8B-40  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 19 Will Set When

DTC 19 will set when the resistance of driver seat belt
pretensioner deployment loop is above specified value

DIAGNOSTIC TROUBLE CODE (DTC) 19

DRIVER SEAT BELT PRETENSIONER DEPLOYMENT LOOP

RESISTANCE HIGH

(4.5 ± 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 19. And driver seat belt pretensioner
deployment loop shutdown.

DTC19 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.

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

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.
