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 airbag firing circuit. The SDM allows a very
small amount of current to flow through the circuit. The
SDM monitors the voltage during this check.
DTC 08 Will Set When
D The firing circuit is shorted to the voltage.
DIAGNOSTIC TROUBLE CODE (DTC) 08
Test Description
