Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - SUSPENSION CONTROL

ACTIVE HEIGHT CONTROL SUSPENSION - ON-VEHICLE INSPECTION

1. OPERATE HEIGHT CONTROL SWITCH AND CHECK CHANGE OF VEHICLE HEIGHT
  • NOTICE:
Perform the inspection with the vehicle empty.
When operating the height control switch, operate the switch with the driver door opened, and then close the driver door after getting out of the vehicle.
  • HINT:
  • Vehicle height control starts just after closing the door.

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

For the front side, measure the ground clearance of the front adjusting cam bolt center.


For the rear side, measure the ground clearance of the rear lower control arm front side center.

  • HINT:
  • Refer to the following for the measurements ().

Start the engine.

Push the height control switch to change from "N" to "HI" mode.

Check the time required for the height change and the changed amount of the vehicle height.

  • Standard Value:
  • Vehicle ConditionFluid Temperature ConditionReference Value
    "HI" mode (Up time)20°C (68°F) +/-10°C (50°F)Approximately 15 seconds or less
  • Amount of Change in Vehicle Height:
  • ItemSpecified Condition
    FrontApproximately +50 mm (+1.97 in.)
    RearApproximately +60 mm (+2.36 in.)
  • NOTICE:
  • After vehicle height control has been completed, wait for approximately 20 seconds until the height is fixed securely, then check the changed amount of vehicle height.

Push the height control switch to change from "N" to "LO" mode.

Check the time required for the height change and the changed amount of the vehicle height.

  • Standard Value:
  • Vehicle ConditionFluid Temperature ConditionReference Value
    "LO" mode (Down time)20°C (68°F) +/-10°C (50°F)Approximately 10 seconds or less
  • Amount of Change in Vehicle Height:
  • ItemSpecified Condition
    FrontApproximately -60 mm (-2.36 in.)
    RearApproximately -40 mm (-1.57 in.)
  • NOTICE:
  • After vehicle height control has been completed, wait for approximately 20 seconds until the height is fixed securely, then check the changed amount of vehicle height.
2. INSPECT FLUID PRESSURE
  • NOTICE:
  • With the vehicle empty, perform this inspection with 1 person sitting in the driver seat in order to confirm that the switch operation and vehicle height change have been completed.
  • HINT:
  • The average weight for one person is about 55 kg (121.3 lb).

Turn the engine switch off.

Connect the intelligent tester to the DLC3.

Start the engine and turn the tester on.

Press the UP button of the height control switch. Using the Data List, check the oil pressure when the vehicle height changes from NORMAL to HI.

3. INSPECT VEHICLE SPEED SENSING FUNCTION
  • HINT:
  • When the vehicle speed sensing function control operates, nothing displays on the indicator in the combination meter.

Turn the engine switch off.

Connect the intelligent tester to the DLC3.

Turn the engine switch on (IG) and the tester on.

Using the Data List, check the vehicle speed sensing function.

When the transfer is in the L4 position:

When the vehicle is driven at a speed of approximately 3 km/h (2 mph) or more, check that the vehicle height changes to HI using the Data List.

  • OK:
  • The display changes to HI.

Using the Data List, check if the vehicle height changes from HI to L4 HI when the vehicle speed is 40 km/h (25 mph) or more.

  • OK:
  • The display changes to L4 HI.

When driving at a high speed:

Using the Data List, check that the vehicle height lowers when the vehicle height is NORMAL and the vehicle speed is 100 km/h (62 mph) or more.

  • OK:
  • The display changes to FAST LO.

Using the Data List, check that the vehicle height returns to NORMAL when the vehicle speed is reduced to less than 80 km/h (50 mph).

  • OK:
  • The display changes to NORMAL.

When vehicle height control is prohibited:

Press the height control OFF switch to prohibit vehicle height control.

Drive the vehicle at 80 km/h (50 mph) or more with the vehicle height NORMAL, or drive the vehicle at 30 km/h (19 mph) or more with the vehicle height not NORMAL and, using the Data List, check that vehicle height control prohibition is canceled.
