2. Connect NGS Tester to the Data Link Connector (DLC).
3. Select the proper vehicle year, model, and engine type.
4. Select 4WAS-AIR SUSP/EVO (4x2 and 4x4) module.
5. Select "Parameter Reset Command (Clear Ride Height) under Active Command Modes" menu, and trigger through the warning messages and reset (trigger from OFF to ON):
- NGS version 10.0 - "Front" and "Rear".
- NGS version 11.0+ - "Front CLR".

6. Back out torsion bar adjustment bolt (approximately 40 mm from bolt head to bottom surface of torsion bar adjuster).
7. Deflate front air shocks by using NGS "Vent Front" command in "Air Suspension Control" menu (should take about 30 seconds), and jounce the front of the vehicle to fully lower the front of the vehicle.
8. Adjust and measure the vehicle ride height.
9. Once mechanical ride height is set, select "Save Calibration Values (Store Ride Height)" NGS command to calibrate the air suspension control module. Trigger through warning message(s) and save "FRONT" (trigger from OFF to ON).
