- If there is any malfunction, inspect the parts under "Inspection item (s)".

- If the parts under "Inspection item (s)" are found to be normal (except for terminal 1T), replace the climate control unit.
- For terminal 1T, first try replacing the power MOS FET. If there is still any malfunction, replace the climate control unit.
