NOTE Defined
A NOTE statement immediately precedes or follows an operating procedure, maintenance practice or condition that
requires highlighting. A NOTE statement also emphasises necessary characteristics of a diagnostic or repair procedure.
A NOTE statement is designed to:
• Clarify a procedure,
• Present additional information for accomplishing a procedure,
• Give insight into the reasons for performing a procedure in the recommended manner, and / or
• Present information that gives the technician the benefit of past experience in accomplishing a procedure with
greater ease.
1.2 System Components
The main components of the electronic cruise control system are:
• cruise control ON / OFF switch (in dash panel).
• cruise control switch assembly (incorporated into wiper and washer switch assembly),
• instrument cluster assembly (cruise set lamp),
• clutch pedal switch assembly (manual transmission vehicles only),
• stop lamp switch assembly,
• powertrain interface module (PIM),
• engine control module (ECM),
• throttle actuator control (TAC) assembly, and
• electrical wiring (incorporated into the main wiring harness).

3 W ith the aid of an assistant, monitor the voltage on the multimeter and press and release the clutch pedal.
• With the clutch pedal in the rest position, the multimeter
should display battery voltage
• W ith the clutch pedal pressed, the multimeter should
display 0 V
Does the multimeter display as described? Go to Step 31 Check for a blown

9A-4 SUPPLEMENTAL RESTRAINT SYSTEM
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 A SERVICE ON, OR NEAR, THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING A 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 UNNECESSARY 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/GM will call out those fasteners that require
a replacement after removal. ISUZU/GM will also
call out the fasteners that require thread lockers o
r
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
CAUTION: When fasteners are removed, always
reinstall them at the same location from which
they were removed. If a fastener needs to be
replaced, use the correct part number fastener fo
r
that application. If the correct part numbe
r
fastener is not available, a fastener of equal size
and strength (or stronger) may be used.
Fasteners that are not reused, and those requiring
thread locking compound will be called out. The
correct torque value must be used when installing
fasteners that require it. If the above conditions
are not followed, parts or system damage could
result.

Restraint Devices





RTW 79ASH000801
Legend
(1) Deployed Air Bag
(2) Knee Bolster
(3) Seat Belt


The Supplemental Restraint System (SRS) helps
supplement the protection offered by the driver and
front passenger seat belts by deploying an air bag
from the center of the steering wheel and from the
front of the passenger side of the instrument panel.
The air bag deploys when the vehicle is involved in a
frontal crash of sufficient force up to 30 degrees off the
centerline of the vehicle. To further absorb the crash
energy there is a knee bolster located beneath the
instrument panel for both the driver and passenger,
and the steering column is collapsible.
