The controller disconnects under acceleration
Identify the electrical reset without rewriting serial reconnect logic.
Pairs with Linux devices and electrical evidence in Hardware Integration & CANopen. Read the concept first, then diagnose it here.

How this lab works
You diagnose it — no command list.
Open the repair workspace and gather your own evidence in a real terminal. No diagnostic commands are handed to you — finding the fault is the exercise. Stuck? Progressive hints unlock inside the workspace.
Verification
Your repair must pass more than the visible symptom.
- No reset at peak acceleration
- Reconnect logic still passes
- Hidden regression behavior
- Root cause explanation
