Tools required

Parts

• Air suspension compressor assembly × 1 — Use OEM specification
• Compressor mounting hardware kit × 1 — Use OEM specification
• Pneumatic line O-rings × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Connect Rivian diagnostic scanner and access air suspension module
3. Enter service mode to depressurize air suspension system completely
4. Disconnect 12V battery negative terminal and wait 5 minutes
5. Verify HV system is in safe state (contactors open)
6. Raise rear of vehicle and support on jack stands at manufacturer-specified lift points
7. Allow air suspension system to fully depressurize for at least 10 minutes
8. Remove rear cargo area driver-side trim panels to access compressor location

Procedure

1. 1

   Access compressor compartment
   Remove the driver-side rear cargo area trim panel by releasing plastic clips using trim removal tools. Remove lower access panel fasteners and carefully pull panel away from body to expose air suspension compressor assembly mounted to chassis frame.
2. 2

   Disconnect electrical connector
   Locate the main electrical connector on the compressor assembly. Press the locking tab and pull connector straight out from compressor. If equipped with secondary ground wire, remove ground bolt and set aside.
3. 3

   Disconnect air supply line
   Identify the main air supply line (typically orange or blue) connecting to compressor outlet. Using plastic line disconnect tool, press release collar and pull line straight out from compressor fitting. Cap or plug line to prevent contamination entry.
4. 4

   Disconnect distribution lines
   Disconnect the four pneumatic distribution lines leading to each wheel air spring. Label each line with position (LF, RF, LR, RR) for proper reconnection. Use line disconnect tool on each quick-connect fitting. Inspect O-rings and replace if damaged.
5. 5

   Disconnect intake filter line
   Locate compressor air intake line with filter assembly. Disconnect intake line from compressor inlet port using appropriate disconnect tool. Note orientation of filter assembly for reinstallation.
6. 6

   Remove compressor bracket bolts
   Remove the mounting bolts securing compressor bracket to chassis frame. Typical configuration uses four bolts in square pattern. Support compressor weight while removing final bolt to prevent dropping assembly.
7. 7

   Remove compressor assembly
   Carefully maneuver compressor assembly out of mounting location, taking care not to damage remaining pneumatic lines or electrical wiring. Guide assembly past any obstructions in cargo area. Place removed compressor on clean work surface.
8. 8

   Inspect mounting area
   Inspect compressor mounting bracket and chassis mounting points for damage, corrosion, or cracks. Clean mounting surface with shop towels. Check that all pneumatic line routing clips and holders are intact.
9. 9

   Install new compressor assembly
   Position new compressor assembly in mounting location, aligning mounting holes with chassis frame. Ensure compressor is properly oriented with inlet/outlet ports accessible. Install mounting bolts hand-tight initially.
10. 10

    Torque mounting bolts
    Torque compressor mounting bolts in cross-pattern sequence to ensure even clamping. Follow manufacturer torque specifications when available. Verify compressor assembly is secure with no movement.
11. 11

    Connect pneumatic lines
    Connect all pneumatic lines to new compressor in correct positions using labels from removal. Push each line firmly into quick-connect fitting until audible click is heard. Tug gently on each line to verify secure connection. Install new O-rings if provided with replacement compressor.
12. 12

    Connect electrical connector
    Plug main electrical connector into new compressor until locking tab clicks into place. If equipped with separate ground wire, reconnect and torque ground bolt to specification. Ensure no wires are pinched or under tension.
13. 13

    Perform system initialization
    Reconnect 12V battery negative terminal. Using Rivian diagnostic scanner, access air suspension module and run compressor initialization procedure. This will prime new compressor and verify electrical operation before pressurizing system.

Reassembly

1. Reinstall all cargo area trim panels and secure all fasteners
2. Remove jack stands and lower vehicle to ground
3. Ensure all tools and parts are removed from vehicle
4. Verify all pneumatic connections are secure with no air leaks audible

Verification

• Using diagnostic scanner, command air suspension system to normal ride height and verify all corners raise properly
• Perform leak test by listening for air escaping at all compressor connections while system pressurizes
• Cycle suspension through all ride height settings (low, normal, high) and verify proper operation
• Check for fault codes in air suspension module and clear any soft codes related to compressor replacement
• Verify compressor duty cycle and pressure build times are within normal parameters using scanner data
• Test drive vehicle and verify ride quality is normal with no suspension warning lights illuminated
• Perform final visual inspection of compressor area for any loose connections or abnormal conditions
