DTC 26 Driver Deployment Loop Open
D09RW014
Circuit Description:
When the ignition switch is turned “ON”, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests, “Ignition 1”, and
deployment loop voltages are measured to ensure they
are within their respective normal voltage ranges.
During “Continuous Monitoring” diagnostics, a fixed
amount of current is following in the deployment loop.
This produces proportional voltage drops in the loop. By
monitoring the voltage difference between “Driver Bag
High” and “Driver Bag Low”, the SDM calculates the
combined resistance of the driver air bag assembly, SRS
coil assembly, harness wiring IB05–YEL and
IB06–YEL/BLK, and connector terminal contact.
DTC Will Set When:
The voltage difference between “Driver Bag High”
terminal “3” and “Driver Bag Low” terminal “4” is above or
equal to a specified value for 500 milliseconds during
“Continuous Monitoring”.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets a
diagnostic trouble code.
DTC Will Clear When:
The voltage difference between “Driver Bag High”
terminal “3” and “Driver Bag Low” terminal “4” is below aspecified value for 500 milliseconds during “Continuous
Monitoring”.

connector terminals “1” and “2” at the top of the steering
column, SRS coil assembly harness 2–pin connection
terminals “1” and “2”, SDM terminals “3” and “4”, or an

DTC 29 Passenger Pretensioner Loop Short To Ground
D09RW014
Circuit Description:
When the ignition switch is turned “ON”, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests, “Ignition 1”, and
pretensioner loop voltages are measured to ensure they
are within their respective normal voltage ranges.
The SDM monitors the voltages at “Driver Belt Low”
terminal “10” and “Passenger Belt Low” terminal “22” to
detect short to ground in the pretensioner assembly
circuits.
DTC Will Set When:
Neither of the air bag and the pretensioner belt are open.
“Ignition 1” is within the normal operating voltage range.
Once these conditions are met and the voltage at
“Passenger Belt Low” is below a specified value, DTC 29
will set. This test is run once each ignition cycle and
“Continuous Monitoring”.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets a
diagnostic trouble code.
DTC Will Clear When:
This malfunction is no longer occurring and the ignition
switch is turned “OFF”.
DTC Chart Test Description:
Number(s) below refer to circled number(s) on the
diagnostic chart.
2. This test determines whether the SDM is
malfunctioning.
3. This test isolates the malfunction to one side of the
passenger pretensioner assembly yellow 2–pin
connector at the base of the passenger seat.
4. This test determines whether the malfunction is in
IB15–BLU/BLK.
5. This test determines whether the malfunction is in
IB16–BLU/ORG.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to ground in the passenger pretensioner assembly circuit.
Inspect IB15–BLU/BLK and IB16–BLU/ORG carefully for
cutting or chafing. If the wiring pigtail of the passenger
pretensioner assembly is damaged, the component must
be replaced.

DTC 31 Passenger Pretensioner Loop Resistance High
D09RW014
Circuit Description:
When the ignition switch is turned “ON”, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests “Ignition 1”, and
deployment loop voltages are measured to ensure they
are within their respective normal voltage ranges. The
SDM then proceeds with the “Resistance Measurement
Test”. “Passenger Belt Low” terminal “10” is grounded
through a resister and the passenger current source
connected to “Passenger Belt High” terminal “9” allows a
known amount of current to flow. By monitoring the
voltage difference between “Passenger Belt High” and
“Passenger Belt Low” the SDM calculates the combined
resistance of the passenger air bag assembly, harness
wiring IB15–BLU/BLK and IB16–BLU/ORG connector
terminal contact.
DTC Will Set When:
The combined resistance of the passenger pretensioner
assembly, harness wiring IB15–BLU/BLK and
IB16–BLU/ORG, and connector terminal contact is
above a specified value. This test is run once each
ignition cycle during the “Resistance Measurement Test”
when:
1. No “higher priority faults” are detected during
“Turn–ON”,
2. “Ignition 1” voltage is in the specified value.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets a
diagnostic trouble code.
DTC Will Clear When:
The ignition switch is turned “OFF.”

of the yellow 2–pin connector terminals.
5. The test checks for a malfunctioning passenger
pretensioner assembly.
6. This test determines whether the malfunction is due
to high resistance in the wiring.
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at the passenger air bag assembly harness
connector terminals “1” and “2”, SDM terminal “9” and
“10”, or a poor wire to terminal connection in
IB15–BLU/BLK and IB16–BLU/ORG. This test for this
