Circuit Description
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.
In case of pretensioner explosion without front air bag inflation due to insufficient impact, replace the exploded belt pretensioner and remove the defect code using the scan tool. If the belt pretensioner explosion counts over 5, then the SDM should also be replaced.
Conditions for Setting the DTC
The history of belt pretensioner explosion is in the SDM.
