When the ignition switch is turned to ON, the sensing and diagnostic module (SDM) will perform a turn-on test to diagnose critical malfunctions within the SDM itself.
If the SDM has been used 5 times for 5 explosions of belt pretensioners or side impact modules, the SDM should also be replaced.
This diagnostic procedure supports the following DTC:
DTC 038
Ignition voltage is within the normal operating voltage range.
The count of the belt pretensioner and side impact module explosion is over 5 in the SDM.
The SDM commands the AIR BAG indicator ON.
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
