DIAGNOSTIC TROUBLE CODE (DTC) 08
PASSENGER FIRING CIRCUIT, SHORT TO BATTERY VOLTAGE
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.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies the reserve
power to deploy the airbags, even if the battery is
disconnected. Unintentional deployment of the air-
bags can cause injury.
