7) When refrigerant container (3) is emptied, use following proce-
dure to replace it with a new refrigerant container (3).
a. Close low pressure valve.
b. Replace empty container (3) with a refrigerant container
which has been charged with refrigerant. When using refrig-
erant container tap valve (4), use following procedure for re-
placement.
i) Retract needle (1) and remove refrigerant container tap
valve (4) by loosening its plate nut (2).
ii) Install previously-removed refrigerant container tap valve
(4) to a new refrigerant container (3).
c. Purge any air existing in center charging hose.
When using refrigerant container tap valve, use following
procedure to purge air.
i) Once fully tighten refrigerant container tap valve and then
loosen (open) plate nut slightly.
ii) Open low pressure valve of manifold gauge set a little.
iii) As soon as refrigerant comes out with a ªhissº through a
clearance between refrigerant container and tap valve,
tighten plate nut as well as manifold gauge set low pres-
sure valve.
iv) Turn handle of tap valve clockwise so that its needle is
screwed into the new container to make a hole for refriger-
ant flow.

INSPECTION
Pump Body, Cover, Side Plate and Shaft
Check sliding surfaces of each part for wear and damage.
If any defect is found, replace pump assembly.
Cam Ring
Check vane sliding surface of cam ring for wear and damage.
If any defect is found, replace pump assembly.
Rotor and Vane
Check sliding surfaces of rotor and vane for wear and damage.
Check clearance between rotor and vane.
Clearance: Standard 0.015 mm (0.0006 in.)
Limit 0.027 mm (0.0011 in.)
Replace pump assembly if any defect is found in above checks.
Relief Valve (Flow Control Valve) and Its Spring
Check fluid passage of relief valve and orifice of connector for ob-
struction (clogged).
Check sliding surface of relief valve for wear and damage.

ABS HYDRAULIC UNIT/CONTROL MODULE
ASSEMBLY
ABS control module is a component of ABS hydrauli unit / control
module assembly and has the following functions.
Self-Diagnosis Function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time and
indicates the results (warning of abnormality occurrence and DTC)
through the ªABSº warning lamp as described below.
1) When ignition switch is turned ON, ªABSº warning lamp lights for
2 seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in good
condition), ªABSº warning lamp turns OFF after 2 seconds.
3) When the vehicle starts to move after the ignition switch is turned
ON (more than one wheel speed sensor signals are inputted),
solenoid valves and motor of ABS hydraulic unit operate once
one after another for electrical check.
During this check, motor operation sound may be heard but that
means nothing abnormal.
4) When an abnormality in the system is detected, ªABSº warning
lamp lights and the area where that abnormality lies is stored in
the memory of EEPROM in ABS control module.
5) When Diag. switch terminal of diagnosis connector (monitor
connector) is grounded, the abnormal area is output as DTC. It
is indicated by flashing of ªABSº warning lamp. (Refer to the
table below. )

For procedure to clear all DTC's, refer to the item ªDiagnostic
Trouble Code Clearanceº in this section.
Also ABS control module turns ON EBD warning lamp (brake warn-
ing lamp) depending on the trouble that detected by the module and
EBD warning lamp does not indicate DTC as well as ªABSº warning
lamp.
Fail-Safe Function
When an abnormality occurs (an abnormal DTC is detected), ABS
control module turns OFF the fail-safe relay which supplies power
to ABS hydraulic unit. Thus, with ABS not operating, brakes func-
tion just like the brake system of the vehicle not equipped with ABS.

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 ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº 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 ªService Precau-
tionsº under ªOn-Vehicle Serviceº 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
ªLOCKº 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).
