This procedure covers the removal and replacement of the fog light bulb assembly on the 2023 Rivian EDV 500 electric delivery van.

Warnings

⚠The Rivian EDV 500 uses integrated LED fog light modules, not traditional bulbs. Replacement requires the complete LED assembly module.

⚠Disconnect the 12V battery before working on lighting circuits to prevent short circuits and module damage.

ℹ️This vehicle has a 12V auxiliary battery in addition to the high-voltage traction battery. Only the 12V battery needs to be disconnected for this procedure.

Preparation

Park vehicle on level surface and apply parking brake
Turn off vehicle and remove key fob from cabin
Allow vehicle to fully power down (wait 2 minutes after shutdown)
Open front cargo area or hood to access 12V auxiliary battery compartment
Disconnect negative terminal on 12V auxiliary battery and secure cable away from terminal
Determine which fog light requires replacement (driver or passenger side)

Procedure

1
Access front bumper lower section
If working on the driver side, turn the steering wheel fully to the right. If working on passenger side, turn steering wheel fully to the left. This provides better access to the wheel well liner and fog light area.
2
Remove wheel well liner fasteners
Locate the front section of the wheel well liner directly behind the fog light location. Remove the three T25 Torx screws securing the forward portion of the liner. Pull the liner away gently to expose the back of the fog light housing.
3
Disconnect fog light electrical connector
Locate the electrical connector on the rear of the fog light assembly. Press the locking tab on the connector and pull straight back to disconnect. Do not pull on the wiring harness itself.
4
Remove fog light mounting fasteners
Using a 10mm socket with extension, remove the two mounting bolts securing the fog light assembly to the bumper bracket. Support the fog light assembly with one hand while removing the second bolt to prevent it from falling.
5
Remove fog light assembly from bumper
Carefully pull the fog light assembly forward and out through the bumper opening. Note the orientation and position of any alignment tabs or gaskets. If resistance is felt, check for additional clips or fasteners that may have been missed.
6
Transfer mounting hardware if necessary
Inspect the mounting brackets and rubber isolation grommets on the old assembly. If the new LED module does not include these components, carefully transfer them from the old assembly to the new one. Ensure all rubber seals and gaskets are in good condition.
7
Install new fog light LED module
Position the new fog light assembly into the bumper opening, aligning the mounting tabs with the bracket holes. Ensure the gasket seal is properly seated around the perimeter to prevent water intrusion.
8
Secure fog light mounting bolts
Install the two 10mm mounting bolts finger-tight first to ensure proper alignment. Then tighten the bolts evenly in a cross pattern until snug. Do not overtighten as this can crack the housing or compress the mounting grommets excessively.
9
Reconnect electrical connector
Connect the electrical connector to the new fog light assembly, pushing firmly until the locking tab clicks into place. Gently tug on the connector to verify it is fully seated and locked.
10
Reinstall wheel well liner
Position the wheel well liner back into place and reinstall the three T25 Torx screws. Ensure the liner sits flush and does not interfere with any wiring or the fog light assembly.
11
Reconnect 12V battery
Return to the 12V auxiliary battery compartment and reconnect the negative terminal. Tighten the terminal clamp securely.
12
Initialize vehicle systems
Enter the vehicle with the key fob and power on the vehicle. The system may take 30-60 seconds to fully initialize after battery reconnection. Allow all vehicle systems to complete their startup sequence.

Reassembly

Return steering wheel to center position after testing
Close all access panels and cargo areas
Verify wheel well liner is properly secured and not rubbing on tire

Verification

Turn on the fog lights using the vehicle lighting controls to verify the new LED module illuminates properly
Check for proper beam pattern and alignment by observing light output on a wall or garage door from approximately 25 feet away
Verify no warning lights or error messages appear on the instrument cluster related to exterior lighting
Inspect the fog light area for proper sealing and ensure no gaps exist around the housing that could allow water intrusion
Test fog lights in both on and off positions multiple times to ensure reliable operation
