Rear suspension will deflate but why won't it inflate?


That could work , You mite be able to test the sensor in question with ohm meter . Test the front one an see what the resistance is ,then check the back one. I don't know what it should be with out looking it up in the service info . You could also check to see if the sensor is getting power from the control module , an see if there is a return input to the module .
There are a few DTC'S this able to set !

C1230 code


It is a wire that looks like a spark plug wire coming from the back side of the wheel and is attached by one or two bolts on the sensor unit. Normally on the driver side.

C1102 & c1230, I have these codes on my 1999 Explorer Sport. I would like to know where I can get pictures of where they are located.


this is an abs code. it means your rear abs sensor is bad. it is right in the middle of the rear axel on the top. it has wires going to it and looks like a little box

Suspencion light fault in the range rover sport 2006


If the suspension is "hanging" on any wheel there is a sensor that detects it. Also if a shock absorber is not maintaining pressure it will show a suspension fault...Check it out!

Truck tries to level higher on driver side than passenger side


You most likely have a bad suspension height sensor. you will need a scanner that can read the data from the suspension module to find out which one. Otherwise, there is no way to know if the driver side sensor is saying that the suspension is lower than it is (which would cause the suspension to pump up more on that side) or if the right side sensor is saying that it is higher than it really is (which would cause the right side to stop pumping up too soon).

Also, chances are pretty good that if you scan your suspension module, there will be a fault code set that will TELL you which sensor is bad. If no codes are present, you will have to test your sensors and compare the data from the sensors with the specifications for the vehicle.

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.

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
------------------------------------------------------------------------------
