DIAGNOSTIC TROUBLE CODE (DTC) 04
DRIVER 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 driver
airbag module firing circuit. The SDM allows a very
small amount of current to flow through the circuit. The
SDM monitors voltage during this check.
DTC 04 Will Set When

The firing circuit is shorted to voltage.Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.

DIAGNOSTIC TROUBLE CODE (DTC) 05
PASSENGER FIRING CIRCUIT, RESISTANCE TOO HIGH
Open Circuit
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 circuit resistance during this check.
DTC 05 Will Set When

The combined resistance of the passenger airbag
module, the harness wiring, and the connector con-
tacts is above a specified value, as in an open circuit.Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working prop-
erly, the meter’s battery can deploy the airbag and
cause injury.

PASSENGER FIRING CIRCUIT, RESISTANCE TOO LOW
Short Circuit
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 circuit resistance during this check.
DTC 06 Will Set When

The combined resistance of the passenger airbag
module, the harness wiring, and the connector con-
tacts is below a specified value, as in a short circuit
between the wires to the passenger airbag module.Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module side of the connector is not working prop-
erly, the meter’s battery could deploy the airbag and
cause injury.

DIAGNOSTIC TROUBLE CODE (DTC) 07
PASSENGER FIRING CIRCUIT, SHORT TO GROUND
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will diagnose any malfunc-
tions 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 07 Will Set When

The firing circuit is shorted to ground.Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.

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

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.

DIAGNOSTIC TROUBLE CODE (DTC) 09
DRIVER PRETENSIONER CIRCUIT, RESISTANCE TOO HIGH
Open Circuit
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
driver 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.
DTC 09 Will Set When

The combined resistance of the driver pretensioner
module, the harness wiring, and the connector con-
tacts is above a specified value, as in an open circuit.Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
