The air bag or seat belt retractor pretensioner 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.

* 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 fault-free ignition cycles have occurred.

Diagnostic Aids

* When a harness connector is disconnected, the high control and low control circuits are shorted together by the integral shorting bar. This

should be taken into account when testing for faults on these circuits.

* This DTC usually indicates a poor connection or a wiring malfunction between the SDM and the deployment loop.
