SECTION 3B1
POWER STEERING (P/S) SYSTEM
WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed informa-
tion, refer to the description of POWER STEERING GEAR BOX COMPONENTS under REMOVE AND
INSTALL POWER STEERING GEAR BOX.
All steering gear fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and / or could result in major repair expense. They must be replaced with one of the
same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of these parts.
Although the figures in this section show only the left-hand steering vehicle, the same work procedure
and data apply to the right-hand steering vehicle.
