C1712

DTC C1711/11 Front Height Control Sensor RH Circuit Malfunction
DTC C1712/12 Front Height Control Sensor LH Circuit Malfunction
DTC C1713/13 Rear Height Control Sensor Circuit Malfunction

DESCRIPTION





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

HINT:
^ DTC C1711/11 corresponds to the front height control sensor RH circuit.
^ DTC C1712/12 corresponds to the front height control sensor LH 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).

Wiring Diagram:





HINT: When using the intelligent tester, start from *1. When not using the intelligent tester, start from *2.
