✓Expert-verified. Personally reviewed and approved by OLP's master technicians (Chris Hackleman — 20+ years each). Always follow the vehicle's factory service information and torque specs.

This procedure safely disconnects the high-voltage battery system on the 2023 Rivian EDV 500, isolating all electrical power for service work requiring complete system shutdown.

Warnings

⚠️High-voltage system operates at up to 800 volts DC. Contact can cause severe injury or death. Only qualified technicians with HV certification should perform this procedure.
⚠️Wait minimum 15 minutes after disconnecting HV service disconnect before touching any orange high-voltage cables or components to allow capacitor discharge.
⚠️Always verify zero voltage with a properly rated multimeter before proceeding with any HV component work.
⚠Do not wear jewelry, watches, or conductive accessories when working with high-voltage systems.
⚠Ensure vehicle cannot roll or move during service. This procedure requires accessing components under the vehicle.
ℹ️Battery disconnect service disables all vehicle functions including keyless entry. Ensure alternative access method is available.

Preparation

  1. Verify technician has completed manufacturer-approved high-voltage safety training and is wearing appropriate personal protective equipment
  2. Park vehicle on level surface and apply parking brake firmly
  3. Place wheel chocks at all four wheels
  4. Ensure ignition is OFF and key fob is at least 15 feet away from vehicle
  5. Open driver and passenger doors to prevent lockout
  6. Document any active diagnostic trouble codes before beginning procedure
  7. Verify ambient temperature is within service range (50-90°F recommended for HV work)
  8. Prepare insulated tools and safety equipment within easy reach
  9. Notify all personnel in work area that high-voltage service is being performed

Procedure

  1. 1
    Disable vehicle systems and verify power-down
    Ensure vehicle is completely powered down. Press brake pedal and start button to verify vehicle will not power on. Confirm instrument cluster remains dark and no charging activity is occurring. Disconnect 12V auxiliary battery negative terminal using 10mm socket and isolate cable end away from battery post.
  2. 2
    Access HV service disconnect location
    Raise vehicle using floor jack at manufacturer-specified lift points. Secure with jack stands rated for vehicle weight. Remove rear belly pan access cover using T30 Torx bit to expose high-voltage battery compartment service disconnect area. The service disconnect is located on the driver side of the battery pack enclosure.
  3. 3
    Remove HV service disconnect cover
    Put on Class 0 electrical safety gloves. Remove HV service disconnect protective cover by releasing four T40 Torx fasteners. Inspect cover seal for damage and set aside for replacement. Visually inspect area for any signs of damage, corrosion, or coolant leaks before proceeding.
  4. 4
    Verify HV system status indicators
    Check HV status indicator light on service disconnect housing. If LED is illuminated, system still has active voltage. Verify vehicle has been off for at least 2 minutes to allow contactors to open. Orange LED should be extinguished before proceeding to disconnect.
  5. 5
    Remove HV service disconnect
    While wearing insulated gloves, grasp HV service disconnect handle firmly. Rotate counterclockwise 90 degrees until unlock position is felt. Pull disconnect straight out from housing with steady pressure. Do not twist or bend during removal. Place disconnect on insulated surface away from work area.
  6. 6
    Install service disconnect lock and tag
    Insert service disconnect lock device into empty disconnect receptacle to prevent accidental reconnection. Attach service disconnect lock tag indicating service in progress, technician name, and date. Store removed service disconnect in secure location with restricted access.
  7. 7
    Wait for capacitor discharge period
    Wait minimum 15 minutes to allow high-voltage bus capacitors to discharge below safe voltage levels. Do not touch any orange high-voltage cables or components during this waiting period. Use timer to ensure full discharge time is observed.
  8. 8
    Verify zero voltage on HV bus
    Using 1000V CAT III rated digital multimeter with insulated test leads, verify voltage between HV positive and negative bus bars at service disconnect location. Reading must be less than 5V DC. Test between each HV terminal and vehicle chassis ground. Document voltage readings. If voltage exceeds 5V, wait additional 5 minutes and retest.
  9. 9
    Inspect HV connectors and cables
    With zero voltage confirmed, visually inspect all visible orange HV cables for damage, discoloration, or contamination. Use UV flashlight to check for corona discharge evidence around HV connectors. Inspect service disconnect pins for damage, corrosion, or burning. Document any abnormalities found.
  10. 10
    Verify isolation from vehicle systems
    Confirm that HV battery is fully isolated from all vehicle systems. Test for voltage at inverter HV terminals and motor controller inputs using multimeter. All readings should be zero volts. Verify drive unit contactors are open and showing no continuity.
  11. 11
    Document battery disconnect completion
    Record completion of battery disconnect procedure including: date, time, technician name, voltage verification readings, condition of HV components inspected, and reason for disconnect. Photograph service disconnect lock installation and tag placement for service records.

Reassembly

  1. Before reconnection, verify all service work is complete and all tools are removed from vehicle
  2. Inspect HV service disconnect pins and receptacle for any contamination or damage
  3. Remove service disconnect lock device and store for future use
  4. Align service disconnect with receptacle and insert straight in until fully seated
  5. Rotate service disconnect handle clockwise 90 degrees to locked position
  6. Install new HV service disconnect cover seal on protective cover
  7. Reinstall HV service disconnect protective cover with T40 Torx fasteners in cross pattern
  8. Reinstall rear belly pan access cover with T30 Torx fasteners
  9. Lower vehicle from jack stands and remove chocks
  10. Reconnect 12V auxiliary battery negative terminal and torque to specification
  11. Verify HV status indicator LED illuminates when vehicle is powered on
  12. Clear any stored diagnostic trouble codes related to HV disconnect if applicable

Verification

  • Power on vehicle and verify instrument cluster displays normally without HV system fault warnings
  • Confirm READY status can be achieved and drivetrain responds to accelerator input
  • Verify HV battery status shows normal voltage (approximately 650-800V depending on state of charge)
  • Check for any new diagnostic trouble codes related to HV system
  • Test charge port functionality if vehicle was disconnected for charging system service
  • Confirm all vehicle functions operate normally including climate control, power steering, and regenerative braking
  • Perform short test drive to verify motor operation and battery management system functionality
  • Document reconnection completion and final system status in service records
