"AIR BAG" WARNING LAMP COMES "ON" STEADY
CIRCUIT DESCRIPTION
When the ignition switch is first turned "ON," "Ignition 1"
voltage is applied from the "C-21" fuse to "Redundant
Indicator Ignition 1 ,"terminal "B2", and to the "AIR BAG"
warning lamp which is connected to "SRS Indicator,"
terminal "B1". The "C-22·C-23" fuses apply system
voltage to the
"Ignition 1" inputs, terminals "A9" and
"A10". The DERM responds by flashing the "AIR BAG"
warning lamp 7 times. If "Starter" is outside of the normal
operating voltage range, the
"AIR BAG" warning lamp
will
come "ON" solid with no DTCs set. When the engine
is being cranked,
"Ignition 1" voltage is applied from the
"C-1" fuse to the DERM at the "Crank" input. The DERM
responds by grounding the
"SRS" Indicator" output until
"Starter" voltage is removed from the "Crank'' input. This
results in the
"AIR BAG" warning lamp being "ON" during
cranking.After cranking, the DERM
will flash the "AIR
BAG" warning lamp 6 times.
CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic table.
1. An open "C-22-C-23" fuses would cause the "AIR
BAG" warning lamp to come "ON" steady.
2. A disconnected DERM harness connector will cause
the warning
lamp to come "ON" steady via the
shorting clip from terminal "A1" to terminal "81".
3. This test checks whether the short to ground caused
the
"C-1" fuse to open.
4. This test checks for an open in the ground circuitry
to the DERM.
5. This test determines whether the short to ground is
due to a malfunctioning dual pole arming sensor or
a short
in the wiring.
6. This test checks for an open in the "Ignition 1"
circuitry to the DERM.
7. This test checks for a short from the "SRS Indicator''
circuit to ground.
8. This test checks for a short from the "Crank" input
circuit to 8+.

DTC 15
PASSENGER INITIATOR CIRCUIT RESISTANCE HIGH
CIRCUIT DESCRIPTION
During the "Initiator Assembly Resistance Test" the
DERM grounds the
"Driver Side Low" terminal "BB" and
turns "ON" the passenger current source at the
"Passenger Side High" terminal "A7". This causes a
known amount of current to
flow through the passenger
initiator circuit. By monitoring the difference between the
voltage at the "Passenger Side High" terminal "A7" and
the "Passenger
Side Low" terminal "B7" the DERM
calculates the combined resistance of the passenger
inflator module, harness wiring CKTs IB21, IB22 and
IB24 and connector terminal contact.
DTC WILL SET WHEN
The combined resistance of the passenger inflator
module,
harness wiring CKT's IB21, IB22, and IB24 and
connector
terminal contact is above a specified value.
This test is run once each ignition cycle during the
"Initiator Assembly Resistance Tesf' 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 ignition switch is turned "OFF."
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test determines whether the malfunction is in
the passenger inflator module circuitry or in the
DERM wiring harness circuitry.
3. This test determines whether the malfunction is an
open in CKT's IB"21, IB22, IB24.
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a poor
connection to the passenger
inflator module terminal "2"
or terminal "3" or a poor connection to the DERM at
terminal "A7''. 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.
