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
RESTRAINT CONTROL SYSTEM 9J1–24
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at terminals “1” and “2” of the SRS coil 2–pin
connector at the base of the steering column, terminal “1”
and “2” of the driver air bag assembly 2–pin connector at
the top of the steering column, SDM terminals “3” and “4”
or a poor wire to terminal connection in IB05–YEL orIB06–YEL/BLK. The test for this diagnostic trouble code
is only run while the “AIR BAG” warning lamp is
performing the bulb check, unless DTC 17 or DTC 26 is
detected. When a scan tool “Clear Codes” command is
issued and the malfunction is still present, the DTC will not
reappear until the next ignition cycle.

Retrials from 2WD to 4WD :In cold weather or under

the indicator lamp inform driver of this incident as

on the fly system).
Diagnosis
Before Judging That Troubles Occur
(Unfaulty mode)
When Switching from 2WD to 4WD
1.In case that blinking frequency of the 4WD
indicator changes from 2Hz to 4Hz.
When heavy synchronization load is needed, the
motor actuator tries the shifting transfer gear three
times including the activation shifting. While the
motor actuator tries shifting, the indicator blinks by
2Hz. If the third shifting fails, the indicator’s blinking
changes from 2Hz to 4Hz at the same time that the
motor actuator shifted back to 2WD.
Heavy synchronization load occurs by:
extremely lower temperature.
higher speed, rotation difference of wheels during
cornering.
Solution 1: Operate again after stop the vehicle or
slow down.
2.In case that the 4WD indicator continues blinking
by 2Hz for more than 11.5 seconds.
When there is rotation difference of wheels or there
is phase difference between front wheels and axles,
it is difficult to connect front wheels to front axles. The
blinking by 2Hz shows that shifting the transfer gear
or connecting the front wheels is in the middle of
operating. In above case, the indicator’s blinking by
2Hz shows that connecting the front wheels is not
completed (because the indicator’s blinking changes
to 4Hz when the shifting transfer gear is impossible.).
And removal of rotation or phase difference make
connecting the front wheels possible.
Solution 2: When vehicle is running, drive
straight ahead while accelerating and
decelerating. When vehicle is at a stop, move the
vehicle forward and backward from 2 to 3 meters.When switching from 4WD to 2WD
1.In case that the 4WD indicator continues blinking
by 2Hz .
The 4WD indicator continues blinking by 2Hz until
both shifting the transfer gear and disconnecting the
front wheels are completed when switching 4WD to
2WD. When driveline is loaded with torsional torque,
the shifting transfer gear and disconnecting front
wheels are impossible. In this case, removal of
torsional torque on driveline make the shifting
transfer gear and disconnecting front wheels
possible.
Solution 3: When vehicle is running, drive
straight ahead while accelerating and
decelerating. When vehicle is at a stop, move the
vehicle forward and backward from 2 to 3 meters.
2.In case that the 4WD indicator’s blinking changes
from 2Hz to 4Hz.
Check the position of transfer lever. Is it at “4L”
position? In view of the shifting mechanism of
transfer, the gear shifting from 4WD to 2WD at “4L”
condition is impossible.
Solution 4: Push the 4WD switch to 4WD, shift the
transfer lever to “High” position and re–operate
the 4WD switch to 2WD.
