Air Suspension Valve Block

This procedure covers the removal and replacement of the air suspension valve block on a 2022 Rivian EDV 500, including depressurizing the system and verifying proper operation.

Warnings

Tools required

Parts

• Air suspension valve block assembly × 1 — Use OEM specification
• Air line O-rings and seals kit × 1 — Rivian air suspension seal kit
• Valve block mounting hardware × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal and wait 5 minutes for system capacitors to discharge
3. Use Rivian diagnostic software to place air suspension in 'Service Mode' and depressurize system completely
4. Raise vehicle on lift to working height ensuring all four wheels are off ground
5. Verify air suspension system shows zero pressure on diagnostic interface
6. Remove belly pan fasteners and lower underbody protective panels to access valve block location
7. Photograph air line connections and electrical connector orientation for reference during reassembly

Procedure

1. 1

   Locate and access valve block
   The air suspension valve block is mounted on the driver side frame rail near the front axle. Remove any remaining shields or brackets that may obstruct access. Clean the area around the valve block and air line connections with compressed air to prevent contamination during disassembly.
2. 2

   Disconnect electrical connector
   Locate the main electrical connector on the valve block. Press the release tab and carefully disconnect the connector. Inspect connector pins for corrosion or damage. If corrosion is present, clean with electrical contact cleaner and allow to dry completely.
3. 3

   Label and disconnect air supply line
   Identify the main air supply line from the compressor (typically the largest diameter line). Use tape or tags to label this line. Press the release collar on the push-to-connect fitting and pull the air line straight out. Some residual air may escape. Cap or plug the line end to prevent contamination.
4. 4

   Disconnect air lines to suspension struts
   Disconnect the four air lines running to each corner suspension strut. Each line should be labeled (LF, RF, LR, RR) either by factory markings or your own tags. Press the release collar on each push-to-connect fitting and remove lines straight out. Place a drain pan underneath as some moisture condensation may drain out. Cap all open ports on valve block and line ends.
5. 5

   Disconnect reservoir air line
   Locate and disconnect the air line running to the air reservoir tank. This line is typically intermediate diameter between supply and strut lines. Press release collar and remove line. Cap the reservoir line end to prevent contamination of the tank.
6. 6

   Remove valve block mounting hardware
   Remove the mounting bolts securing the valve block to the frame rail bracket. Typically there are 3-4 bolts using 10mm or 13mm heads. Support the valve block by hand while removing the final bolt to prevent it from falling. Carefully remove the valve block from the vehicle.
7. 7

   Inspect mounting location and bracket
   With valve block removed, inspect the mounting bracket for damage, cracks, or corrosion. Clean the mounting surface thoroughly. Check frame rail mounting area for any signs of damage from moisture or road debris. Address any corrosion with appropriate rust treatment before installing new valve block.
8. 8

   Prepare new valve block
   Unpack the new valve block assembly. Verify all ports are capped and clean. Check that replacement part number matches original. Inspect all push-to-connect fittings for damage. Apply a small amount of clean air suspension system lubricant (if provided in seal kit) to O-rings on fittings.
9. 9

   Install new valve block
   Position the new valve block onto the mounting bracket, aligning all mounting holes. Install mounting bolts hand-tight first to ensure proper alignment. Once all bolts are started, tighten bolts in a cross-pattern to ensure even pressure. Since no torque specification is provided, tighten firmly but do not over-torque. Bolts should be snug against the mounting bracket without deforming the valve block housing.
10. 10

    Reconnect air lines
    Beginning with the main air supply line from compressor, insert each air line into its corresponding valve block port. Push firmly until you hear/feel a click indicating the line is fully seated. Gently pull on each line to verify it is locked in place. Connect all lines in this order: supply line, reservoir line, then four corner strut lines (verify correct position using your labels and reference photos).
11. 11

    Reconnect electrical connector
    Align the electrical connector with the valve block connector port, ensuring proper orientation. Push connector firmly until the locking tab clicks into place. Verify connector is fully seated and locking tab is engaged by gently pulling on the connector housing.
12. 12

    Reinstall underbody panels
    Clean and inspect all belly pan and shield mounting points. Reinstall protective panels and shields in reverse order of removal. Ensure all fasteners are properly seated and tightened. Verify no air lines or wiring are pinched by panels.

Reassembly

1. Double-check all air line connections are fully seated and locked
2. Verify electrical connector is properly engaged with locking tab secured
3. Ensure no tools or parts have been left in the work area
4. Confirm all underbody panels are securely fastened

Verification

• Reconnect 12V battery negative terminal
• Connect Rivian diagnostic software and clear any stored fault codes related to air suspension
• Using diagnostic software, command air suspension to pressurize system and monitor for pressure buildup
• Listen carefully for any air leaks at valve block connections during pressurization
• Use soapy water solution on all fittings to check for leaks (bubbles indicate leak)
• Command each suspension corner to raise and lower individually using diagnostic software to verify valve block solenoid operation
• Perform full system calibration procedure using Rivian diagnostic software
• Lower vehicle to ground and cycle through all suspension height settings (Low, Normal, High) to verify proper operation
• Take a test drive and verify suspension responds properly to ride height commands and road conditions
• Check diagnostic software for any new fault codes after test drive
• Verify ride height sensors are reading correctly and vehicle maintains commanded height
