Tools required

Preparation

1. Verify the vehicle VIN and current software version using the instrument cluster or infotainment system (Settings > About Vehicle)
2. Check Rivian Service Portal for available software updates and download the update package
3. Ensure the high voltage battery state of charge is at least 60% or connect a battery maintainer
4. Park the vehicle on level ground in a climate-controlled environment
5. Turn off all vehicle accessories including HVAC, infotainment, and lighting
6. Ensure the vehicle has no active fault codes that would prevent the update
7. Verify stable internet connectivity for the duration of the update

Procedure

1. 1

   Access vehicle diagnostic port
   Locate the OBD-II diagnostic port under the driver's side dashboard, typically above the pedal assembly. Connect the Rivian service cable or compatible OBD-II diagnostic tool to the port ensuring a secure connection.
2. 2

   Power up vehicle systems
   Press the brake pedal and press the power button twice without starting the drive motors to place the vehicle in accessory mode. Verify all dashboard lights illuminate and the main display is active.
3. 3

   Connect to Rivian Service Portal
   Open the Rivian Service Portal on your laptop or tablet. Connect the diagnostic tool to your computer via USB. Launch the diagnostic software and establish communication with the vehicle. Verify the VIN displayed matches the vehicle being serviced.
4. 4

   Perform pre-update diagnostic scan
   Run a complete system scan to identify any existing fault codes or module communication errors. Document all fault codes present before the update. Clear any non-critical codes that may interfere with the update process. Address any critical faults before proceeding.
5. 5

   Select software update package
   In the Rivian Service Portal, navigate to the Software Update section. Select the appropriate update package for the EDV 500 Dual Motor AWD configuration. Review the update release notes to understand what systems will be updated and any special procedures required.
6. 6

   Verify update prerequisites
   Confirm the software displays all prerequisites are met: battery charge level is adequate, all modules are communicating, vehicle is in Park, and no critical faults are present. The system will prevent update initiation if any prerequisites fail.
7. 7

   Initiate software update
   Click 'Start Update' in the service portal. The system will begin transferring the update files to the vehicle. Monitor the progress bar and ensure the connection remains stable. Do not interact with vehicle controls during this process.
8. 8

   Monitor update installation
   The vehicle will begin installing updates to individual modules including the battery management system, drive inverters, telematics gateway, and instrument cluster. The infotainment screen will display update progress. Each module may take 5-15 minutes to update and will reboot automatically. Monitor for any error messages.
9. 9

   Complete module programming
   After all modules are updated, the system will perform a synchronization process to ensure all modules are communicating with the new software version. This typically takes 5-10 minutes. The vehicle may cycle power several times during this process.
10. 10

    Perform post-update calibration
    Once the update completes, the service portal will prompt for post-update calibrations. Follow on-screen instructions to calibrate the accelerator pedal position, brake pedal position, and steering angle sensor if required by the update package.
11. 11

    Run post-update diagnostic scan
    Perform a complete system scan to verify all modules updated successfully and are communicating properly. Compare the module software versions displayed to the expected versions from the update package. Address any new fault codes that appear.
12. 12

    Document update completion
    In the Rivian Service Portal, confirm the update was successful. Save the update report showing all module versions, completion time, and any notes. Print or save a copy for vehicle service records. Disconnect the diagnostic tool from the OBD-II port.

Reassembly

1. Ensure the OBD-II port cover is reinstalled if equipped
2. Return all vehicle settings to customer preferences if they were reset during the update

Verification

• Power cycle the vehicle completely by pressing the power button to shut down, waiting 30 seconds, then powering back on
• Verify the new software version is displayed in Settings > About Vehicle on the infotainment screen
• Test all major vehicle functions: drive motor engagement, regenerative braking, HVAC operation, and infotainment responsiveness
• Perform a short test drive to verify proper acceleration, braking, steering response, and absence of warning lights
• Check for any new fault codes after test drive using the diagnostic tool
• Verify telematics connectivity by confirming the vehicle communicates with Rivian's servers (if equipped with fleet management)
• Confirm all driver assistance features function properly including adaptive cruise control, lane keeping, and blind spot monitoring if equipped
