CIRCUIT DESCRIPTION

DTC Detecting Condition:

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 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, C1712, C1713 or C1714 is output, vehicle height control is suspended.
- If the normal signal is output from the height control sensor sub-assembly while suspending vehicle height control, vehicle height control is resumed. The operation is also resumed when the ignition switch is turned off once, then turned on again.
