8B–22 SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
DAEWOO M-150 BL2
D1AB302B
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
D 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.
