Hi all,
I’m trying to understand whether the Civic XI / FL5 still supports any kind of hidden BCM configuration via physical button sequences, like older Hondas did.
My EU-spec FL5 does not have automatic door locking while driving (the option does not exist in the car settings. Neither the non-adaptative cruise control), and this seems to be region-dependent rather than a hardware limitation. It’s a feature I personally value a lot, especially coming from other cars that had it.
What also bothers me is that when I manually lock the car and then open the driver’s door, the other doors remain locked. It feels unintuitive to me.
I’ve seen aftermarket CAN modules (AliExpress) that enable auto-lock and some other related functions, but I’m hesitant to install anything that interferes with the CAN bus unless there’s no cleaner alternative. There are mixed reports: one user claims it enabled features not present in the car, while another reports battery drain and odd behavior, so it doesn’t sound very promising.
That’s why I’m wondering: on older Civics (pre-2010 and even later), there were undocumented button sequences using the door lock / window switches to change BCM settings. Since the physical button layout hasn’t changed much, I’m curious whether anyone has tested or confirmed if any of those legacy sequences still work on Civic XI / FL5 — even if they’re disabled or region-locked.
I’m not looking for aftermarket solutions here, just trying to understand what’s still supported internally and what’s truly gone.
Has anyone investigated this on FL5 (any market), or can confirm whether button-based configuration is completely dead on EU-spec cars?
Thank you.
Best regards.
