1. Disconnect the battery negative cable.
2. Wait 1 minute for the SDM capacitor to discharge.

The capacitor supplies reserve power to deploy
the passenger side airbag even if the battery
has been disconnected.

3. Visually inspect the supplemental inflatable

restraints (SIR) wiring harness.

Is there any visible damage to the SIR wiring
harness?

1. Disconnect the electrical connector for the

passenger airbag module.

2. Disconnect the electrical connector at the SDM.

The shorting bar at the disconnected SDM
connector will create a complete circuit be-
tween the wires from the passenger airbag
module.

3. Use a multimeter to check the voltage at one of

the terminals on the SDM side of the SIR wiring
harness connector for the passenger airbag
module.

Refer to ‘‘Diagnostic Illustration 10’’ in this
section.

Is the voltage greater than the specified value?

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
module-side of the connector is not working prop-
erly, the meter’s battery can deploy the airbag and
cause injury.

DIAGNOSTIC TROUBLE CODE (DTC) 10

DRIVER PRETENSIONER 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 driver
pretensioner circuit. The SDM allows a very small
amount of current to flow through the pretensioner cir-
cuit. The SDM monitors the circuit resistance during this
check.

DTC 10 Will Set When

The combined resistance of the driver pretensioner
the harness wiring, and the connector contacts is be-
low a specified value, as with a short circuit between
the wires to the driver airbag module.

Test Description

Caution: Never measure the resistance of an airbag
module with an ohmmeter. An ohmmeter’s battery
can deploy the airbag and cause injury.
