B1350 — よくあるご質問
Can a slightly high resistance really matter? +
Yes. Deployment energy is calculated for the specified loop resistance; extra resistance can mean no deployment.
Can I solder the repair? +
Follow the manufacturer's guidance — many require crimped splices and prohibit solder in restraint circuits.
