8B – 46 SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
D1AB302B
DIAGNOSTIC TROUBLE CODE (DTC) 18
CONNECTION BETWEEN DRIVER FIRING CIRCUIT AND DRIVER
PRETENSIONER CIRCUIT
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
airbag and 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 18 Will Set When
D Connection between the driver firing circuit and the
driver pretensioner circuit or the SDM internal connection problem may exist.
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 disconnected. 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 properly, the meter’s battery can deploy the airbag and
cause injury.
