CRUISE CONTROL SYSTEM 8E-23
Cruise Control Actuator Assembly (with Con-
trol Module)
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Disconnect connector from actuator assembly (2) (with con-
trol module).
3) Remove actuator cap (1) from actuator assembly (2).
4) Disconnect cruise cable (3) from actuator assembly (2).
5) Remove actuator assembly (2) from vehicle.
INSPECTION
Move actuator lever (1) by hand and check its operation as
described below.
1) Actuator lever (1) should not turn clockwise.
2) Actuator lever (1) should turn smoothly by about 1/3 rotation
counterclockwise and contact internal stopper.
3) When hand is taken off from actuator lever (1) at the position
in 2) above, it should return to its original position (2) by
return spring force. If actuator lever (1) does not operate as
described above, replace it.
INSTALLATION
Install actuator assembly by reversing removal procedure, noting
the following point.
•Adjust cruise cable play to specification referring to “CRUISE
CABLE PLAY INSPECTION AND ADJUSTMENT” in this
section. CAUTION:
Never disassemble cruise control actuator assembly.
Disassembly will spoil its original function.

10B-6 AIR BAG SYSTEM
Diagnosis
Diagnostic Trouble Code (DTC)
The AIR BAG DIAGNOSTIC SYSTEM CHECK must always be the starting point of any air bag system diagno-
sis. The AIR BAG DIAGNOSTIC SYSTEM CHECK checks for proper “AIR BAG” warning lamp operation and
checks for air bag diagnostic trouble codes (DTCs) using on-board diagnosis function or SUZUKI scan tool.
Use of Special Tool
You should be familiar with the tools listed in this section under the heading SPECIAL TOOLS. You should be
able to measure voltage and resistance. You should be familiar with proper use of a scan tool such as Air Bag
Driver/Passenger Load Tool, Connector Test Adapter Kit and the Digital Multimeter.
Special tool
(A) : 09932-75020 (Connector Test Adapter Kit)
This must be used whenever a diagnostic procedure requests
checking or probing a terminal.
Using the appropriate adapter in the special tool will ensure that
no damage to the terminal will occur from the multimeter probe,
such as spreading or bending.
The adapter will also give an idea of whether contact tension is
sufficient, helping to find an open or intermittent open due to poor
terminal contact. WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equip-
ment 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.
