HEATING, VENTILATION AND AIR CONDITIONING (HVAC)
Automatic Air Conditioning System
General Description
Using a variety of sensors, this automatic air conditioner
accurately senses outside air temperature, solar
radiation quantity, evaporator's blowing temperature, and
interior temperature, then enters these data to the
automatic air conditioner control unit (equipped with the
built-in micro-computer). The data provided to the control
unit enables to automatically control blow temperatureand blow air quantity, turn on or off the compressor and
switch the blow port as well as switching between the
fresh air intake and interior air circulation.
Resetting the automatic function allows you to switch to
the manual control mode.
The self-diagnoisis function of the automatic air
conditioner control unit (with the built-in micro-computer)
allows the unit to access and diagnose a failed part easier
and quicker.

Ultrasonic Leak Detector
1. J 41413 EVAP Pressure/Purge Diagnostic Station is
a multipurpose tool which is used to perform several
diagnostic procedures for enhanced emission
testing. The station will accommodate a nitrogen gas
filled cylinder which is used to pressurize the vehicle
EVAP system for a leakdown test and leak location
test when a vehicle is repaired for leakage in the
enhanced evaporative emission control system. It
also has two additional gauges (inches of mercury
and inches of water) which are used to measure both
source vacuum and EVAP canister purge vacuum to
verify correct operation and vapor flow within the
canister purge circuit.
2. J 41416 Ultrasonic Leak Detector is a
microprocessor-based device used to detect leaks in
the enhanced evaporative emission control system.
The evaporative system is pressurized to 30 inches of
water using the J 41413 EVAP Pressure/Purge
Diagnostic System. Small leaks in the EVAP system
will emit sound at a high frequency undetectable by a
human ear but detectable with the J 41416. The
technician traces along the evaporative system and
can pinpoint leaks due to corroded lines, cracked
hoses, or a damaged EVAP component. The
detector includes a high quality set of headphones to
block out surrounding shop noise and the LED
sensitivity meter allows a visual reference for locating
leaks in conjunction with the audio output heard
through the headphones. Powered by (1) nine volt
battery.

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
fasteners joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fasteners.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.
