RESTRAINT CONTROL SYSTEM
DTC 16 Passenger Deployment loop Resistance Low
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 Bag Low” terminal “16” is grounded
through a resistor and the passenger current source
connected to “Passenger Bag High” terminal “15” allows a
known amount of current to flow. By monitoring the
voltage difference between “Passenger Bag High” and
“Passenger Bag Low”, the SDM calculates the combined
resistance of the passenger air bag assembly, harness
wiring IB07–YEL/GRN and IB08–YEL/RED connector
terminal contact.
DTC Will Set When:
The combined resistance of the passenger air bag
assembly, harness wiring IB07–YEL/GRN and
IB08–YEL/RED, 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.”
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 connection of the yellow 2–pin
connector.
4. This test cheeks for proper operation of the shorting
clip in the yellow 2–pin connector.
5. The test checks for a malfunction passenger air bag
assembly.
6. This test determines whether the malfunctioning is
due to shortening in the wiring.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
between IB07–YEL/GRN and IB08–YEL/RED, or a
malfunctioning shorting clip on the passenger air bag
assembly which would require replacement of the air bag
assembly. The test for this diagnostic trouble code is only
run while “AIR BAG” warning lamp is performing the bulb
