CURRENT SINK OR SOURCE FAILURE
CIRCUIT DESCRIPTION
During the "Initiator Assembly Resistance Test" the
DERM grounds the "Passenger Side Low" terminal
"87"
and turns "ON" the driver current source at

the "Driver
Side High"terminal "89". The DERM then grounds the
"Driver Side Low" terminal
"88" and turns "ON" the
passenger current source at the "Passenger Side High"
terminal "A7". During each of these tests the DERM
monitors voltage at "Driver Side Low," "Passenger Side
Low," the difference between "Driver Side High" and
"Driver Side Low" and the difference between
"Passenger Side High" and "Passenger Side Low."
When the measured values are outside the expected
range DTC 28 is set.
DTC WILL SET WHEN
The voltage measured at "Driver Side Low" or
"Passenger Side Low'' is below a specified value while its
respective initiator resistance is
in range or when the
voltage measured at "Driver Side
Low" or "Passenger
Side Low" 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 checks whether malfunction is in the wiring
harness. The wiring harness malfunction would be a
high resistance rather than an open. An open would
set a different diagnostic trouble code.
3. This test determines whether the malfunction is in
the wiring harness. The wiring harness malfunction
would be a high resistance rather than an open.
An
open would set a different diagnostic trouble code
DIAGNOSTIC AIDS
An intermittent condition is likely to be caused by a poor
wire to terminal connection
in CKT 1 B18C or CKT 1836.
When a scan tool
"Clear Codes" command is issued and
the malfunction is still present, the DTC will not reappear
for ten minutes or until the next ignition cycle.

SERVICE PRECAUTIONS
CAUTION: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW
THE PROCEDURES LISTED BELOW TO
TEMPORARILY
DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS
REPAIRS.
The DERM in Driver-Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 2
minutes after the ignition switch is turned to
"OFF," the
battery is disconnected, or the fuse powering the DERM
is removed.
Many of the service procedures require removal of the
"AIR BAG" fuse, and disconnection of the inflator
modules from the deployment loop to avoid an accidental
deployment.
If the inflator module is disconnected from
the deployment loop as noted in the "Disabling the
SRS"
procedure that follows, service can begin immediately
without waiting for the 2 minute time period to expire.
DISABLING THE SRS
REMOVAL
• Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
• Turn the ignition switch to "OFF"
1. Remove SRS fuse C-21, C-22, C-23 and C-24 from
left dash side lower fuse block.
2. Disconnect yellow
3-way connector at the base of
the steering column.
3. Remove
liP compartment door assembly, Refer to
"Passenger inflator module replacemenf' in section
9J-135.
4. Disconnect yellow 4-way connector behind the liP
compartment door assembly.
NOTE
• With the" AIR BAG" fuse removed and ignition switch
"ON," the "AiR BAG" warning lamp will be "ON." This
is normal operation and does not indicate
an SRS
malfunction.
ENABLING THE SRS
INSTALLATION
Turn ignition switch to "LOCK" and remove key.
1. Connect yellow 4-way connector of passenger
inflator module.
2. Install liP compartment door assembly, Refer to
"Passenger inflator module replacement" in section
9J-3.
3. Connect yellow 3-way connector at the base of the
steering column.
4. Install" AIR BAG" fuse C-21, C-22, C-23 and C-24 to
left dash side lower fuse block.
Tum ignition switch to
"RUN" and verify that the "AIR
BAG"
warning lamp flashes seven times and then turns
"OFF" If it does not operate as described, perform the
"SRS Diagnostic System Check" in section 9J-32.
HANDLING/INSTALLATION/DIAGNOSIS
1. Inflator modules should not be subjected to
temperatures above 65°C(150°F).
2. Discriminating s~nsors, inflator modules, arming
sensors, or DERMs should not be used if they have
been dropped from a height of 1
00 centimeters (3.28
feet) or more.
3. When a discriminating sensor or arming sensor is
replaced, it MUST be oriented with the arrow
on the
sensor pointing toward the front of the vehicle.
It is
very important for the discriminating sensors and
arming sensor to be located flat on the mounting
surface, parallel to the vehicle datum line.
It is
important that the sensor mounting surface is free of
any dirt or other foreign material.
4. Do not apply power to the SRS unless all
components are connected or a diagnostic chart
requests it, as this
will set a diagnostic trouble code.
5. The
"SRS Diagnostic System Check'' must be the
starting point of any SRS diagnostics. The
"SRS
Diagnostic System Check" will verify proper "AIR
BAG" warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
INSPECTIONS REQUIRED AFTER ACCI­
DENT
CAUTION: CERTAIN SRS COMPONENTS MUST BE
REPLACED AFTER A FRONTAL
CRASH INVOLVING
AIR
BAG DEPLOYMENT.
In all types of accident regardless of "Air Bag"
deployment, visually inspect all the following
components and their points and replace as required:
- Passenger
Inflator Module
- Steering wheel
- SRS coil assembly
- Steering column
- Knee bolster and
Instrument panel mounting

9J-118 Supplemental Restraint System
attachments
- Driver seat and belt
- Passenger seat and belt
- Dual Pole Arming
Sensor
-Discriminating Sensors
-DERM
The sensor replacement policy specifies mandatory
replacement of the sensors, after crash involving
AIR
BAG deployment. If AIR BAG has not been deployd,
Replace the sensors
in the area of accident damage only.
The
"area of accident damage" is defined as that area of
the vehicle which is crushed, bent ,or damaged in other
ways. An example might be a front-end collision
in which
the forward portions of the vehicle have contacted
another vehicle, tree, guardrail,etc.
In this example,
1)
If AIR BAG has deployed, All Sensor should be
replaced.
2)
If AIR BAG has not deployed, replace the sensors
in the area of accident damage only.
sensor(s) on the radiator tie bar would require
replacement, since that portion of the vehicle was
damaged in the accident. The Dual Pole Arming Sensor
would not require mandatory replacement. Of course, if
the DERM sets a code and the diagnostic chart leads to
a faulty sensor that was not in the area of accident
damage, that sensor should also be replaced.Sensors
in
the area of accident damage should be replaced even if
those sensors do not appear to be damaged. Do not
attempt to determine whether a sensor is
OK-ALWAYS
replace it if it is in the area of accident damage.Aiso, if a
sensor is
in an area of accident damage,but the SRS has
NOT been deployed,replace the sensor.The sensor
bracket may be slightly bent,wiring may be
damaged, etc., and the sensor might not work properly
in
another collision. Again, do not attempt to determine
whether a sensor is
OK --ALWAYS replace it if it is in
the area of accident damage. Also,
inspect
SRS coil assembly wiring and steering
wheel for any signs of scorching, melting, or damage due
to excessive heat.
If the coil assembly wire or steering ~
wheel is damaged, replace them. The steering column
and wheel must be dimensionally checked to determine
if they are damaged. Refer to
in this Section 3 of this
manual.
Never use
SRS parts from another vehicle. This does not
include remanufactured parts purchased from an
authorized
ISUZU Dealer; they may be used for SRS
repairs.
Do not attempt to repair the forward discriminating
sensors ,the dual pole arming senor, the DERM, the
SRS
coil assembly, the inflator modules, the steering wheel, or
the steering column. Service of these items is
replacement only.
Verify replacement part numbers.
