There are a number of conditions that will inhibit operation of the air suspension compressor. It is vitally important that these inhibits are not confused with a system malfunction. A full list of compressor inhibits is contained in the Air Suspension Control section. A temperature sensor is located within the compressor. If the compressor temperature rises above set limits, the ECU will inhibit compressor operation.
The air suspension system may be used to raise or lower the height of the vehicle, using the air suspension control switch. Note: The system may raise or lower the vehicle automatically e. Changes to the height of the vehicle must be made when all doors are closed. If a door is opened during a height change, the height change will be suspended. To raise the suspension, we will want to momentarily trigger the air valves and the compressor relay circuit.
To lower the suspension we will be activating the same corner valves in combination with the exhaust valve. This is accomplished by manually making circuit connections through the Air Suspension wiring harness.
We are emulating the normal operation of the Air Suspension computer by manually making physical wiring connections. This is a last resort operation that should only be attempted if you are stranded in the most remote off road locations with no hope of getting home without a working air suspension. It is advisable to inflate both front corners at the same time. Also the same is true for the rear. Trying to trigger individual corners is possible but it will become difficult to keep the vehicle level from left to right.
It is easiest to raise both rear corners at the same time and then raise both front corners to match. Note: Always make sure you have your 4 digit EKA code emergency key access code before disconnecting the vehicle main battery. Push-fit connections.
To remove an airline from a push-fit connection - Using a flat blade screwdriver or your fingertip lightly push inwards on the collar surrounding the airline while at the same time lightly pulling outwards on the airline. The collars on these new valves are black in colour. To insert an airline into a push-fit connection - make sure the airline is clean and not pinched, scored or deformed.
Push the airline inwards approximately 12mm you will feel a slight click. Pinched, scored or deformed airlines should be cut clean at 90 degrees with a suitable blade or Stanley knife. This image shows the location of your EAS air suspension housing.
