Technical Description (Comment)

WARNING: This page is about a different variant/trim than selected.

Assuming that another keyless operation key has already been registered with KOS-ECU, if the registration of the keyless operation key ID fails when a new keyless operation key is added or the existing key is replaced, KOS-ECU determines that there is a problem.
