Interestingly, I did not detect a current. I tried with the car, engine running, in D and P without handbrake.
The only way to test it fully would be to drive around with the multimeter connected to see if the current "spikes" when the seatbelt warning chime sounds (I don't have time to do this at the moment).
If it did, and the computer is only sending the current when it needs to check if the seatbelt is engaged, then we have a good signal to trip the autolock

Your pictures are very useful and most proper for this thread. It is clear that there are extra sockets in that connector, maybe for the heated seats or motorized recliner?

My own way of testing would be to use a crocodile clip attached to the body ground connected to the negative lead of the multimeter, one of the wires in question attached to the positive lead and hunt for voltage not amperage (current). Computer logic signals draw negligible amperes from sensors so even those rubber switches on your Playstation controllers work to transmit the signal of being depressed.

It is very possible to rig the brake pedal switch in series with the seatbelt switch so that when you pull out of your garage while your wife is still outside the car, the lock is not yet "armed". Once you insert the seatbelt tab, auto lock via pedal is enabled.

I should be able to investigate the seatbelt sensor by this weekend and report my observations.

I wont be doing this mod however on my own ride since the pedal only mod does the trick perfectly. Even while the engine is off in a dark parking lot, the locks engage upon pedal press. This won't happen if the requirement was to be running a certain speed for them to engage.

My Honda auto-locks upon pedal press only when the engine is running and all doors are shut well.

Guys, I just tried this, and sure enough, seatbelt icon flashed 3 times in the dash.....so I assume it worked. I will try it later to see if the chime is really disabled. It seems like our car is very similar to the UK version when it comes to software.

^^ sir kevo888, please confirm as well if this can be reverted back to its original settings after disabling it. thanks mate!

The chime disabling works. I imagine a "battery disconnect" would enable it again, not tested yet.

^^ thanks for the confirmation on the disabling part.

would you mind repeating the same procedure to check if this will enable the chime back? i just found this thread which works for the mondeo and 1 procedure is done on activating/deactivating the seatbelt minder:

the reason for me asking is because i dont wanna disable my seatbelt minder permanently. hehehe. thanks again sir kevo888!

Tested and confirmed.....
Repeating procedure re-enables chime.
No need for "battery reset".

**pista_ni_jon** · March 1st, 2011 05:30 PM

^^^ alright! thanks sir kevo888!

mabuhay ka!

omg thanks for this. nakakairita ung chime e. lalo na kung you have to drive within the village lang nakakatamad na mag seatbelt! i dont need the chime naman na kasi habit ko na mag seat belt pero there are moments talaga na ayaw ko magseatbelt. will try this later. :D

One of the first things i bought for my car was this seatbelt lock extention from Blaze festival mall, its sort of a middleman between the seatbelt, and the lock, but is also a lock in itself.

Since its attached to the lock, the car reads it that you have a seat belt on and stops the chime, for a sari sari store trip, so i leave it there.

The good thing about this, is when you do need to put your seatbelt on, you simply attach your seatbelt to it. I stressed test it, and it is as sturdy as having your seatbelt locked directly.

Very handy indeed, and very cheap too, plus no wires to cut.
