Warnings

Tools required

Parts

• Air suspension compressor assembly × 1 — Use OEM specification
• Air compressor mounting hardware kit × 1 — Use OEM specification
• Air line quick-connect O-rings × 4 — Use OEM specification
• Electrical connector seal × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Chock rear wheels to prevent vehicle movement
3. Connect Rivian diagnostic scanner and document any existing suspension fault codes
4. Use the diagnostic scanner to enter 'Air Suspension Service Mode' to depressurize the system
5. Disconnect the 12V auxiliary battery using the battery disconnect tool per Rivian HV safety procedures
6. Wait minimum 5 minutes for system capacitors to discharge
7. Verify high voltage system is disabled by checking the instrument cluster isolation status
8. Raise vehicle using approved lift points and support on jack stands at all four corners
9. Remove driver-side rear wheel for improved access to compressor location
10. Remove driver-side rear inner fender liner using panel removal tools

Procedure

1. 1

   Access air suspension compressor
   Locate the air suspension compressor mounted in the driver-side rear quarter panel area behind the wheel well. Remove the protective cover by releasing the three T30 Torx fasteners. Note the routing of electrical wiring and air lines before proceeding.
2. 2

   Disconnect electrical connector
   Press the locking tab on the compressor electrical connector and carefully pull the connector straight away from the compressor. Inspect the connector pins for corrosion or damage. If connector shows signs of moisture intrusion, replace the electrical connector seal.
3. 3

   Label and disconnect air supply lines
   Identify and label the four air lines connected to the compressor: main supply line, left front, right front, and rear axle distribution lines. Press the quick-connect release collar on each fitting while pulling the air line straight out. You may hear residual air escape. Place clean rags over the open ports to prevent contamination.
4. 4

   Remove compressor relay and fuse
   Locate the dedicated air suspension compressor relay and fuse in the auxiliary fuse box mounted near the compressor. Remove the relay by pulling straight up, then remove the fuse. Label these components to ensure correct reinstallation.
5. 5

   Disconnect compressor mounting bracket
   Remove the two 13mm bolts securing the compressor lower mounting bracket to the chassis rail. Support the compressor weight while removing these fasteners as the compressor assembly weighs approximately 15 pounds.
6. 6

   Remove upper mounting hardware
   Remove the three 10mm bolts securing the compressor upper mounting bracket to the body. Carefully lower the compressor assembly while ensuring no wiring or air lines are still connected. Maneuver the compressor out through the wheel well opening.
7. 7

   Inspect removed compressor and mounting area
   Examine the removed compressor for signs of physical damage, oil contamination, or moisture intrusion at the air intake filter. Check mounting brackets for cracks or deformation. Clean the mounting surface on the chassis with a wire brush and inspect for corrosion. Verify the compressor intake air filter area is clean and free of debris.
8. 8

   Prepare new compressor
   Unpack the new compressor and verify part number matches the OEM specification for the EDV 500. Install new O-rings on all four air line quick-connect fittings using a light coating of silicone grease. Verify the compressor drain valve is in the closed position. Check that the electrical connector seal is properly seated.
9. 9

   Install new compressor assembly
   Position the new compressor into the mounting location through the wheel well opening. Align the upper mounting bracket holes first and install the three 10mm bolts finger-tight. Support the compressor and install the two lower 13mm mounting bracket bolts finger-tight. Torque all mounting hardware in a cross pattern to manufacturer specifications (not available in database - use OEM service information).
10. 10

    Reconnect air supply lines
    Connect each air line to its corresponding port on the compressor using the labels applied during removal. Push each line firmly into the quick-connect fitting until you hear an audible click. Tug gently on each line to verify secure connection. Ensure no lines are kinked, pinched, or routed near sharp edges.
11. 11

    Reconnect electrical components
    Install the compressor relay and fuse in the auxiliary fuse box. Connect the electrical connector to the compressor, pressing firmly until the locking tab clicks into place. Verify connector is fully seated with no gap between connector body and compressor housing.
12. 12

    Reinstall protective covers and wheel components
    Install the compressor protective cover using the three T30 Torx fasteners. Reinstall the inner fender liner and secure all panel clips. Reinstall the driver-side rear wheel and torque lug nuts to Rivian specification.
13. 13

    Reconnect battery and initialize system
    Lower vehicle from jack stands. Reconnect the 12V auxiliary battery. Connect the Rivian diagnostic scanner and clear any stored fault codes related to air suspension system disconnect. Initialize the new compressor through the 'Air Suspension Component Replacement' function in the diagnostic software.
14. 14

    Perform system calibration and leak test
    Using the diagnostic scanner, command the air suspension system to normal ride height. Monitor compressor operation for normal sound and run time (typically 60-90 seconds for initial pressurization). Check all air line connections for leaks using soapy water solution. Verify system achieves and maintains target pressure with compressor shutting off automatically.
15. 15

    Complete functional testing
    Cycle the air suspension through all ride height settings using the diagnostic scanner or vehicle controls: Entry, Normal, Sport, and Off-Road (if equipped). Verify smooth operation with no abnormal noises. Confirm compressor cycles on and off appropriately to maintain pressure. Test drive vehicle at low speed to verify suspension responds correctly to height adjustment commands.

Reassembly

1. Ensure all air line connections are secure and verified leak-free before finalizing installation
2. Verify protective covers and fender liner are properly reinstalled to prevent water intrusion
3. Double-check that all panel fasteners and wheel lug nuts are torqued to specification
4. Confirm no tools or parts were left in the work area before closing access panels

Verification

• Use diagnostic scanner to verify no active or pending air suspension fault codes
• Confirm compressor operation through at least three full suspension height cycles without fault
• Verify all four corners of vehicle achieve correct ride height within specification
• Check that compressor run time is within normal parameters (typically under 2 minutes for height changes)
• Perform visual inspection of all air line connections for leaks after 24 hours of operation
• Test drive vehicle and verify suspension height adjustments function correctly while driving
• Confirm vehicle maintains ride height overnight without excessive compressor cycling (check after 12-24 hours)
