11. This chart assumes that the “SRS Diagnostic System Check”
and either a symptom chart or a diagnostic trouble code chart
diagnosis have been performed. When all circuitry outside the
SDM has been found to operate properly, as indicated by the
appropriate diagnostic chart, and the symptom or DTC
remains current, the following
2. Diagnostic procedures must be performed to verify the need
for SDM replacement.
3. Ignition switch “OFF”.
4. Reconnect all SRS components, ensure all components are
properly mounted.

Service Precaution
WARNING: IF SO EQUIPPED 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 “AUTO CRUISE” 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
“AUTO CRUISE” 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.
