Title: MY SETTINGS: MY SETTINGS SYSTEM: My Setting cannot be Recalled; 2023 - 2025 MY Corolla Corolla Hatchback Corolla HV GR Corolla [09/2022 -        ]

My Setting cannot be Recalled

DESCRIPTION

It may be possible to determine the cause of the problem by the customize setting items which are not recalled or type of registered device for which a recall is not performed. If all customize setting items are not recalled, it is suspected that the main body ECU (multiplex network body ECU) is malfunctioning or there is a My Settings error. If some customize setting items are not recalled, it is suspected that another system is malfunctioning.

CAUTION / NOTICE / HINT

NOTICE:

Before replacing the main body ECU (multiplex network body ECU), refer to Registration.
