Tesla Model 3 HVIL Troubleshooting FAQ

The HVIL is part of the vehicle's high-voltage safety monitoring. An interlock fault requires qualified diagnosis of the relevant circuit and connections; it is not a request to bypass a safety feature.
Tell us about recent repairs, impacts or disconnections. That history helps target the inspection, but the alert still needs diagnosis before the cause can be confirmed.
No. Do not open the battery or handle high-voltage connectors. Share the warning with the service team and follow the vehicle's instructions about driving and charging.
Yes. Provide the VIN and production year when arranging hvil troubleshooting. The Model 3 name spans different versions, so the fitted parts and required procedure must be identified before the work is planned.
