Connect a hose to the bleeder plug for the height control accumulator and loosen the bleeder plug.

Land Cruiser URJ200 URJ202 GRJ200 VDJ200 SUSPENSION CONTROL

This circuit supplies the power source to the suspension control ECU.

The multi-information display in the combination meter displays the vehicle height, the state of the height control OFF switch, and system malfunctions. To display items, the multi-information display uses CAN communication between the combination meter and suspension control ECU via the gateway ECU.

Set the tires to the specified tire pressure, and adjust all 4 wheels.

In order to decrease roll angle/pitch angle, the suspension control ECU turns the spring rate switching valve in the front suspension control valve off/on to change the fluid lines when the acceleration sensor or yaw rate sensor signal is input into the suspension control ECU. Normally, the spring rate switching valve is open.

The suspension control ECU receives signals from the ECM, four wheel drive control ECU, skid control ECU, yaw rate sensor, steering sensor, steering control ECU and main body ECU via CAN communication. When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.

This is the height control system main switch. When the height control switch is pushed, the height control OFF indicator light lights up and height control turns off.

The off condition of the height control will not be canceled until the height control switch is pushed again or the vehicle is driven.

This circuit sends a signal to the suspension control ECU in order to adjust the height to the selected height by the height control switch.

This circuit is used for sending the signal to the suspension control ECU to switch to the damping mode selected by the damping force control switch.
