Conditions for Running the DTC



Ignition voltage is between 9-16 volts.



Conditions for Setting the DTC



B0012 01 Stage 1 or B0013 01 Stage 2



The steering wheel module high and/or low circuit is shorted to voltage for 120 milliseconds.



B0012 02 Stage 1 or B0013 02 Stage 2



The steering wheel module high and/or low circuit is shorted to ground for 120 milliseconds.



B0012 04 Stage 1 or B0013 04 Stage 2



The steering wheel module high and/or low circuit is open for 120 milliseconds.



B0012 0D Stage 1 or B0013 0D Stage 2



The steering wheel module deployment loop resistance is greater than 5.1 ohms for 120 milliseconds.



B0012 0E Stage 1 or B0013 0E Stage 2



The steering wheel module deployment loop resistance is less than 1.3 ohms for 120 milliseconds.



Action Taken When the DTC Sets



* The SDM request the instrument panel cluster (IPC) to illuminate the AIR BAG indicator ON.



* The SIR system is disabled and no deployments are allowed.



* 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.
