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 system (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
Immobilizer indicator lamp
Knock sensor

FUEL DELIVERY SYSTEM
FUEL PRESSURE INSPECTION
1) Relieve fuel pressure in fuel feed line referring to “Fuel Pres-
sure Relief Procedure” in Section 6.
2) Disconnect fuel feed hose from fuel delivery pipe.
3) Connect special tools and hose between fuel delivery pipe
and fuel feed hose (1) as shown in figure, and clamp hoses
securely to ensure no leaks occur during checking.
Special tool
(A) : 09912-58441
(B) : 09912-58431
(C) : 09912-58490
4) Check that battery voltage is above 11 V.
5) Turn ignition switch ON to operate fuel pump and after 2 sec-
onds turn it OFF. Repeat this 3 or 4 times and then check
fuel pressure.
Fuel pressure specification WARNING:
Be sure to perform work in a well-ventilated area and
away from any open flames, or there is a risk of a fire
breaking out.
CAUTION:
A small amount of fuel may be released when fuel hose is
disconnected. Place container under the joint with a
shop cloth so that released fuel is caught in container or
absorbed in cloth. Place that cloth in an approved con-
tainer.

REMOVAL
1) Disconnect battery negative cable at battery.
2) Disable air bag system, referring to “Disabling The Air Bag
System” in Section 10B if equipped.
3) Disconnect ECM (1) and TCM (2) (if equipped) connectors.
4) Remove bolt and nuts, remove ECM and TCM (if equipped).
INSTALLATION
Reverse removal procedure noting the following:
Connect connectors to ECM and TCM (if equipped) securely.
MANIFOLD ABSOLUTE PRESSURE SENSOR (MAP

INSPECTION
Check MAP sensor referring to “MAP Sensor Individual Check” in
DTC P0105 (No.11) Flow Table. If malfunction is found, replace.CAUTION:
As ECM consists of precision parts, be careful not to
expose it to excessive shock.
