9A1-2 RESTRAINT CONTROL 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.

RESTRAINT CONTROL SYSTEM 9A1-3

Diagnostic Information
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 for that
application. If the correct part number 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.

Diagnostic Procedures
WARNING: TO AVOID DEPLOYMENT WHEN
TROUBLESHOOTING THE SRS, DO NOT USE
ELECTRICAL TEST EQUIPMENT SUCH AS
A
BATTERY-POWERED OR AC-POWERED
VOLTMETER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN THAT
SPECIFIED IN THIS MANUAL. DO NOT USE A NON-
POWERED, PROBE-TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.
The diagnostic procedures used in this section are
designed to aid in finding and repairing SRS problems.
Outlined below are the steps to find and repair SRS
problems quickly and effectively. Failure to carefull
y
follow these procedures may result in extended
diagnostic time, incorrect diagnosis and incorrect parts
replacement.
1. Perform The “SRS Diagnostic System Check”.
The “SRS Diagnostic System Check” should always be the starting point of any SRS diagnostics. The
“SRS Diagnostic System Check” checks for prope
r
“SRS” warning lamp operation and checks for SRS
trouble codes using both “Flash Code” and “Scan
Tool” Methods.
2. Refer To The Proper Diagnostic Chart As Directed By The “SRS Diagnostic System
Check”.
The “SRS Diagnostic System Check” will lead you to the correct chart to diagnose any SRS problems.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis and incorrect
parts replacement.

3. Repeat The “SRS Diagnostic System Check”
After Any Repair Or Diagnostic Procedures Has
Been Performed.
Performing the “SRS Diagnostic System Check” after all repairs or diagnostic procedures, will assure
that the repair has been made correctly and that no
other conditions exist.

Diagnostic Codes
The SRS control unit maintains a history record of all
diagnostic codes that have been detected since the
SRS codes were last cleared during service.
1. Active Codes - Faults that are presently detected in this ignition cycle. Active codes are stored in RAM
(Random Access Memory).
2. History Codes - All faults detected since the last time the history fault memory was cleared. History codes
are stored in the EEPROM. (Electronically Erasable
Programmable Read only Memory)

How To Read Trouble Codes
All codes (Active and history) can be read (or cleared)
by using a scan tool or equivalent.
If a PDT is not available, have the vehicle serviced by a
HOLDEN dealer.

How To Clear Trouble Codes
Trouble codes can only be cleared by using a Scan
Tool. If a “scan tool” is not available then inform the
owner of the stored codes and suggest that the codes
are cleared upon the next visit to a ISUZU/GM
dealership.

Scan Tool Diagnostics
A scan tool can be used to read current and history
codes and to clear all history codes after a repair is
complete. The scan tool must be updated to
communicate with the SRS through a replaceable
cartridge or a manufacturer's update before it can be
used for SRS diagnostics. To use the scan tool,
connect it to the DLC and turn the ignition switch “ON”.
Then follow the manufacturer's directions fo
r
communication with the SRS. The scan tool reads
serial data from the SRS control unit’s “Serial Data”
output (terminal 21) to the DLC (terminal 2).

1 1. This chart assumes that the “SRS Diagnostic System Check”
and either a symptom chart or a diagnostic trouble code chart
diagnosis has been performed. W hen all circuitry outside the
SRS control unit has been found to operate properly, as
indicated by the appropriate diagnostic chart, and the
symptom or DTC remains current, check the following.
2. Diagnostic procedures must be performed to verify the need
for SRS control unit replacement.
3. Ignition switch is at “LOCK”.
4. Reconnect all SRS components and ensure all components are properly mounted.
5. Ensure the ignition switch has been in the “LOCK” position for
at least 15 seconds.
6. Note the “SRS” warning lamp as the ignition switch is turned
“ON”.
Does the warning lamp flash 7 times then go “OFF”? The symptom or
DTC is no longer occurring.
Clear SRS
diagnostic trouble codes.
Repeat “SRS
Diagnostic System Check” Go to Step 2
2 Using a scan tool, request the diagnostic trouble code display.
Is the same symptom or DTC occurring that was occurring when
the “SRS Diagnostic System Check” was first performed? Go to Step 3 Ignition switch
“LOCK”.
Go to the
appropriate chart for the indicated malfunction.
3 1. Clear the “SRS Diagnostic Trouble Codes”.
2. Ignition switch is in the “LOCK” position for at least two
minutes.
3. Note the “SRS” warning lamp as the ignition switch is turned
“ON”.
Does warning lamp flash 7 times then go “OFF”? SRS is functional
and free of
malfunctions.
No further
diagnosis is required.
Go to Step 4 Ignition switch
“LOCK”.
Replace SRS control unit.
Go to Step 4

7) Apply the windshield sealing adhesive
2.
If you are using an air gun, air pressure should be maintained at 147 - 294 kPa.
After drying the primer completely, apply a sealing adhesive (Sunstar #557 or equivalent) along the edge of the
windshield so that the sealing adhesive has a 20 mm (0.79
in) junction at the middle of the base of the windshield.
Note :
Open time (1 min. or more) should be set after application
of the primer.
Bonding shall be done within 5 minutes after the sealing
adhesive has been applied.


8) Adjust the setting of the windshield with suction discs.
Set the windshield with sealing adhesive applied to the entire circumference on the body panel. Specifically, adjust
the windshield support with the upper molding making
contact with the body panel, press the windshield, and
tighten the windshield support.



9) Use unleaded gasoline and a soft cloth to wipe away any
excess adhesive.
Cure the bonding at a temperature of 20 - 30 °C (68 - 86 °F)
for twenty-four hours.
Check that the windshield does not leak water.
