Scan Tool Operating Instructions - AK Automotive Training

Manufacturer Applications
Pre-test conditions:
• The ignition must be ON;
• An approved battery charger must be connected to ensure consistent power
supply.
NOTE: The vehicle will lower during deflation of the air suspension. To avoid damage,
ensure all doors are closed.
WARNING: It is the responsibility of the technician to ensure that air has been
fully expelled from the air suspension system even if the OmiCheck indicates
that the routine has completed successfully. The procedure may need to be run
more than once to ensure all air is expelled from the system. Failure to do so
may result in personal injury.
Exit Deflate Mode
After the work has been completed the technician must re-enable the system using
the ‘Exit Deflate Mode’ option to restore normal operation of the air suspension
system.
Air Suspension System (EHC2)
• Range Rover (L322) (2002 - 2006)
There are four functions available via the OmiCheck for the EHC2 air suspension
system.
• Actuators
• Set Operating Mode
• Set Tolerance Control Mode
• Deflation Routines
Actuators
There are a number of actuators available on the OmiCheck. These are split into two
different sections.
Level Selection
The OmiCheck can be used to force the air suspension system to any level as an
alternative to using the ride height switch inside the vehicle.
• Access Level.
• Motorway Level.
• Standard Level.
• Off-road Level.
These are useful for the diagnosis of faults with the ride height switch and wiring.
