DISCRIMINATING SENSOR INTERCONNECT PEN
CIRCUIT DESCRIPTION
During the "Initiator Assembly Resistance Test" the
DERM grounds the "Driver
Side Low" terminal "88" and
measures the voltage at "Driver Side Low" and
"Passenger Side Low." The DERM then grounds
"Passenger Side Low" terminal "87" and again measures
the voltage at "Driver
Side Low" and "Passenger Side
Low."For a properly operating circuit the voltage
measurements during each of these tests will be below
a specified value. When the voltage measured at either
"Driver
Side Low" or "Passenger Side Low," but not both,
is above a specified value during either test
DTC 18 is
set.
DTC WILL SET WHEN
The voltage measured at either "Driver Side Low" or
"Passenger
Side Low," but not both, is above a specified
value
while the DERM attempts to ground either of these
terminals. This test is run during the
"Initiator Assembly
Resistance
Tesf' and the "1 o Minute Loop Test" when: 1)
No "higher priority faults" are detected during "Turn-ON,"
2) No "higher priority faults" are detected during
"Continuous Monitoring" for one second, 3) No "Crank"
signal present, 4) "Ignition 1" voltage is above a specified
value.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
a diagnostic trouble code.
DTC WILL CLEAR WHEN
The voltages measured at both "Driver Side Low" and
"Passenger
Side Low" are below specified value while
the DERM grounds each of the terminals.

PASSENGER INITIATOR CIRCUIT VOLTAGE HIGH
CIRCUIT DESCRIPTION
During normal, non-deployment operation of the SRS,
a small amount of current flows through both the driver
and passenger deployment loops. The diagnostic
resistors within the dual pole arming sensor and the
discriminating sensors
along with the resistance of the
inflator modules cause voltage drops within the
deployment loops. The DERM monitors the voltage at
"Passenger
Side Low" terminal "87" to detect shorts or
opens within the passenger deployment
loop. When the
measured
voltage is above a specified percentage of
"Passenger 36
VLR" for 500 milliseconds DTC 19 is set.
DTC WILL SET WHEN
The voltage measured at "Passenger Side Low'' terminal
"87''
is above a specified percentage of "Passenger 36
VLR" for 500 milliseconds and DTC 35 is not set. This
test is
run every 100 milliseconds during the "Continuous
Monitoring" tests.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
a diagnostic
trouble code.
DTC WILL CLEAR WHEN
The voltage measured at "Passenger Side Low" terminal
"87"
is within a specified percentage of "Passenger 36

500 milliseconds.
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. DTC 19 and 23 together means that there is both
open Forward
Sensor LH and Forward Sensor RH,
or internal short in dual pole arming sensor.
3. This test checks for decreased resistance in driver
side diagnostic resistors of the
dual pole arming
sensor.
4. This test checks for decreased resistance in the
passenger side diagnostic resistors of the
dual pole
arming sensor.
5. This test determines whether the malfunction is in
the Forward
Sensor RH/LH circuitry.
7. This test determines whether the malfunction is in
the FORWARD SENSOR RH/LH ENG, ROOM
HARNESS or FORWARD SENSOR RHILH.
1
o. This test determines whether the malfunction is in
the
FORWARD SENSOR RH/LH.
DIAGNOSTIC AIDS
An open between the passenger inflator module and the
forward discriminating sensor causes the
voltage to
increase at "Passenger Side Low'' due to the loss of a
ground path. This
also causes the voltage to decrease at
"Driver Side Low" due to decreased current flow through
the discriminating sensor network.
Intermittent condition
is
likely to be caused by backed out shorted terminals on
the arming sensor harness connector, poor connection
at any of the discriminating sensor terminals.

DRIVER INITIATOR CIRCUIT RESISTANCE HIGH
CIRCUIT DESCRIPTION
During the "Initiator Assembly resistance Test" the
DERM grounds the
"Passenger Side Low" terminal "B7"
and turns "ON" the driver current source at

the
"Driver
Side
High" terminal "B9". This causes a known amount
of Current to flow through the driver initiator circuit. By
monitoring the difference between the voltage at the
"Driver Side High" terminal "B9" and the "Driver Side
Low'' terminal "B8" the DERM calculates the combined
resistance of the driver inflator module, SRS coil
assembly, harness wiring CKTs IB16, IB17 and IB19 and
connector terminal contact.
DTC WILL SET WHEN
The combined resistance of the driver inflator module,
SRScoilassembly, harness wiring
CKT's IB16, IB17 and
IB19 and connector terminal contact is above a specified
value. This test is run during the
"Initiator Assembly

CIRCUIT DESCRIPTION
During the "Initiator Assembly resistance Test" the
DERM grounds the "Passenger
Side Low" terminal "B7"
and turns "ON" the driver current source at the "Driver
Side High" terminal "B9". This causes a known amount
of current to flow through the driver initiator circuit. By
monitoring the difference between the voltage at the
"Driver Side High" terminal "B9" and the "Driver Side
Low"
terminal "B8" the DERM calculates the combined
resistance of the driver inflator module, SRS coil
assembly, harness wiring CKTs IB16, IB17 and IB19 and
connector terminal contact.
DTC WILL SET WHEN
The combined resistance of the driver inflator module,
SRS coil assembly, harness wiring CKT's IB16, IB17 and

3. This test determines whether the malfunction is in
the driver inflator module circuitry or in the DERM
wiring harness circuitry.
4. This test checks for a short from the "Driver Side
High"
circuit to the "Driver Side Low'' circuit.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a short
between CKT
IB17 and CKT IB16 or CKT IB19 or a
malfunctioning shorting
clip at the base of the steering
column. The test for this diagnostic trouble code is only
run while the "AIR BAG" warning lamp is performing the
