DRIVER INITIATOR CIRCUIT RESISTANCE LOW
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
IB19 and connector terminal contact is above a specified
value. This test is run during the
"Initiator Assembly
Resistance
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
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. DTC 16 and 22 will set simultaneously when the
"Driver Side High" circuit due to parallel current
paths.
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
bulb check. When a scan tool
"Clear Codes" command
is issued and the malfunction is
still present, the DTC will
not reappear until the next ignition cycle.

DTC 24 {PAGE 1 OF 3)
INITIATOR CIRCUIT VOLTAGE LOW
' I,
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
"Driver Side Low" terminal "88" and "Passenger Side
Low" terminal "87" to detect shorts or opens within the
driver deployment
loop. When the measured voltage at
terminal "88" or "87" is below a specified percentage of
its respective Driver 36 VLR power
supply voltage for
500 milliseconds DTC 24 is set.
DTC WILL SET WHEN
The voltage measured at "Driver Side Low" terminal "88"
is below a specified percentage of "Driver 36 VLR" or
when the
voltage measured at "Passenger Side Low"
terminal "87" is below a specified percentage of
"Passenger 36 VLR" for 500 milliseconds. This test is run
during the "Continuous Monitoring" test.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
a diagnostic
trouble code.
DTC WILL CLEAR WHEN
The voltage measured at "Driver Side Low" terminal "88"
is within a specified percentage of "Driver 36 VLR" and
the
voltage measured at "Passenger Side Low" terminal
"87"
is within a specified percentage of "Passenger 36
VLR" for 500 milliseconds.
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test determines whether the malfunction is
occurring
in the steering column circuitry.
3. This test determines whether the malfunction is
occurring
in the passenger inflator module circuitry.
4. This test check's for a short from the SRS COIL to
ground.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a poor
connection at DERM terminals
"A3" and "A4", dual pole
arming sensor terminals "2", "4", "5" or"7",water intrusion
in any discriminating sensor, an open in CKT 1810 or
CKT 1815, ora short to ground in CKT's 1810,1815, 1816,
1817, 1818,
1819, 1820, 1821, 1822, 1824, 1825, 1836.
Refer to DTC 25 diagnose a possible short to B+. When
the malfunction occurs during
an ignition cycle DTC 24
will set. If the malfunction is present at the beginning of
the next ignition
cycle DTC 25 will set and DTC 24 will be
moved to a history
file.

INITIATOR CIRCUIT SHORT TO IGNITION
CIRCUIT DESCRIPTION
During the "Initiator Assembly Resistance Test" the
DERM grounds the
"Driver Side Low" terminal "BB" and
measures the voltage at "Driver Side Low" and
"Passenger Side Low." The DERM then grounds
"Passenger Side Low" terminal "B7" and again measures
the
voltage at "Driver Side Low" and "Passenger Side
Low."
For a properly operating circuit the voltage
measures the voltage measurements during each of
these tests
will be below a specified value. When the
voltages measured at both "Driver Side Low" and
"Passenger
Side Low'' are above a specified value during
both tests
DTC 25 is set.
DTC WILL SET WHEN
The voltages measured at both "Driver Side Low" and
"Passenger
Side Low" are above a specified value while
the DERM attempts to ground each of these terminals.
This test is run during the
"Initiator Assembly Resistance
Test" and the "1 0 Minute Loop Test" when: 1) "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 either "Driver Side Low" or
"Passenger
Side Low" is below a specified value while
the DERM ground either of these terminals.

DRIVER INITIATOR CIRCUIT OPEN
CIRCUIT DESCRIPTION
When there is an open in the driver inflator module or the
SRS coil assembly the resistance between "Driver Side
High" terminal "89" and "Driver Side Low" terminal "88"
increases. This causes a larger voltage drop from the
"Driver
Side High" to the "Driver Side Low" across a
resistor inside the DERM which connects these two
terminals together. The increase in the voltage difference
between "Driver
Side High" and "Driver Side Low" is
detected by the DERM during the "Continuous
Monitoring" tests and DTC 26 is sets.
DTC WILL SET WHEN
The voltage difference between "Driver Side High"
terminal "89" and "Driver Side Low" terminal "88" is
above or
equal to a specified value for 500 milliseconds.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
