RESTRAINT CONTROL SYSTEM
DTC 34 Passenger Pretensioner 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
pretensioner loop voltages are measured to ensure they
are within their respective normal voltage ranges. During
“Continuous Monitoring” diagnostics, a fixed amount of
current is flowing in the deployment loop. This produces
proportional voltage drops in the loop. By monitoring the
voltage difference between “Passenger Belt High” and
“Passenger Belt Low”, the SDM calculates the combined
resistance of the passenger pretensioner assembly,
harness wiring IB15–BLU/BLK AND IB16–BLU/ORG,
and connector terminal contact.
DTC Will Set When:
The voltage difference between “Passenger pretensioner
High” terminal “9” and “Passenger pretensioner Low”
terminal “10” 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 “Passenger Belt High”
terminal “9” and “Passenger Belt Low” terminal “10” isbelow a specified value for 500 milliseconds during
“Continuous Monitoring”.
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the malfunction is in
the SDM.
3. This test verifies proper connection of the yellow
2–pin connector.
4. This test cheeks for proper contact and/or corrosion
of the shorting clip in the yellow 2–pin connector
terminals.
5. The test checks for a malfunctioning passenger
pretensioner assembly.
6. This test determines whether the open in the wiring.
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at the passenger pretensioner assembly
harness connector terminals“1” and “2”, SDM terminals
“9” and “10”, or an open in IB15–BLU/BLK and
IB16–BLU/ORG.

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 then proceeds with the “Resistance
Measurement Test” “Driver Belt Low” terminal “22” is
grounded through a current sink and the driver current
source connected to “Driver Belt High” terminal “21”
allows a known amount of current to flow. By monitoring
the voltage difference between “Driver Belt High” and
“Driver Belt Low”, the SDM calculates the combined
resistance of the driver pretensioner assembly, harness
wiring IB13–BLU/RED and IB14–BLU/YEL, and
connector terminal contact.
DTC Will Set When:
The combined resistance of the driver pretensioner
assembly, harness wiring IB13–BLU/RED and
IB14–BLU/YEL, and connector terminal contact is above
a specified value. This test 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
DTC 41.
DTC Will Clear When:
The ignition switch is turned “OFF”.
