This can only be done on Range Rover 2002-2005. All other vehicles can have the standard height changed only which is the reference point for all other height modes. For example, if the standard height is increased by 10 mm (Menu->Height->Adjust All), all other height modes, Offroad, Access and Highway height, will also be 10 [...]
In other words, the feedback received by the suspension ECU suggests an incongruity between actions and reactions. The first thing to verify is each height sensor calibration (consult the user manual). This may also be caused by a bad sensor or wiring.
Or, can the IIDTool help when the suspension becomes inoperative? Can it close any specific valve for any corner and keep it closed while you limp off the trail? Yes. For example, when an air strut fails, the suspension ECU detects a major fault since it is not able to raise the corner. In some cases, it [...]
Use the height function to raise the standard height which is the reference point for all other height modes. IIDTool Menu->Height... you can adjust by increment/decrement of 1 mm. Keep in mind that a 1 mm increase in the ECU will be a bit more at the wheel because of the sensors non linearity and [...]
The IIDTool saves the calibration values which are constant and not dependent on the surface.
If a vehicle hoist is to be used: Raise the vehicle using the hoist until all wheels have left the ground. Use the appropriate deflate function found in the service test menu. You can now proceed with replacing the strut*. Re-Enable the EAS ECU using your IIDTool (consult the user manual for more details). If the work [...]
Actually, only the first part of the statement is accurate: more air, yes. Higher pressure, no. Only the volume is increased or decreased (spring diameter assumed to remain constant). The effective spring rate is relatively constant over the whole suspension height range. The element that does come into play and affect the suspension behavior (comfort…) [...]
This is not currently available. It may be done in the future depending on how easy/difficult it is to implement. For safety reasons, we will limit the speed maximum increment. For example, from stock 50 km/h to 60 km/h.
Both the EASControl and IIDTool rewrite the target height values of the EAS ECU. Once completed, the unit is disconnected. Do not leave the tool permanently connected.
This is caused by the sensors output curve non linearity. The further away from the central point, the higher the difference. We recommend measuring after each height changes to validate.
