On-Vehicle Service
Precautions
When connector are connected to ABS hydraulic unit/control
module assembly, do not disconnect connectors of sensors and
turn ignition switch ON. Then DTC will be set in ABS control mod-
ule.
ABS Hydraulic Unit Operation Check (Using
SUZUKI Scan Tool)
1) Connect SUZUKI scan tool to data link connector (DLC) (1)
with ignition switch OFF.
Special tool
(A) : SUZUKI scan tool
2) Turn ignition switch to ON position and check actuator opera-
tion using “HYDRAULIC CONTROL TEST” under “miscella-
neous test” (“MISC. TEST”) mode of SUZUKI scan tool.
ABS Hydraulic Unit Operation Check
(Not Using Suzuki Scan Tool)
1) Check that basic brake system other than ABS is in good
condition.
2) Check that battery voltage is 11V or higher.
3) With “ABS” warning lamp, check that no abnormality is
detected in ABS. Refer to “DIAGNOSTIC TROUBLE CODE
(DTC) CHECK” in this section.
4) Lift up vehicle.
5) Set transmission to neutral and release parking brake.
6) Turn each wheel gradually by hand to check if brake drag-
ging occurs. If it does, correct.
7) With diag. switch terminal (2) of diagnosis connector (1) con-
nected to ground by using service wire (4), turn ignition
switch to ON position and check that “ABS” warning lamp
indicates normal DTC (DTC 12) referring to “DIAGNOSTIC
TROUBLE CODE (DTC) TABLE” in this section.
8) Turn ignition switch to OFF position.

ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE) 6-1-5
Fuel Pressure Relief Procedure
After making sure that engine is cold, relief fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T vehicle), set parking brake, and
block drive wheels.
2) Remove fuel pump relay (1) from its connector.
3) Remove fuel filler cap to release fuel vapor pressure in fuel
tank and then reinstall it.
4) Start engine and run it till it stops for lack of fuel. Repeat
cranking engine 2 – 3 times of about 3 seconds each time to
dissipate fuel pressure in lines. Fuel connections are now
safe for servicing.
5) Upon completion of servicing, install fuel pump relay to relay
box.
Fuel Leakage Check Procedure
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump)
and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pres-
sure to fuel line (till fuel pressure is felt by hand placed on
fuel return hose).
2) In this state, check to see that there are no fuel leakages
from any part of fuel system. CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.
