Seatbelt chime is ruining my life

[PaskL]

2005 GT, seatbelt light and chime live a life of their own outside of reality

When starting it up the seatbelt light is illuminated for ~60 seconds regardless of the actual status of the belts. Then it will start flashing and chiming for about 5 sec every 30 seconds if I start driving. Both the chime and light coming and going every 30 sec. With the scan tool and looking at live data, everything checks out - buckling and unbuckling status changes correctly for both belts, passenger occupancy sensor works. When the chime starts, the scan tool still displays belt status as buckled. I tried the chime disabling method and it seems to "work" as the chime status in the scan tool changes to "unactive". But still no effect on the issue at hand. No fault codes

Something has triggered this weird routine in the system and it seems to be ignoring the restraint control module and sensors which seem to be functioning properly and sending the correct data...

Hope someone can help this loser out

How long has this been going on and has there been [any] maintenance done on the car prior to it starting?

How [wet] is it where you live?

I bought it from the US with this fault and had it shipped overseas. When it arrived in the middle of winter the shipping company had left the window down and there was loads of snow in the car. I already replaced the belt locking mechanism for another used one before I did any further digging which didn't help.

You didn't think this was relevant to the initial post?


Look into this part: 2005 Mustang GT BCM/SJB 5R3Z-15604-AA
Have you checked for codes?


Other possibilities would include water still sitting someplace it should not and/or corroded wires or contacts resulting from previous water contact. This means you're going to need a wire diagram:

Something like this: https://www.ebay.com/itm/1527824643...GNvYObS5qMJFtTxdVSIR9ZakqU0=|tkp:BFBM9rTmytNl


BTW, I should also mention that the "chime" is located inside of that SJB I listed above.

No other electrical issues at all so kind of forgot about it , no codes in any of the modules. Interior was completely stripped and cleaned out. I'll look further into the BCM, thanks.

Can't help with your issue, but one of my all time favorite places i've travelled to was Tallinn, Estonia.
