted the vehicle height to the standard (fluid pressure correspond to the standard height).
