The notes below are based on knowledge accumulated through research, P3. I do not presume to know everything there is to know about the EAS, and if I have got something incorrect please let me know through the usual channels Paul. P3. 8a at http www. AULRO. com or Paul Snr Cordwell at the Range Rover P3. Facebook https www. RRP3. 8. A PDF version of this page may be downloaded from HERE, however, this page will always be same or more up to date than the PDF version. Basics of Operation. Important stuff to note about the EAS If a door or the tailgate is open, the EAS will not adjust unless you are moving at more than 8kph If your foot is on the brake pedal, the EAS will not adjust unless you hold it for more than 3 minutes Pushing in the EAS Inhibit switch on the centre dash will prevent the car from changing height between Standard and Low height settings In automatic mode, the height of the car will drop from Standard to Low Highway height when speed is maintained above 8. It will return to Standard height when speed drops below 6. When parked and with the engine off, the car should never raise its height. It will automatically wake up every few hours to check and adjust height, but should only ever adjust down to the lowest height sensor reading. Fuses and Relays Relay RL2. MF2 3. 0 Amp Maxi fuse control power to the diaphragm solenoid and compressor. F4. 4 F2. 9 on post 9. Amp fuse which controls the EAS ECU, the valve driver pack and the pressure switch. The delay timer under the front left seat maintains power to the EAS after the ignition is switched off, and wakes it up every few hours to adjust downwards to the lowest height sensor reading. Height Sensors. These are simple potentiometers that have a 5 Volt reference voltage modified by the dial position on the sensor, and fed back to the EAS ECU. Valid readings are between 4. Adobe Pdf Sharpen Text'>Adobe Pdf Sharpen Text. These readings do not necessarily have a direct bearing on actual heights between each corner, so always use a measuring tape or similar to set correct heights. At the front, the height sensors are connected between the chassis and the radius arms. At the rear, the height sensors are connected between the chassis and the trailing arms. Air Compressor. The internal thermal sensor should cut out at approximately 1. Deg. C, allowing the system to cool down for three minutes. If the thermal switch is still tripped open path to ground after three minutes, another three minute period will start and repeat until the thermal switch path to ground is closed. Air Dryer. Potentially moist air from the compressor passes through the dryer before entering the main body of the valve block to the air lines. When exhausting from the air springs, air passes back through the dryer in the opposite direction to flush out moisture through the exhaust port on the valve block. Air TankReservoir. A 9. L air tank is mounted to the chassis roughly under the right hand seats. A single 6mm air line is used to supply and exhaust air tofrom the tank. The tank has a plug to drain accumulated moisture. Air Lines. 6mm air lines go to the air springs, and the line tofrom the tank, plus the short line between the compressor and valve block. A 4mm vent line exits the diaphragm solenoid. Valve Block Components Overview. Main components are A solenoid for each air spring to allow air in or out, operated by the driver unit aka Valve Driver A solenoid for air ingress, and one for air egressexhaust, operated by the driver unit A solenoid to operate the diaphragm which controls the direction of air flow, activated by the compressor relay A pressure switch controls operation of the compressor. Below approximately 1. A relief valve vents excess pressure inside the valve block at approximately 1. A silencer is screwed in to the smaller block to quieten exhausting air. The driver unit aka Valve Driver, the black epoxy casing at the side of the valve block controls the current to the six solenoids the diaphragm solenoid is operated by the compressor relay to give a pulsed voltage, which prevents the coils within the solenoids from burning out. Note in the diagram below, the shape of the three Non Return Valves is representative of their shape rather than function, i. DO NOT represent air flow, rather the shape of the cone end of the NRV. Air flows in the opposite direction to the arrow head, and is blocked by the o ring on the cone of the NRV. Click the image below to open it in a new window. How the Valve Block Operates. When filling the Air Tank. Click the image below to open it in a new window. When the compressor is running, the compressor relay RL2. This directs all incoming air from the compressor through the dryer via port 7 and back in to the valve block at port 5. With the inlet valve and exhaust valve closed, no air can flow tofrom the air spring solenoids, forcing all air to the tank via port 6. When the Air Springs are Inflating front left shownClick the image below to open it in a new window. Generally, the compressor will be operating when one or more springs are inflating, but it does not have to be. The diaphragm valve solenoid is open to allow air in the system to hold the diaphragm closed. The exhaust valve solenoid is closed to prevent air exiting via the diaphragm valve. The inlet valve solenoid opens to permit air from the tank port 6 or compressor to flow to whatever air spring solenoid is open. When the Air Springs are Deflating rears shownClick the image below to open it in a new window. The compressor will notshould not run when the air springs are deflating. The solenoid for each deflating bag will open to allow air back in to the valve block, and the exhaust valve will open to allow air to flow back through the dryer. With the diaphragm valve solenoid off, the diaphragm is free to lift and allow air out to atmosphere via the exhaust silencer. Frequently Asked Questions. Do my air springs equalise Yes sometimes, but just the front. When you drive off from a stop in gear, foot off the brake pedal the compressor will stop running for a few seconds to allow the front springs to equalise. Why do I get the Extended Ride Height symbol on the dash This is a design feature intended to lift the body above an obstacle which has grounded the body. In otherwise normal operation, it is usually due to a problem with a height sensor not being able to register a lowering of feedback within a 1. You should be able to manually select a lower height setting, or the Extended Ride should cancel itself within ten minutes, or speed increases above 5. Sometimes you can reset the problem by stopping the car and switching off the engine, open a door and then close it again causes an EAS check, even with the ignition off. Make sure all doors and the tailgate are closed, wait a minute and then start the engine. The only downside to this is that if it is a hard fault you may cause the car to drop to the bump stops. Why does the compressor not run at all For the compressor to operate automatically, the following conditions must be met Engine speed greater than 5. Pressure switch operational open Thermal switch closed grounded Exhaust valve solenoid closed Compressor Relay operational closed and MF2 not blown.
