RESTRAINT CONTROL SYSTEM
DTC 45 Driver Pretensioner Loop Short To Ground
D09RW014
Circuit Description:
When the ignition switch is turned ªONº, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests, ªIgnition 1º, and
pretensioner loop voltages are measured to ensure they
are within their respective normal voltage ranges.
The SDM monitors the voltage at ªDriver Belt Lowº
terminal ª22º and ªpassenger Belt Lowº terminal ª10º to
detect shorts to ground in the air bag assembly circuits.
DTC Will Set When:
Neither of the air bag and the pretensioner belt are open.
ªIgnition 1º is within the normal operating voltage range.
This test is run once each ignition cycle and ªContinuous
Monitoringº. Once these conditions are met and the
voltage at ªDriver Belt Lowº is below a specified value,
DTC 45 will set.
Action Taken:
SDM turns ªONº the ªAIR BAGº warning lamp and sets a
diagnostic trouble code.
DTC Will Clear When:
The malfunction is no longer occurring and the ignition is
turned ªOFFº.
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the SDM is
malfunctioning
3. This test isolates the malfunction to one side of the
driver pretensioner assembly yellow 2±pin
connector at the base of the driver seat.
4. This test determines whether the malfunction is in
IB13±BLU/RED.
5. This test determines whether the malfunction is in
IB14±BLU/YEL.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to ground in the driver pretensioner assembly circuit.
Inspect IB13±BLU/RED and IB14±BLU/YEL carefully for
cutting or chafing.

DTC 46 Driver Pretensioner Loop Short To Voltage
D09RW014
Circuit Description:
When the ignition switch is turned ªONº, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests, ªIgnition 1º, and
pretensioner loop voltages are measured to ensure they
are within their respective normal voltage ranges.
The SDM monitors the voltage at ªDriver Belt Lowº
terminal ª22º and ªPassenger Belt Lowº terminal ª10º to
detect shorts to B+ in the pretensioner assembly circuits.
DTC Will Set When:
ªIgnition 1º is in the normal operating voltage range. This
test is run once each ignition cycle and ªContinuous
monitoringº. Once these conditions are met and the
voltage at ªDriver Belt Lowº is above a specified value,
DTC 46 will set.
Action Taken:
SDM turns ªONº the ªAIR BAGº warning lamp and sets
DTC 46.
DTC Will Clear When:
The malfunction is no longer occurring and the ignition is
turned ªOFFº.
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the SDM is
malfunctioning.
3. This test isolates the malfunction to one side of the
driver pretensioner assembly yellow 2±pin
connector at the base of the driver seat.
4. This test determines whether the malfunction is in
IB13±BLU/RED.
5. This test determines whether the malfunction is in
IB14±BLU/YEL.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to B+ in the driver pretensioner assembly circuit. Inspect
IB13±BLU/RED and IB14±BLU/YEL carefully for cutting
or chafing. If the wiring pigtail of the driver pretensioner
assembly is damaged, the components must be
replaced. A careful inspection of IB13±BLU/RED and
IB14±BLU/YEL, including the driver pretensioner
assembly is essential to ensure that the replacement
SDM will not be damaged.

Service Precaution
WARNING: I F S O E Q U IPPED WITH A
SUPPLEMENTAL RESTRAINT SYSTEM (SRS),
REFER TO THE SRS COMPONENT AND WIRING
LOCATION VIEW IN ORDER TO DETERMINE
WHETHER YOU ARE PERFORMING SERVICE ON OR
NEAR THE SRS COMPONENTS OR THE SRS
WIRING. WHEN YOU ARE PERFORMING SERVICE
ON OR NEAR THE SRS COMPONENTS OR THE SRS
WIRING, REFER TO THE SRS SERVICE
INFORMATION. FAILURE TO FOLLOW WARNINGS
COULD RESULT IN POSSIBLE AIR BAG
DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.
General Description
The cruise control keeps the vehicle running at a fixed
speed until a signal canceling this fixed speed is received .
When the main switch ªAUTO CRUISEº is turned on with
the vehicle in the running mode, the battery voltage is
applied to the control unit. When a signal from the control
switch is input to the control unit while the vehicle is in this
state, the cruise control actuator is activated to operate
the system. Also, while the system is operating, the
ªAUTO CRUISEº indicator light in the meter assembly
lights up.
1. SET/COAST Switch Function
1.Set Function: When the SET/COAST switch is
pressed and released with the main switch on, the
speed at which the vehicle is running at that moment
is stored in the memory, and the vehicle automatically
runs at the stored speed.
2.Coast-down Function: When the SET/COAST
switch is kept on while the vehicle in running, the
vehicle decelerates during that time. The speed at
which vehicle is running when the control switch is
turned off is stored in the memory, and the vehicle
automatically returns to the stored speed.
3.Tap-down Function: When the SET/COAST switch
is turned on and off instantaneously while the vehicle
is running, the vehicle decelerates a mile for each
on/off operation. The vehicle speed at which the
vehicle was running when the SET/COAST was
turned off last is stored in the memory, and the vehicle
automatically returns to this stored speed.
