B1361

DTC B1361

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 deployment 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.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B1361 Driver Pretensioner Deployment Resistance High

Conditions for Running the DTC

Ignition voltage is within the normal operating voltage range.

Conditions for Setting the DTC

The resistance of the driver belt pretensioner deploy loop is over 3 ohms.

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.
