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

CIRCUIT DESCRIPTION
DATA AREA FULL
ACTION TAKEN
When there is a frontal crash of sufficient force to activate
the dual pole arming sensor and at least one of the two
discriminating sensors simultaneously,
DTC 51 is set. At
this time the DERM
will record information regarding SIR
system status and vehicle status in EEPROM. DTC 52
will set when the DERM has stored information regarding
eight frontal crash events.
DTC WILL SET WHEN
The DERM attempts to store frontal crash information
and finds the
EEPROM data area full. This test is run
each time the DERM stores or attempts to store
information regarding a frontal crash event. DERM
turns
"ON" the "AIR BAG" warning lamp and sets
a diagnostic trouble code.
DTC WILL CLEAR WHEN
A scan tool "Clear Codes" command is received by the
DERM.
If, at the next ignition "ON" after receiving a

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.
CAUTION: PROPER OPERATION OF THE
SENSORS AND SUPPLEMENTAL RESTRAINT
