Air Bag Resistor: Description and Operation
The resistor module is inserted In the SIR harness between the inflater module and the DERM. The resistor module allows the DERM to monitor
the deployment loop for faults and also allows the DERM to detect when a deployment has occurred.
The resistors in the resistor module are balanced with the resistors in the arming and discriminating sensors. This allows the DERM to monitor
voltage drops across the deployment loop component conditions. Faults are detected during normal non-deployment conditions by monitoring
these voltages.
