Honda Civic central locking and dome light issues possibly related to control box malfunction on Honda Civic

Some Honda Civic owners report experiencing central locking and dome light issues, which may be linked to a malfunctioning control box. These problems can often be resolved by replacing the dome light bulb or checking for a blown fuse. Additionally, some owners encounter central locking failures, such as doors unlocking but not locking, which may stem from issues with the central locking wiring loom plug located behind the driver's door panel. The automatic mode for the dome light, controlled by the MICU in the fuse box, may also contribute to these issues when doors are opened or unlocked via the FOB. Some users have noted that central locking failures can coincide with flat batteries, potentially due to continuous central locking activity draining the battery. Furthermore, it is crucial to ensure that the key used for the vehicle is correct and properly programmed, as an incorrect key can lead to central locking problems. If common solutions do not resolve these issues, inspecting and possibly replacing the control box is advisable.
