Rivian charger shows E006 and refuses to start; app indicates ‘Ground not detected’ or ‘Improper grounding’

Safety first: A missing or poor ground is dangerous. Do not bypass ground detection.

• Step 1 – Visual ground check: Turn OFF the breaker. Remove the charger cover. Confirm the green or bare copper ground conductor is firmly attached to the ground terminal inside the Rivian charger.
• Step 2 – Panel ground: At the main or subpanel, verify the ground conductor from the charger circuit is properly landed on the ground bar and that the bar is bonded as required by code.
• Step 3 – Check mounting hardware: If the charger uses a metal backplate, ensure it is not relying solely on mechanical mounting for ground. The dedicated ground conductor must be present.
• Step 4 – Continuity test (for electricians): With power OFF, measure continuity between the charger ground terminal and the main panel ground bar. High resistance indicates a wiring issue.

If wiring is correct and E006 persists, the internal ground detection circuit on the control board may be faulty and requires board replacement by a qualified technician.
