Service Precaution
When servicing air conditioning system, note the following instructions.
Refrigerant line
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When connecting hoses and pipes, apply a few drops of compressor oil to seats of coupling nuts and O-ring.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.

DTC C1063 (DTC 63) – ABS Fail Safe Circuit
DESCRIPTION
The ABS control module monitors the voltage at the terminal of the solenoid circuit constantly with the ignition
switch turned ON. Also, immediately after the ignition switch is turned “ON”, perform an initial check as follows.
Switch the fail safe transistor in the order of ON → OFF → ON and check if the voltage at 6 solenoid circuit ter-
minals changes to High → Low → High. If anything faulty is found in the initial check and when the voltage at all
solenoid circuit terminals is low with the ignition switch turned ON and ABS not operated, this DTC will be set.

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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” 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:
Whether the following systems (parts) are used in the particular vehicle or not depends on vehicle
specifications. Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor(s) or CO adjusting resistor
Three-way catalytic converter (TWC) and warm up three-way catalytic converter (WU-TWC)

General Description
Battery
The battery has three major functions in the electrical system.
It is a source of electrical energy for cranking the engine.
It acts as a voltage stabilizer for the electrical system.
It can, for a limited time, provide energy when the electrical
load exceeds the output of the generator.
CARRIER AND HOLD-DOWN
The battery carrier should be in good condition so that it will sup-
port the battery securely and keep it level.
Before installing the battery, the battery carrier and hold-down
clamp should be clean and free from corrosion and make certain
there are no parts in carrier.
To prevent the battery from shaking in its carrier, the hold-down
bolts should be tight enough but not over-tightened.
ELECTROLYTE FREEZING
The freezing point of electrolyte depends on its specific gravity.
Since freezing may ruin a battery, it should be protected against
freezing by keeping it in a fully charged condition. If a battery is
frozen accidentally, it should not be charged until it is warmed.
SULFATION
If the battery is allowed to stand for a long period in discharged
condition, the lead sulfate becomes converted into a hard, crystal-
line substance, which will not easily turn back to the active mate-
rial again during the subsequent recharging. “Sulfation” means
the result as well as the process of that reaction.
Such a battery can be revived by very slow charging and may be
restored to usable condition but its capacity is lower than before.
