6. Clutch pedal engagement height inspection:
1. Operate the parking brake lever and block the
wheels.
2. Start the engine, fully step on the clutch pedal,
and move the shift lever to 1st position.
3. With the engine idling, release the clutch pedal
slowly and measure its stroke just prior to its
clutching position.

MIN. 30 mm (1.18 in)
7. If the measured value exceeds the specified limit,
check the following points. Repair if necessary:

Hydraulic circuit for fluid leakage or air in circuit.

Clutch disc warped.

Diaphragm spring weakened or tip of fingers worn.

Driven plate sticking on sprines.

Removal
1. Disconnect the battery ground cable.
2. Remove the instrument panel driver lower cover(5).
Refer to the Instrument Panel Assembly in Body
Structure section.
3. Remove seven screws to remove the steering
cowl(4).
4. Disconnect the SDM (air bag controller) connector
located at lower of the instrument panel driver lower
cover.
5. Remove four fixing screws and disconnect the driver
inflator module connector to remove the driver inflator
module(3).
CAUTION: When carrying a live inflator module,
make sure the bag opening is pointed away from
you. In case of an accidental deployment, the bag will
then deploy with minimal chance of injury. Never
carry the inflator module by the wires or connector
on the underside of the module.
When placing a live inflator module on a bench or
other surface, always face the bag and trim cover up,
away from the surface. This is necessary so that a
free space is provided to allow the air bag to expand
in the unlikely event of accidental deployment.
6. Remove the steering wheel(2).
Refer to the Steering Wheel in Steering section.
7. Disconnect the SRS coil assembly connector,
remove four fixing screws to remove the SRS coil
assembly(1).
8. Disconnect the lighting switch connector, remove four
fixing screws to remove the lighting switch(6).

Installation
To install, follow the removal steps in the reverse order,
noting the following points.1. Check to see if the vehicle is in the straight driving
condition and turn the rotary section of the SRS coil
assembly provided to the upper surface of the lighting
switch (combination switch) counterclockwise fully
until it stops.
Then from where it stops, turn it back about 3
rotations to set the alignment marks(7) together
before installing the steering wheel.

2. Tighten the steering shaft nut to the specified torque.
Torque: 34 N·m (3.5 kg·m/25 lb ft)
3. When connect the double lock type of inflator module
connector, insert the connector completely and lock
at outside.
Imperfect locking may cause malfunction of SRS
system circuit.
4. When installing the steering cowl(11), be sure to pass
the harnesses through the route as shown in the
figure so that the starter switch harness(8), the
combination switch harness(9) and inflator module
harness(10) will not get caught.

Anti-lock Brake System (ABS)
General Description
The circuit consists of EHCU (Electronic Hydraulic
Control Unit), wheel speed sensor, GÐsensor,
stoplight switch or brake switch (w/cruise control),
backup light switch, transmission switchÐ1, 2,
indicator light and data link connector.
EHCU controls brake fluid pressure applied to front
and rear wheels to prevent wheels from locking by
using speed sensor and GÐsensor signals.
Based on wheel speed signals from speed sensor,
EHCU activates solenoid valves incorporated into
the control unit to increase, maintain or decrease
brake fluid pressure.
Refer to AntiÐlock Brake System in Brakes section.

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.
