5–8840–2421–0 SRS Driver/Passenger
Load Tool
901RS146The SRS Driver/Passenger Load Tool 5–8840–2421–0 is
used only when called for in this section. It is used as a
diagnostic aid and safety device to prevent inadvertent air
bag assembly deployment.
The load tool has three yellow connectors attached to its
case.
The three small connectors are electrically functional and
serve as resistive load substitutions.
No more than two connectors are used at any time. One
of the small connectors is used to substitute for the load of
the driver air bag assembly when it is connected at the top
of the column to the SRS coil assembly. Another small
connector is used to substitute for the load of the driver air
bag assembly and the SRS coil assembly when it is
connected at the base of the column to the SRS wiring
harness. The third small connector is used to substitute
for the load of the passenger air bag assembly and
pretensioner seat belt assembly when connected to the
passenger air bag assembly and pretensioner seat belt
assembly harness connector.
By substituting the resistance of the load tool when called
for, a determination can be made as to whether an inflator
circuit component is causing system malfunction and
which component is causing the malfunction. The loadtool should be used only when specifically called for in the
diagnostic procedures.
NOTE: If comand to use 5–8840–2421–0 load tool when
repair the pretensioner seat belt, connect load tool

Service Precautions for SRS
Component Service
CAUTION: When fasteners are removed, always
reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use
the correct part number fastener for that application.
If the correct part number fastener is not available, a
fastener of equal size and strength (or stronger) may
be used. fasteners that are not reused, and those
requiring thread locking compound will be called
out. The correct torque value must be used when
installing fasteners that require it. If the above
conditions are not followed, parts or system damage
could result.
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver–Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 15
seconds after the ignition switch is turned “OFF,” the
battery is disconnected, or the fuse powering the SDM is
removed.
Many of the service procedures require removal of the
“C–21” fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected from
the deployment loop as noted in the “Disabling the SRS”
procedure that follows, service can begin immediately
without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to “OFF” and turn the steering
wheel so that the vehicle’s wheels are pointing straight
ahead.
1. Remove SRS fuse “C–21” from left dash side lower
fuse block or disconnect battery.
2. Disconnect yellow 2–pin connector at the base of
steering column.
3 . R e m o v e g l o v e b o x a s s e m b l y ; R e f e r t o “ P a s s e n g e r a i r

connector behind the glove box assembly.
CAUTION: W i t h t h e “ C – 2 1 ” f u s e r e m o v e d a n d
ignition switch “ON,” the “AIR BAG” warning lamp
will be “ON.” This is normal operation and does not
indicate an SRS malfunction.
Enabling The SRS
Installation
Turn ignition switch to “LOCK” and remove key.
1. Connect yellow 2–pin connector passenger air bag
assembly.2. Install glove box assembly. Refer to “Passenger Air
Bag Assembly Replacement” in this section.
3. Connect yellow 2–pin connector at the base of the
steering column.
4. Install “AIR BAG” fuse “C–21” to left dash side lower
fuse block or connect battery.
Turn ignition switch to “ON” and verify that the “AIR BAG”
warning lamp turn on 3.5 seconds and then turns “OFF.” If
it does not operate as described, perform the “SRS
Diagnostic System Check” in this section.
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM is replaced, it must be oriented with the
arrow on the SDM pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as
this will set a diagnostic trouble code.
5. The “SRS Diagnostic System Check” must be the
starting point of any SRS diagnostics. The “SRS
Diagnostic System Check” will verify proper “AIR
BAG” warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
Inspections Required After An Accident
CAUTION: C e r t a i n S R S c o m p o n e n t s m u s t b e

DTC 29 Passenger Pretensioner Loop Short To Ground
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.
The SDM monitors the voltages at “Driver Belt Low”
terminal “10” and “Passenger Belt Low” terminal “22” to
detect short to ground in the pretensioner assembly
circuits.
DTC Will Set When:
Neither of the air bag and the pretensioner belt are open.
“Ignition 1” is within the normal operating voltage range.
Once these conditions are met and the voltage at
“Passenger Belt Low” is below a specified value, DTC 29
will set. This test is run once each ignition cycle and
“Continuous Monitoring”.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets a
diagnostic trouble code.
DTC Will Clear When:
This malfunction is no longer occurring and the ignition
switch is turned “OFF”.
DTC Chart Test Description:
Number(s) below refer to circled number(s) on the
diagnostic chart.
2. This test determines whether the SDM is
malfunctioning.
3. This test isolates the malfunction to one side of the
passenger pretensioner assembly yellow 2–pin
connector at the base of the passenger seat.
4. This test determines whether the malfunction is in
IB15–BLU/BLK.
5. This test determines whether the malfunction is in
IB16–BLU/ORG.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to ground in the passenger pretensioner assembly circuit.
Inspect IB15–BLU/BLK and IB16–BLU/ORG carefully for
cutting or chafing. If the wiring pigtail of the passenger
pretensioner assembly is damaged, the component must
be replaced.

DTC 31 Passenger Pretensioner 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”. “Passenger Belt Low” terminal “10” is grounded
through a resister and the passenger current source
connected to “Passenger Belt High” terminal “9” allows a
known amount of current to flow. By monitoring the
voltage difference between “Passenger Belt High” and
“Passenger Belt Low” the SDM calculates the combined
resistance of the passenger air bag assembly, harness
wiring IB15–BLU/BLK and IB16–BLU/ORG connector
terminal contact.
DTC Will Set When:
The combined resistance of the passenger pretensioner
assembly, harness wiring IB15–BLU/BLK and
IB16–BLU/ORG, 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 proper connection of the yellow
2–pin connector.
4. This test checks for proper contact and/or corrosion
of the yellow 2–pin connector terminals.
5. The test checks for a malfunctioning passenger
pretensioner assembly.
6. This test determines whether the malfunction is due
to high resistance in the wiring.
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at the passenger air bag assembly harness
connector terminals “1” and “2”, SDM terminal “9” and
“10”, or a poor wire to terminal connection in
IB15–BLU/BLK and IB16–BLU/ORG. This test for this
