Hello, I'm working on a 2024 Mazda CX-5 VA40-57k30 - KJ024. The second number on the module is VA40-57k31-0-285-015-694.

I do have a problem with the module communicating to the ocupancy detection system.

The passenger buckle is always buckled, and I'm unable to calibrate the weight sensor.

DTC: B00A0:8F-8B Occupant Classification System - Current.

Other DTCs stay in history

My concern is that the Occupancy Detection configuration appears to have been cleared from the module as well.

Other than that, the module seems to be working correctly.

I already changed the buckle.

Could you please let me know if you have any similar concerns/situations, or how to fix this problem?

[AST_Support]

B00A0 is not a buckle, it is a passenger classification system (weight sensor). If you can't calibrate it, then there must be a problem with it.

[techautoltd]

Okay, I know B00A0 is not a buckle. I will look into it more in-depth. But part of the reason I can't calibrate it is that the passenger buckle is showing constantly buckled, and it's supposed to be unbuckled during calibration of the weight sensor.

I will confirm it, but I believe the Buckle signal is communicated to the SRS module by the seat module, which calculates the weight from the weight sensors.

So if the SRS module faults on ocupancy detection, and there is no reason for the Ocupancy detection to be faulty, as the vehicle only has a couple of thousand kilometres on it that's why I was thinking something is wrong with the SRS module.
