Test Valve
This menu item allows manual control over valves in the EAS to raise or lower one vehicle corner or
section at a time in order to diagnose problems with the suspension.
WARNING
Care should be taken when using the test valves functions. Make
sure no objects or person are under the vehicle or near any suspen-
sion components. Keep all the doors closed. Do not try to raise the
suspension higher than its maximum travel.
Serious damage or injurie can result if the procedure is performed
improperly! GAP Diagnostic assumes no liability for damages incur-
red through use of the IIDTool.
Options for manual infl ation (+) or defl ation (-) are:
• All four corners together.
• Front, both sides together.
• Rear, both sides together.
• Front left corner.
• Front right corner.
• Rear left corner.
• Rear right corner.
When a section is infl ated, the appropriate corner valve(s) are opened along with the reservoir valve.
The suspension starts rising from the reservoir and automatically switches to the compressor after a
few seconds. There should be a noticeable decrease in the rate at which the suspension rises at this
point.
When a section is defl ated, the appropriate corner valve(s) are opened along with the exhaust valve.
The infl ation / defl ation continue as long as the button is held. The display shows the current height
(relative to the standard height) while valves are activated in order to help see the height change and
also confi rm the behavior of height sensors.
The suspension can be returned to normal operation by choosing ‘EXIT&LEAVE TEST MODE’ or
pressing the on / off button on the cruise control. If the option ‘EXIT&KEEP TEST MODE’ was chosen,
normal EAS operation must be re-enabled using the ‘Re-Enable EAS’ function (see below)..
