Suspension slow lift - Suspension fault - system cool down

ECAS fuse 1 30amp location - under hood fuse box. Is the vehicle 4WD ? 4WD fuse 48 15 amp . - location rear fuse box . Does the air inflator switch flash quickly ? Do you know what code's are ?
Diagnostic Trouble Code (DTC) Displaying
The Air Suspension system has an internal clock to prevent overheating if the compressor assembly is running for a prolonged period of time. If the system overheats, all leveling function stops until the system cools down. During this time, the indicator LED on the air inflator switch will be quickly flashing at a constant rate.
The other three diagnostic trouble codes are displayed with a blink code on the inflator switch LED. The Air Suspension Compressor Assembly shall begin to indicate the code when the condition to cause the code becomes current.
The number of the fault code shall be represented by the number of flashing pulses on the inflator switch LED. The flashing pulses shall have a repetition rate of 0.5 seconds and each code shall be separated by a 3.0 second delay. All codes shall be flashed in the order of occurrence of the fault. The blink code shall take priority over other processes that have access to the inflator switch LED. Refer to the following:
• DTC 001
• DTC 002
• DTC 003

DTC 001 System Disabled Information Stored

The air suspension compressor assembly monitors the calibrations in the electrically erasable programmable read-only memory (EEPROM). The module also monitors the compressor, solenoids and internal wiring for faults.

Fuse Block - Rear
Beneath the left rear seat

Could be that you just have a bad sensor on that side they need to be replaced I don't know if there is anybody that can check the sensor itself that is usually the cheapest place to start in that situation

Air Suspension ??????

Air Suspension Description and Operation
Air Suspension
The primary mission of the Air Suspension System is the following for the rear suspension under loaded and unloaded conditions:
• Keep the vehicle visually level
• Provide optimal headlight aiming
• Maintain optimal ride height
The Air Suspension System consists of the following items:
• Air suspension compressor assembly
• Air suspension sensors
• Rear air springs
Important: The Air Suspension System must have a voltage supply of at least 12.6V to operate properly.
The Air Suspension System will maintain the rear D height within 4 mm (0.15 in) in all loading conditions and the leveling function will deactivate if the vehicle is overloaded. The side to side D height variation is maintained within 8 mm (0.31 in). After ignition is turned off, the air suspension control module (ASCM) will remain active for between 30 minutes and 2 1/2 hours. The system will exhaust pressure within 30 minutes after the ignition is turned off to lower the vehicle after unloading. In a temperature-controlled environment, the leakage of the complete load leveling system will not result in more than 1.4 mm (0.05 in) drop of rear suspension height at GVWR during a 24 hour period. If the outdoor temperature drops from +20°C (+68°F) to -5°C (+23°F), the rear D height may drop as much as 25 mm (1 in). However, the Air Suspension System should return to the specified D height when the ignition is again cycled to ON.

What is the problem ?

Trim Height Uneven or Low ??????

The system has a ride control module (computer) you must take it to the Rolls dealer service dept and have the systems control and monitoring computer memory read to see what fault code or codes are stored for the light you say you see on come on while driving. Once the code is read a technician using special equipment will perform the appropriate diagnostics and repair the cause of the problem.

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.

Welcome to Fixya

Air suspension is currently in fault mode. It will have to be re-set by someone who has the Land Rover scantool (either a dealer or an independent shop). The EAS system is inaccessible with a regular OBDII scantool. The car will not allow you to control the suspension height (raise/lower/defeat) until the fault is cleared. Please see this link .

Thank you for using Fixya!

Hi!

Your vehicle is equiped with a small compressor that pumps air into either a bag or shock absorber, each one has a leveling mechanism that sends the signal to pump more air to that particular side. This keeps your vehicle leveled at all times, like when you have passangers in the back sit, passenger sit, or luggage.

The message you are getting means that either the air is not getting to the front passenger suspension to level it up, which could be due to an air leak, or the bag or the part of the suspension that lifts that part of the vehicle is defective.

You can get a diagnostic at any reputable suspension shop at no charge to find out the exact cause.

Good Luck!! Don't forget to rate this post!!
