DTC 21 Driver Deployment 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” “Driver Bag Low” terminal “4” is
grounded through a current sink and the driver current
source connected to “Driver Bag High” terminal “3” allows
a known amount of current to flow. 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 combined resistance of the driver air bag assembly,
SRS Coil assembly, harness wiring IB05–YEL and
IB06–YEL/BLK, 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 21.
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 proper connection of the yellow
2–pin connector at the base of the steering column.
4. This test checks for proper contact and/or corrosion
of the 2–pin connector terminals at the base of
steering column.
5. This test isolate the malfunction to one side of the
SRS coil assembly yellow 2–pin connector located
at the base of the steering column.
6. This test determines whether the malfunction is due
to high resistance in the wiring.
7. This test determines whether the malfunction is in
the SRS coil assembly or the driver air bag
assembly.

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.
