DTC C1711/11, C1712/12, C1713/13, C1714/14: Front Height Control Sensor RH Circuit Malfunction; Front Height Control Sensor LH Circuit Malfunction; Right Rear Height Control Sensor Circuit; Left Rear Height Control Sensor Circuit: Description
WARNING: This page is about a different car, the 2007 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
The height control sensor sub-assembly controls the resistance value by following changes in vehicle height. The suspension control ECU detects the change in vehicle height from the transformed voltage. The suspension control ECU outputs a constant voltage of 5 V to the SHB terminal of the height control sensor sub-assembly.
In the height control sensor the voltage is changed due to the resistance. The changed voltage is output from the SHFR terminal of the height control sensor sub-assembly to suspension control ECU, thus the vehicle height is detected.
HINT:
- If DTC C1711/11, C1712/12, C1713/13 or C1714/14 is output, the vehicle height control is suspended. Height control OFF switch on the combination meter assembly comes on and the vehicle height indicator "N" comes on or blink.
- If the normal signal is output from the height control sensor sub-assembly while suspending the vehicle height control, the vehicle height control is resumed. The operation is also resumed when the ignition switch is turned off once, then turned on again.
