Service Precaution
WARNING: THIS VEHICLE HAS 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 PCM. When a signal from the control
switch is input to the PCM while the vehicle is in this state,
the cruise control system is activated. 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 speed stored.
2.Coast±Down Function: When the SET/COAST
switch is kept on while the vehicle is 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.

2 . RESUME/ACCEL Switch Function
1.Resume Function: When the RESUME, ACCEL
switch is turned on/off after the system is temporarily
deactivated by pressing the brake or clutch pedal
while the vehicle is running, the vehicle resumes, the
speed stored before the system was released.
2.Accelerate Function: When the RESUME/ACCEL
switch is kept on after the system is released
completely, the vehicle accelerates its speed during
that time. The vehicle speed at which the vehicle was
running when the switch was turned off is stored in the
memory, and the vehicle automatically returns to this
speed.
3.Tap±Up Function: When the RESUME/ACCEL
switch is turned on and off instantaneously while the
vehicle is running, the vehicle accelerates a mile for
each on/off operation. The vehicle speed at which the
vehicle was running when the switch was turned off
last is stored in the memory, and the vehicle
automatically returns to this stored speed.
3 . CANCEL Function
1.Temporary Cancellation:
When the cancel switch is turned on.
When the brake pedal is pressed.
When the clutch pedal is pressed. (M/T)
When the select lever is shifted to any position other
than ªDº, ª3º, ª2º or ªLº. (A/T)
When the vehicle speed has decreased about 12.5
mph (20 km/h) or more than the stored speed.
When the vehicle speed gets lower than 22.5 mph
(36 km/h).
2.Complete Cancellation:
When the starter switch or the main switch is turned
off.
When the failsafe function is activated.

Diagnosis
Cruise control system is controlled by the PCM as well as
6VE1 engine and automatic transmission. DTC codes are
stored in the PCM if troubles occur in the circuit. DTC
codes categorized ªtype Dº are shown only by the Tech 2
scan tool. The following chart only shows some typical
DTCs for cruise control system. Refer to
PCM Diagnostic
Trouble Codes in Driveability and Emissions for entire
DTC diagnosis.
