Additional note: If there are any Diagnostic Trouble Codes (DTCs) present in the vehicle that need to be cleared, you can select [Check Module DTCs (Diagnostic Trouble Codes)] from the main menu and follow the steps below.

Turn on the ignition switch and wait for the module self-test to complete. (In this test, the vehicle has no fault codes, so the message "There Is No DTC" is displayed.)

The DTCs related to seat learning are B1231–54 and B1232–54. These are not present in the vehicle used for this test; therefore, third-row seat learning is not required. If a vehicle does have fault codes, they can be cleared via this menu.
