CAN fails only at full cable length
Restore signal integrity without reducing bitrate as a workaround.
Pairs with Serial and CAN fundamentals 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.
- Resistance near 60 ohm
- Zero error frames at full length
- Hidden regression behavior
- Root cause explanation
