Air Suspension Compressor

This procedure covers the removal and replacement of the air suspension compressor on a 2025 Rivian EDV 500, including electrical disconnection, air line removal, and system reinitialization.

Warnings

Tools required

Parts

• Air suspension compressor assembly × 1 — Use OEM specification
• Air line O-rings × 4 — Use OEM specification
• Compressor mounting hardware × 1 — Use OEM specification if damaged
• Electrical connector seal × 1 — Use OEM specification if damaged

Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks at front and rear of wheels
3. Connect Rivian diagnostic tool and save suspension system fault codes
4. Use diagnostic tool to enter 'Air Suspension Service Mode' to depressurize the system completely
5. Disconnect 12V auxiliary battery and wait 5 minutes for system capacitors to discharge
6. Raise vehicle using approved lift points and support on jack stands
7. Remove rear driver-side wheel for access to compressor compartment
8. Remove rear driver-side wheel well liner fasteners and pull liner forward for access

Procedure

1. 1

   Access compressor compartment
   Remove the protective shield covering the air suspension compressor assembly. Remove the four Torx fasteners securing the shield and carefully remove it, noting the location of any wiring clips attached to the shield.
2. 2

   Disconnect electrical connector
   Locate the main electrical connector on the compressor assembly. Press the locking tab and carefully disconnect the connector. Inspect the connector seal for damage and replace if cracked or worn.
3. 3

   Disconnect compressor relay
   Locate and disconnect the compressor relay connector near the compressor mounting bracket. This is a secondary power feed that must be disconnected to prevent system faults.
4. 4

   Label and disconnect air supply lines
   Using the air line disconnect tool, carefully release and disconnect the four air supply lines from the compressor distribution block. Label each line with its position (LF, RF, LR, RR) for correct reconnection. Inspect O-rings on each fitting and prepare replacements.
5. 5

   Disconnect air dryer line
   Disconnect the air dryer supply line from the top of the compressor assembly. This line connects to the desiccant dryer cartridge. Cap or plug the line to prevent contamination.
6. 6

   Remove compressor mounting bolts
   Remove the three main mounting bolts securing the compressor to the chassis bracket. Support the weight of the compressor assembly as you remove the final bolt, as the unit weighs approximately 15 pounds.
7. 7

   Remove compressor assembly
   Carefully maneuver the compressor assembly out of the mounting location. The unit must be tilted and rotated to clear the wheel well and surrounding components. Take care not to damage any remaining air lines or electrical harnesses.
8. 8

   Inspect mounting location
   Clean the compressor mounting bracket and inspect for corrosion or damage. Check the chassis grounding point and clean if necessary to ensure proper electrical ground for the new compressor.
9. 9

   Prepare new compressor
   Unpack the new compressor assembly and verify part number matches the original unit. Install new O-rings on all air line fittings, lubricating lightly with clean air suspension system lubricant or glycerin.
10. 10

    Install new compressor
    Position the new compressor assembly into the mounting location, ensuring all mounting holes align properly. Thread in the three mounting bolts finger-tight before final tightening. Torque mounting bolts in a cross pattern. Note: Torque specifications not available in database - follow manufacturer service information.
11. 11

    Reconnect air lines
    Reconnect all four suspension air lines to their labeled positions on the distribution block. Push each line firmly until you hear and feel the click of the quick-connect fitting engaging. Gently pull on each line to verify secure connection.
12. 12

    Reconnect air dryer line
    Reconnect the air dryer supply line to the top of the compressor assembly, ensuring the quick-connect fitting is fully seated.
13. 13

    Reconnect electrical connections
    Reconnect the compressor relay connector and the main compressor electrical connector. Ensure both connectors are fully seated and locking tabs are engaged. Verify no moisture is present in connectors.
14. 14

    Reinstall protective components
    Reinstall the compressor protective shield with its four Torx fasteners. Secure any wiring clips to the shield. Reinstall the wheel well liner and all fasteners.

Reassembly

1. Reinstall rear driver-side wheel and torque lug nuts to specification
2. Lower vehicle from jack stands
3. Reconnect 12V auxiliary battery
4. Connect Rivian diagnostic tool and clear 'Air Suspension Service Mode'
5. Allow system to pressurize - this may take 3-5 minutes on initial startup
6. Monitor for air leaks around all connections using soapy water solution

Verification

• Using diagnostic tool, verify compressor communication and no fault codes present
• Perform suspension system leak test using diagnostic tool
• Command each corner of suspension to raise and lower independently to verify proper air distribution
• Verify compressor cycles properly and reaches target pressure within normal time (typically 2-3 minutes)
• Perform ride height calibration procedure using diagnostic tool per manufacturer specifications
• Road test vehicle and verify all suspension modes function correctly (Conserve, All-Purpose, Sport, Off-Road)
• Verify no air leaks audible from compressor area after 24-hour settling period
