Circuit Description

When the ignition switch is turned ON, the sensing and diagnostic module (SDM) will perform tests to diagnose any malfunctions within itself.

After passing these tests, the SDM will check the passenger pretensioner circuit. The SDM allows a very small amount of current to flow through the circuit. The SDM monitors the circuit resistance during this check.

Conditions for Setting the DTC

The combined resistance of the passenger pretensioner module, the harness wiring, and the connector contacts is below a specified value, as in a short circuit between the wires to the passenger air bag module.
