  If a check code appears on your Toshiba Air Conditioner's remote controller, it could be due to several reasons: * The outdoor unit power might be off: Ensure the outdoor unit is powered on. * Address setup errors: Redo the address setup, as there may be undefined or mismatched line addresses, or duplicated indoor addresses. * Communication issues: Check the communication connector between the indoor and outdoor units and verify SW30 bit 2 on the outdoor unit.

This is especially important if only line addresses of the connected indoor units are undefined, the outdoor line address and the line addresses of all the indoor units do not match, or the indoor addresses are duplicated.
