Removal of the Stock Front Air Struts

1. Raise and support the vehicle.

CAUTION: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.

2. Remove the tire.

3. If you have access to a Diagnostic Computer that is capable of depressurizing the air spring, you can do that now.

4. Remove the bottom bolt. (See Figure #1 & Figure #2)

5. At this point the Shock Removal Instructions from Land Rover direct you to remove the plastic wheel well shroud from the vehicle. Our technical staff at Atlantic British has been able to remove the parts without removing the shroud. If you are having difficulty accessing the top mount nuts, you will need to remove this shroud.

6. Remove 3 top nuts supporting the weight of the assembly, so too much stress is not placed on the air supply line. (See Figures #3, #4, & #5)

7. If you did not depressurize the air spring in step # 3 above, you can do it now. While continuing to support the weight of the Spring / Shock assembly, SLOWLY loosen the nut securing the air supply line to the air spring. As you loosen the nut, you will eventually hear the air begin to escape from the spring. Proceed with even more caution at this point letting the air escape slowly. It is dangerous to allow the pressure from the air spring to violently force the fitting out of place.

8. Maneuver shock assembly out from under vehicle.

9. Disconnect the electrical connectors from all four height sensors and wire tie them to prevent contact with any moving components.

Part II - Front & Rear Coil Spring / Shock Installation

BACK TO TABLE OF CONTENTS

1. Remove Brake Calipers to allow more room for installation of shock. (See Figures #6 & #7)

2. Carefully observe the pattern of the top mount studs on the Coil Spring / Shock assembly, and observe the corresponding pattern of the mounting on the upper bracket. (See Figure #8)

3. Maneuver the assembly into place and loosely secure with the 3 each M10x1.50mm Serrated Flange Nuts. Observe the alignment of the bottom mounting eye of the shock. If it is not aligned with the bracket, you will need to remove the assembly, compress the spring and adjust for the alignment. (See Figures #9 & #10)

4. Align the bottom mounting ring with the bracket in the lower arm. You might need to move the arm up or down to get the holes to align. Slide the bolt into place and tighten the nut to 200 Nm (221 lb.ft.). (See Figures #11, #12, & #13)

EAS Re Flash Device

Caution: To understand the different modes of operation and to become familiar with the signals that the module will provide, it is important that you read through these instructions before beginning the suspension configuration.

Introduction

This Quick Reference Guide provides the information you need to configure applicable vehicles for either 4 Corner Coil Spring Suspension or 4 Corner Air Suspension using the Atlantic British Air Suspension Configuration Device. Please ensure that the device is applicable to your vehicle before attempting the configuration process.

General Overview

The Atlantic British Air Suspension Configuration Device configures a vehicle by connecting to the diagnostic socket and updating the settings stored in a number of Electronic Control Units (ECUs).

The device has two modes of operation:

  • 1. Configure the vehicle for 4 Corner Coil Springs.
  • 2. Configure the vehicle for 4 Corner Air Suspension.

IMPORTANT! The device will automatically store the Vehicle Identification Number (VIN) of the first vehicle that it is connected to. It will then be permanently locked to that vehicle.

Device Overview

Before You Start:

  • Ensure that the battery is fully charged.
  • Ensure the vehicle is in Park / Neutral with the Parking Brake applied.
  • It is recommended that the headlights are turned off throughout the configuration process.
  • Do not start the engine at any point during the configuration process.
  • Do not open or close any doors during the configuration process.
  • Locate the Diagnostic Connector (ODBII). (See Figures 1 & 2).
  • Plug the #7980 device into the Diagnostic socket. (See Figure 3).

General Operation

Power Up

The device powers up automatically when it is inserted into the vehicles diagnostic socket.

When the device powers up it will emit two short tones and flash the orange LED rapidly. A series of checks will then be performed to ensure that the configuration process can commence.

If these checks pass the device will emit a further 3 short tones before becoming silent and flashing the orange and green LEDs alternately twice a second. The device is now ready to configure the vehicle.

If the checks do not pass the sounder will emit a continuous on / off tone and the LEDs will flash alternately.

Refer to the Troubleshooting section (See Table #2) for help in diagnosing the reason for the failure.

Selecting a Mode of Operation

Both modes of operation are accessed using the 'mode selection button' located at the rear of the device.

In order to select the mode of operation you must hold this button down for a set period of time until the sounder emits a tone indicating that the required mode has been activated. The mode button can then be released to commence the configuration process.

Table #1 below describes how to select the operating modes using this button.

Table #1

Mode
Action
Coil Spring Configuration

Press and hold the mode selection button for 3 seconds until a single long tone is emitted.

 

Air Suspension Configuration
Continue to hold the mode selection button down for a further 3 seconds until 2 long tones are emitted.
Cancel
Continue to hold the mode selection button down for a further 3 seconds until 3 long tones are emitted.

If the button is held down continuously the device will cycle through the modes until it is released.

During Operation

Once a mode of operation has been selected the configuration process will commence automatically.

In order to configure the vehicle the device must reprogram a number of ECUs, perform a complete vehicle reset and clear all fault codes.

During this process a number of interior / warning lights may flash and faults may be logged. This is normal and can usually be ignored.

Throughout configuration the device will emit one long tone per second and flash one of the LEDs once per second (green for coil spring mode, orange for air suspension mode). The entire process should last approximately 1 minute.

If configuration is successful, the device will emit one long tone per second and flash the orange and green LEDs alternately.

If configuration fails the device will emit 2 long tones per second and the orange and green LEDs will flash alternately twice per second.

Once the reconfiguration operation has completed the ignition must be cycled twice to clear any error messages logged during the process.

Identifying Configured Mode

It is possible to identify the mode the vehicle is currently configured to by observing the height adjustment indicator light located next to the height adjustment button.

  • 1. Insert the ignition key and turn the ignition on (position II).
  • 2. Wait for the vehicle self checks to complete (approx. 30 seconds).

If the vehicle is configured for 4 Corner Air Suspension the height adjustment indicator light will be illuminated.

If the vehicle is configures for 4 Corner Coil Springs the height adjustment indicator light will not be illuminated.

Configuration Procedure

1. Double check that the parking brake is applied, then insert the ignition key and turn the ignition on (position II).

2. Wait for the vehicle self checks to complete (approx. 30 seconds).

3. Plug the configuration device into the diagnostic socket, ensuring that you are not holding down the mode selection button.

4. Wait for the device to power up and indicate that it is ready to configure the vehicle. (See "Power Up" Section).

5. Select the required mode of operation. (See Table #1).

6. Wait for the device to complete the configuration process and indicate that it was successful.

7. Remove the configuration device from the diagnostic socket.

8. Turn the ignition off and remove the ignition key.

9. Wait for 30 seconds.

10. Insert the ignition key and turn the ignition on (position II).

11. Wait for the vehicle self checks to complete (approx. 30 seconds).

12. Repeat steps 8, 9, 10 and 11.

13. The configuration process is now complete and all faults should have been cleared.

PLEASE NOTE: While the successful completion of the Re-Flash will eliminate any and all error messages from the Instrument Pack display, the "Air Suspension Warning Indicator" will be illuminated as seen in Figure #4.
