What the manual describes
CC_a001 is summarized in this research set as: Wall Connector grounding problem.
The linked Tesla troubleshooting-alert page gives the full heading and context. This short description is for the 2020–2024 Model Y manual; do not transfer it to a newer Model Y, another Tesla, or a different software build without checking that vehicle’s current manual.
How this alert differs
This is a Wall Connector grounding issue. It points to charging equipment and electrical supply, not proof of a failed traction battery; stop using the affected equipment and involve a qualified electrician.
Response in this manual context
Stop using the affected charging equipment; use qualified electrical service, not a vehicle-parts guess.
Follow the precise instruction displayed in the vehicle. If the vehicle says it cannot drive or restart, or if braking, steering, propulsion, smoke, smell or charging equipment is unsafe, move to safety and seek the appropriate Tesla, roadside or electrical professional help. Do not open high-voltage hardware.
Record before contacting service
- The full alert ID, headline and body text, photographed only while safely parked.
- Model year, current software version and any other active alerts.
- Whether the condition changed charging, power, braking, steering or restart behavior.
- When the alert occurred and whether it persists on later trips.
What this alert does not prove
An alert may describe an unavailable function or a system condition without identifying a replaceable component. A later manual or software version may revise its action. Check Tesla’s current original text for this exact vehicle, and ask service to verify the cause and any applicable coverage before authorizing work.
