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
Intellignet suspension control uses a microcomputer as a
control unit to judge running conditions including engine
revolution from Powertrain Control Module, vehicle speed
from vehicle speed sensor, a brake switch signal, and
vertical and lateral G-sensor signal, then sets optimum
damping force so that best running stability can be
achieved.

2. After this, the warning lamp will be OFF for 3.5
seconds and then will flash each DTC.
a. When there are more than 9 flashes this means
that the indicator is constantly flashing, OFF for
4 seconds ON for 0.5 seconds. In this case there
is no DTC stored in memory.
b. When there are less than 9 flashes you will see
DTC codes in ascending order.
CLEAR DTC
Remark: If you clear the DTC (Diagnosis Trouble Codes)
you will not be able to read any codes recorded during the
last Trouble.
Remark: To be able to use the DTC again to identify a
problem you will need to reproduce the fault or the
problem. This may require a new test drive or just turning
the ignition on (this depends on the nature of the fault).
1. Short the Diagnosis Connector C-39 terminal 3 to
terminal 4 or 5 (ground).
IF it is flashing and the flash is 0.5 seconds ON and 4
seconds OFF without interruption, this means that
there is no DTC. The DTCs are already cleared.
350R200002
2. IF a code is flashed, wait until the lamp is flashing.
3. Conduct brake switch ON/OFF 6 or more times on
condition that one operation is within 2 seconds.
