What to do if Banks Tuner shows OBDII / BanksBus CAN communication error?
- MMichael MillerJul 28, 2025
If your Banks Tuner displays an OBDII / BanksBus CAN communication error, turn the ignition OFF and inspect the following connections: 1) Check the 61300-35 OBD-II Interface Cable at the 16-pin vehicle OBD-II and 4-pin inter-cable connectors. 2) Check the 61301-21 Y-Adapter Cable at the 4-pin inter-cable and 6-pin inter-cable connectors. 3) Check the 61301-20 B-Bus Starter Cable at the 6-pin inter-cable and 6-pin B-Bus Circular connectors. 4) Check the 61300-22 B-Bus Terminator Plug at the 6-pin B-Bus Circular connector. After checking the connections, turn the ignition back ON and see if the error code reappears. If it doesn't, start the engine and check for the code at engine idle and under various driving conditions.
