8B – 32 SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
DRIVER PRETENSIONER CIRCUIT, RESISTANCE TOO LOW
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
D 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.
DIAGNOSTIC TROUBLE CODE (DTC) 10
Short 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 with an ohmmeter. An ohmmeter's battery
can deploy the airbag and cause injury.
