8B-52 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. Passenger
seat belt pretensioner low terminal 4 is grounded
through a current sink. The current source is connected
to passenger seat belt pretensioner high terminal 3 to
allow a known amount of the current flow. By monitoring
the voltage difference between passenger seat belt
pretensioner high and passenger seat belt pretensioner
low, the SDM calculates the combined resistance of
the passenger seat belt pretensioner inflator module,
the harness wiring, and connector terminal contacts.
DTC 24 Will Set When
DTC 24 will set when the resistance of passenger seat
belt pretensioner deployment loop is below a specified
DIAGNOSTIC TROUBLE CODE (DTC) 24
PASSENGER SEAT BELT PRETENSIONER DEPLOYMENT LOOP
RESISTANCE LOW
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 24. And passenger seat belt
pretensioner deployment loop shutdown.
DTC24 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 passenger seat belt
pretensioner to the SDM terminal 3 or 4. The test for
this DTC is 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.

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.

LUBRICATION
The hood hinges and the locking mechanisms require
periodic lubrication for proper operation. Refer to
Section 0B, General Information for the specific types
and intervals of lubrication.
FASTENERS
Notice: Dissimilar metals in direct contact with each
other may corrode rapidly. Make sure to use the correct
fasteners to prevent premature corrosion.
Many aluminum components are used on current
models. Aluminum in contact with steel may corrode
rapidly if it is not protected by special finishes or
isolators.
The fasteners used have a special finish which provides
adequate protection from corrosion. These special
fasteners differ in color to easily identify them from
the standard metric fasteners, which are medium blue
in color.
When replacing fasteners, avoid substituting otherwise
similar fasteners in the same location.
ANTICORROSION MATERIALS
To provide rust resistance, anticorrosion materials have
been applied to the interior surfaces of most of most
of the metal panels. When servicing these panels,
properly recoat them with a service-type anticorrosion
material if any of the original material has been
disturbed.

DIAGNOSTIC INFORMATION AND PROCEDURE
DIAGNOSIS TEST
Introduction
Using the service connector, possible defects in power section, input output section of internal STICS unit can be
detected and each normal status and defect mode can be checked.
Diagnosis method
1. Use buzzer for diagnosis check status output.
2. Following function outputs should not act when diagnosis switch is ON (STICS in the diagnosis socket box :
connection of No. 7 and ground No. 1)
Tail lamp ON warning (buzzer output stop, door lock/unlock output stop)
Seat belt warning (chime bell output stop)
Central door lock (door lock/unlock output stop)
3. Functions in No. 2 should be restored when diagnosis switch is OFF.
4. Check output should be made once while the diagnosis switch is ON.
5. When inputs are made by operating each different switches more than 2 continuously, make output according
to input order (buzzer ON) and trun off the buzzer for 1 second and than make other remaining outputs for
input switch.
6. Buzzer output is as follows.
T1 : 0.3 ± 0.1 sec.
T2 : 0.3 ± 0.1 sec.
T : 0.6 ± 0.2 sec.
Note:
In case of checking related devices, there will be buzzer sound if it is normal and no buzzer sound if it is
defective.
