8B-50 SUPPLEMENTAL RESTRAINTS SYSTEM
Circuit Description
When the ignition switch is turned to ON, the sensing
and diagnostic module (SDM) will perform tests to
diagnose critical malfunctions within SDM itself. Upon
passing these tests ignition and deployment loop
voltages are measured to ensure that they are within
their respective normal voltage ranges. The SDM then
proceeds with resistance measurement test. Driver seat
belt pretensioner low terminal 7 is grounded through a
current sink. The current source is connected to driver
seat belt pretensioner high terminal 6 to allow a known
amount of the current flow. By monitoring the voltage
difference between driver seat belt pretensioner high
and driver seat belt pretensioner low, the SDM
calculates the combined resistance of the driver seat
belt pretensioner inflator module, the harness wiring,
and connector terminal contacts.
DTC 23 Will Set When
DTC 23 will set when the resistance of driver seat belt
pretensioner deployment loop is below a specified

value (1.4 ± 0.5 Ω). The test is run once each ignition
cycle during the resistance measurement test when
the ignition voltage is above a specified value.
Action Taken
The SDM will turn on the airbag indicator (blink mode
4) and set DTC 23. And driver seat belt pretensioner
deployment loop shutdown.
DTC23 Will Clear When
The ignition switch is turned OFF or the scan tool
CLEAR CODES command is received.
Diagnostic Aids
All intermittent condition is likely to be the caused by
a poor connection from the driver seat belt pretensioner
to the SDM terminal 6 or 7. The test for this DTCis run
only while the airbag indicator is performing the start-
up test. When a scan tool CLEAR CODES command
is issued and the malfunction is still present, the DTC
will not reappear until next ignition cycle.

DTC 23 - Driver Seat Belt Pretensioner Deployment Loop Resistance Low
Caution: The sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the airbags
and pretensioners for 0.15 seconds after the ignition
is OFF and the fuse has been removed. If the airbags
or pretensioners are not disconnected, do not begin
service until one minute has passed after
disconnecting power to the SDM. Otherwise, injury
could result.Caution: During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.
Never power the supplemental restraints system
(SRS) when the SDM is not rigidly attached to the
vehicle. Also SDM mounting nuts must be carefully
tightened to ensure proper operation of the SRS.
The SDM could be activated if it is powered when it
is not rigidly attached to the vehicle, resulting in
unexpected deployment and possible injury.

ON-VEHICLE SERVICE
SERVICE PRECAUTION
Caution: The sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the airbags
and pretensioner for 0.15 seconds after the ignition
is OFF and the airbag fuse has been removed. If the
airbags or pretensioners are not disconnected, do
not begin service until one minute has passed after
disconnecting power to the SDM. If the airbag are
disconnected, service can begin immediately without
waiting for one-minute time period to expire. Failure
to temporarily disable the SRS during service can
result in unexpected deployment, personal injury,
and otherwise unneeded SRS repairs.
DISABLING THE SUPPLEMENTAL
RESTRAINT SYSTEM (SRS)
1. Turn the steering wheel to the straight-ahead
position.
2. Turn the ignition switch to LOCK and remove the key.
3. Remove the airbag fuse F31 in the I/P fuse block
and wait more than one minute for SRS capacitor to
discharge.
ENABLING THE SUPPLEMENTAL
RESTRAINT SYSTEM (SRS)
Enabling the supplemental restraint system (SRS) is
reverse order of “Disabling the Supplemental Restraint
System (SRS)”.
Caution: Staying well away from the inflator
modules, turn the ignition key switch to ON, and
verify that the airbag indicator illuminates for 4.5
seconds and turns OFF. If it does not operate as
described, perform the “SRS Diagnostic System
Check” referring in this section.
HANDLING, INSTALLATION AND
DIAGNOSIS
Airbag modules should not be subjected to
temperature above 65°C (149°F)
An airbag module or sensing and diagnostic module
(SDM) should not be used if it has been dropped
from height of 0.9 meters (3 feet) or greater.
It is very important for the SDM to be installed flat
on the mounting surface, parallel to the vehicle’s
longitudinal axis.
To avoid setting diagnostic trouble codes (DTCs),
do not apply power to the SRS unless all components
are connected or a diagnostic chart request it.
The SRS Diagnostic System Check must be the
starting point of any SRS diagnostics. The SRS
Diagnostic System Check will verify proper airbag
indicator operation and will lead you to correct chart
to diagnose any SRS malfunctions. Bypassing
these procedures may result in extended diagnostic
time and incorrect parts replacements.
REPAIRS AND INSPECTIONS
REQUIRED AFTER AN ACCIDENT
Caution: any repairs to the vehicle’s structure must
return it to the original production configuration.
Deployment requires replacement of SDM, the
inflator modules, and a dimensional inspection of
the steering column.
If any SRS components are damaged, they must
be replaced. If SRS components mounting points
are damaged, they must be repaired or replaced.
Never use SRS parts from another vehicle. This does
not include remanufactured parts purchased from
an authorized source.
Do not attempt to service the SDM, the clock spring,
or other airbag modules, these items must be
replaced if they are defective.
Verify the part number of replacement airbag
modules. Some inflator modules look identical but
contain different internal components.
ACCIDENT WITH DEPLOYMENT -
COMPONENTS REPLACEMENT
All SRS components must be replaced after frontal crash
involving airbag deployment. After deployment, a
powdery residue may be on the surface of the airbag.
The powder consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-products of the
chemical reaction. Sodium hydroxide dust (similar to
lye soap) is produced as a by-product of the deployment
reaction. The sodium hydroxide then quickly reacts with
atmospheric moisture and is converted to sodium
carbonate and sodium bicarbonate (also known as
baking soda). Therefore, it is unlikely that sodium
hydroxide will be present after deployment. Replace
the following SRS components.
Caution: Wear gloves and safety glasses during the
disposal procedure. Refer to “Deployed Airbag
Module Disposal Procedure” in this section.

Removal and installation Procedure
1. Disconnect the negative battery cable.
Caution: The SDM can maintain sufficient
voltage to deploy the airbags for 0.15 seconds
after the Ignition is OFF and the airbag fuse has
been removed. If the airbags are not
disconnected, service cannot begin until one
minute has passed after disconnecting power
to the SDM. If the airbags are disconnected,
service can begin immediately without waiting
for one-minute time period to expire. Failure to
temporarily disable the SRS during service
result in unexpected deployment, personal
injury, and otherwise unneeded SRS repair.
2. Disable the supplemental restraint system (SRS).
Refer to “Disabling the SRS” in this section.
3. Position the steering wheel straight ahead.
4. Remove the driver airbag module mounting bolts.
Installation Notice
Caution: When handling an airbag module,
always keeps the top of the unit facing upward.
This leaves room for the airbag to expand if the
module unexpectedly deploys. Without room
for expansion, a module suddenly propelled
toward a person or object can cause injury or
vehicle damage.
5. Remove the connector from the horn terminal and
the driver airbag module.
6. Remove the driver airbag module.
7. Installation should follow the removal procedure
in the reverse order.
