B1364
DTC B1364
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.
These test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.
The SDM inspects the wiring connection to the driver belt pretensioner module by letting the perpetual current flow through the internal circuit and verify the resistance. If the resistance is between 2-10 kilo ohms, the defect may occur depending upon the SDM. The normal resistance is over 10 kilo ohms.
DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B1364 Driver Pretensioner Deployment Loop Short to Battery
CONDITIONS FOR RUNNING THE DTC
Ignition voltage is within the normal operating voltage range.
CONDITIONS FOR SETTING THE DTC
- The belt pretensioner wiring of the driver high is shorted to battery wiring.
- The belt pretensioner wiring of the driver low is shorted to battery wiring.
ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON.
CONDITIONS FOR CLEARING THE DTC
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
