The inflatable restraint module deployment loop resistance is greater than 3.9 ohm for 120 milliseconds.
B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E
The inflatable restraint module deployment loop resistance is less than 1.1 ohm for 120 milliseconds.
Action Taken When the DTC Sets
* The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator ON.
* The SDM will store a DTC, however if an event occurs the system will still attempt deployments.
Conditions for Clearing the DTC
* The condition for setting the DTC no longer exists.
* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.

Circuit/System Testing
Note:
* Refer to SIR Service Precautions (See: Restraints and Safety Systems/Air Bag Systems/Service Precautions/Technician Safety Information).
* When removing connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the
affected component/connector:
- The pretensioner
- The inflatable restraint module
- The SDM
- The inflatable restraint module wiring harness connector
- The SDM wiring harness connector
Note: The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat
with an audible and/or tactile click. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate
properly.
1. Verify that the appropriate inflator restraint module connector and the CPA are engaged.
