Cant understand whats wrong. Please hrlp me with it
B00051B - Collapsible Steering Column Deployment Control

More or less above the brake pedal is an electrical connector on the steering column for an explosive charge anchor for steering column. It determines whether the steering column collapse in a severe frontal accident is at higher force if the driver is unbelted since the steering wheel airbag needs to be more supportive or it blows to let steering column collapse at lesser force if driver is belted as the belt will handle the restraint.
That circuit has high resistance. It could be unplugged or the end connector has a capacitor circuit in it and the cap could be bad. The harness end connector is replaced for that problem.

Can the connection to the steering wheel collapse sensor be hot-wired to appear as if the sensor had not been triggered, and clear the fault code?
After City Safety failed to brake to avoid what should have been a preventable minor front end collision, a simple swap of driver airbag now also necessitates removal of the steering column due to the triggered sensor. (Of course, Volvo won’t even sell me the module, but rather the entire, costly steering column). I found a source for a cannibalized collapse sensors which i can presumably swap out to the existing steering column, but i would just as soon disable the collapse feature entirely and clear the fault code. Either that, or learn to drive without a seatbelt to lessen the repair expenses incurred in future collisions when the City Safety system fails affair. I’m guessing a 25 cent resistor with the right value might just be the ticket.

Seems like a terrible idea to try and defeat a safety feature. Kinda the reason to own one of these cars. Also if something were to happen and insurance found that a safety feature was modified, it could result in denied claims.

When you think about it, the design is such that SRS restoration is less costly if you avoid using the seat belt. Why would you design it to be MORE costly for those who drive safely, and less costly for those who are reckless (no seatbelt)? Penalizing and rewarding the wrong behaviors. Should have been designed to increase the cost of SRS restoration for those who failed to belt up.

Or just sell the sensor separately and locate it on the underside of the column, accessible without removal of the column.
