Check for pressure out of the air pump. If there, then the problem is a blown seal in the shock.

1. make sure the switch is on (under the passenger side dash board). 2. check to make sure the relay is good (black little box under the right front bumper. 3. there are two (that I know of) switches/sensors.  1 is behind the left front tire.  The other is up behind the spare tire.  Taking the spare tire off gives you tons of room to work with.  The sensors look like mini shock absorbers with black rubber and can be compressed and pulled easily by hand.  Moving those will simulate the suspension going up and down and should trigger the compressor. 4. if the compressor doesn't come on (and all the above is fine) it sounds like your compressor is bad and should be replaced.  I got one from Arnott Industries in Florida and they have been very nice to work with so far.

SOURCE: AIR SUSPENSION PROBLEMS FOR 2000 LINCOLN TOWNCAR CARTIER

I have serviced these in the past and it will probably be a combination of things. I just a few weeks ago fixed a 1999 with the same problems. Generally from past repairs, the electric pump has been working overtime to compensate for leaking rear air shocks. The best solution is to replace them both, not a cheap repair, the pump around 275.00 and each shock arount 275.00.
Just with every thing over time things fail, the rear shocks develop leaks over time/weather cracks, they are easy to check, soapy water will identify this as the problem. If you can get under it enough to spray around the bottom of the shocks when they are inflated. These systems are computer controlled and if you have the proper scanner you can check the system out for eletrical problems easily. My past experiences with these suspensions as almost always the shocks and pump.

SOURCE: 2001 audi allroad air suspension wont lower

I had the same problem, I went to my mechanic and they said that the system has shut itself off due to a problem the computer has seen, in my case it was a selinoid in the pump which released air had failed and had to be replaced, unfortonatly you can not buy the selinoid seperately and would have to replace the entire pump, I was lucky though because he has a spare pump that he pulled off another car which was blown but the selinoid was still good. It took them about 4 hours to find the problem but that was my experiance. DO NOT TAKE IT TO THE DEALER they will charge you for 4 new air bags and a new pump they quoted me almost 5000 Dollers and i got mine fixed for $500

I have a 2001 Jaguar S-Type. Suspension is out & dashboard msg reads "CATS Systems Fault". Located the ADCM, but don't see any corrosion at connectors. Could fixing be as simple as replacing the ADCM?


the adaptive damping system, adcm. is linked to the abs system. it controles the valves in the shock absorbers to make the suspension hard or soft and i think it adaptes to how you drive. you should take your car to someone with suitable diagnostic equipment to get the fault codes out of the system, the problem is more than likely one of the shock absorbers. the system defaults to hard suspension when a fault is present and puts that warning on. hope that is helpfull.

The dashborad says suspension fault


Problems with the air suspension seem to be less frequent with the Sport than in previous Range Rover models, but they still do occur. One owner reports "Whenever my RRS is lowered to "access" level a suspension system fault message apprears.". Another reports " Had the RRS back less than 2 hours and another "suspension fault." Also kept receiving messages that the vehicle is raising slowly and vehicle will raise when system cools. Couldn't even drive because it wouldn't raise out of access mode. Anyway, back to the dealer. Picked the RRS up again today-dealer said the EAS compressor was faulty and replaced it. So far everything is ok." Overall, most of the problems seem to be related to bad suspension height sensors or bad compressors. Angus Wade of the Czech Republic had his suspension light come on when in Germany; it started yellow and then red, then disappeared when he stopped and restarted the engine -- and has not happened since. His dealer said they have seen this a bit.

Weak Compressor: An official Technical Service Bulletin (TSB) LS-204-004 addresses "ELECTRONIC AIR SUSPENSION (EAS) WARNING MESSAGE AND LAMP ILLUMINATION". This deals with the warning message "Suspension Fault - Normal Height Only" message appearing with the Air Suspension Warning Lamp on. Computer diagnosis shows pressure increasing too slowly or unable to pressurize, with no air leaks. The usual problem is the compressor exhaust valve sticking, causing an internal air leak when the compressor is active. The bulletin recommends renewing the air compressor (RQG500090 is the latest specification air compressor with a stronger exhaust valve return spring)and installing and updating the air suspension control module software using WDS disc 13 or later.

Suspension Fault Message (random): One owner reported getting random suspension fault messages on his brand new RR Sport purchased in June 2006, well after the fix was in for the weak compressor. His suspension Fault message and Suspension Warning Light (Amber) came on after 5 days of ownership. He stopped and restarted the car, which caused the light and message to disappear, but they came on again after 5 minutes. Later the same day, the warnings disappeared again.

I have heard that on 2006 models, EAS fault messages can be caused by an internal leak in the Air Suspension compressor exhaust valve. The fix is said to be replacing the compressor updating the software.

Hope helps.

Air suspension out (inactive ) code



1. The automatic suspension system on a Land Rover must be placed in a service mode (High Lock) prior to raising the vehicle on a frame-contact hoist. This can only be accomplished by using a Land Rover Test Book Scan tool or an aftermarket equivalent.

2. If the suspension is allowed to hang freely at maximum extension, the suspension controller will enter a fault lockout mode and disable the compressor and height sensors

3. In addition, the suspension system will vent the suspension in an attempt to bring the vehicle to a correct ride height.

4. Since the suspension is hanging free at maximum extension, all the air will be vented, causing the vehicle to sit at maximum low when taken off the frame-contact hoist. A Land Rover Test Book Scan Tool or an equivalent is required to reset the suspension once it has entered the lockout mode.

EXPEDITION REAR AIR RIDE PROBLEM


do you have just rear air suspension? here's rear only. 4 wheel different. Deler an run a diagnostic test with WDS machine and get fault codes.
-------------------------------------------------------------------------------------
The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving conditions:
  • Ride is improved by using an air type spring (the soft ride is inherent).
  • Handling is improved by maintaining constant vehicle attitude.
The system consists of unique rear air springs, the air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for the RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines and the use of air springs with air spring solenoids.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed or the vehicle speed exceeds 16 km/h (10 mph).
----------------------------------------------------------------------------------------
Air Suspension Height Sensor
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3.2 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm (3.2 in) of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket).
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level
------------------------------------------------------------------------------
  • Uneven vehicle height
  • Circuitry.
  • Rear pneumatic fault.
  • Air compressor assembly.
  • Air suspension control module.
  • Go To Pinpoint Test I .
