DTC 22 Driver 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” “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 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
DTC 22.
DTC Will Clear When:
The ignition switch is turned “OFF.”
DTC Chart Test Description:
Number(s) below refer to circled number(s) on the
diagnostic chart:

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”.
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 yellow 2–pin connector at the base of the
steering column.
5. This test isolates the malfunction to one side of the
SRS coil assembly yellow 2–pin connector located
at the base of steering column.
6. This test determines whether the open is in the
wiring.
7. This test determines whether the malfunction is in
the SRS coil assembly or the driver air bag
assembly.
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at the driver air bag assembly harness 2–pin
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

compressor neck using O-ring remover J-9553-01.
8. Recheck the shaft and inside of the compressor
neck for dirt or foreign material and be sure these
areas are perfectly clean before installing new parts.
Cleaning
Thoroughly clean O-ring seal groove in front head.
CAUTION: Seals should not be re-used. Always use
a new specification service seal on rebuild. Be sure
that the seal to be installed is not scratched or
damaged in anyway. Make sure that the seal seat
and seal are free of lint and dirt that could damage
the seal surface or prevent sealing.
Installation
1. Dip the new seal seat O-ring (1) in clean 525
viscosity refrigerant oil and assemble onto O-ring
installer J-33011.2. Insert the O-ring installer J-33011 into the
compressor neck until the installer "bottoms". Lower
the moveable slide of the O-ring installer to release
the O-ring into the seal O-ring lower groove (The
compressor neck top groove is for the shaft seal
retainer ring.) Rotate the installer to seat the O-ring
and remove the installer.
3. Dip the new seal in clean 525 viscosity refrigerant oil
and assemble seal to Seal Installer J-23128-A, by
turning handle clockwise. The stamped steel case
side of the lip seal must be engaged with knurled
tangs of installer so that flared-out side of lip seal is
facing and installed towards the compressor. Install
seal protector J-34614, in the seal lip and place over
the compressor shaft, and push the seal in place with
a rotary motion or place the seal protector J-34614
over end of compressor shaft, and slide the new seal
onto the shaft with a rotary motion until it stops. Take
care not to dislodge the O-ring. Be sure the seal (2)
makes good contact with the O-ring. Disengage the
installer from the seal and remove the installer
J-23128-A and the seal protector J-34614.
CAUTION: Handling and care of seal protector is
important. If seal protector is nicked or the bottom
flared, the new seal may be damaged during
installation.
4. Install the new seal retainer ring with its flat side
against the Seal, using Snap-Ring Pliers. Use the
sleeve from O-ring installer J-33011 to press in on
the seal retainer ring so that it snaps into its groove.
5. To leak test, install compressor leak test fixture
J-39893 on rear head of compressor and connect
gage charging lines and Refrigerant Recovery

COMPRESSOR OIL
Compressor Oil Check
The oil used to lubricate the compressor is circulating
with the refrigerant.
Whenever replacing any component of the system or a
large amount of gas leakage occurs, add oil to maintain
the original amount of oil.
Checking and Adjusting Oil Quantity for
Used Compressor
1. Perform oil return operation. Refer to Oil Return
Operation in this section.
2. Discharge and recover refrigerant and remove the
compressor.
3. Drain the compressor oil and measure the extracted
oil with a measuring cylinder.
4. If the amount of oil drained is much less than 90 cc
(3.0 fl. oz.), some refrigerant may have leaked out.
Conduct a leak tests on the connections of each
system, and if necessary, repair or replace faulty
parts.
5. Check the compressor oil contamination. (Refer to
Contamination of Compressor Oil in this section.)
6. Adjust the oil level following the next procedure
below.7. Install the compressor, then evacuate, charge and
