BMS CANBus Loopback
From Unofficial Zero Manual
The cabling ends in a multi-pin connector and should either:
- Terminate with a Loopback Blanking Plug that wires two pins together in a loopback circuit.
- Connect to a Power Tank's corresponding communications cable.
If one of the above conditions do not hold, the MBB is configured to issue error code 35.
- It is unconfirmed what purpose the loopback mechanism serves.
- Hypothesis: This is a hardware debugging mechanism for a loose connector.
