2000 SUZUKI SWIFT battery

TYPE 1 TYPE 2
BODY ELECTRICAL SYSTEM 8-3
KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.

ECT SENSOR
INSPECTION
1) Warm up ECT sensor (1) observing resistance between sensor
terminal (2) and sensor unit (1). Resistance should be de-
creased with increase of its temperature.
2) Check resistance between sensor terminal (2) and sensor unit
(1). If check result is not as specified below, replace sensor.

TRANSMITTER
REPLACEMENT OF THE BATTERY
If the transmitter becomes unreliable, replace the battery.
As the battery power is consumed, the operation distance will be
shorter.
1) Put the edge of a coin or a flat blade screw driver in the slot of
the transmitter and pry it open.
2) Replace the battery (lithium disc-type CR2025 or equivalent) so
its (+) terminal faces the “+” mark of the transmitter.
CAUTION:
Use care not to allow grease or dirt to be attached on the
printed circuit board and the battery.
3) Close the transmitter firmly.
4) Make sure the door locks can be operated with the transmitter.
NOTE:

To prevent theft, be sure to break the transmitter before
discarding it.

Dispose of the used battery properly according to appli-
cable rules or regulations. Do not dispose of lithium bat-
teries with ordinary household trash.

SECTION 8G
IMMOBILIZER CONTROL 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:

Whether the immobilizer indicator lamp is used in the particular vehicle or not depends on specifica-
tions. If there is a monitor coupler in the engine room near the left strut assembly, the vehicle is not
equipped with immobilizer indicator lamp and if there isn’t, it is equipped with immobilizer indicator
lamp.

For the descriptions (items) not found in this section, refer to the section 8G of the Service Manual men-
tioned in FOREWORD of this manual.

8G-6 IMMOBILIZER CONTROL SYSTEM
DIAGNOSIS
ECM and Immobilizer Control Module have on-board diagnostic
system (a system self-diagnosis function) as described previously.
Investigate where the trouble is by referring to “DIAGNOSTIC
FLOW TABLE” and “DIAGNOSTIC TROUBLE CODE TABLE” on
later pages.
PRECAUTIONS IN DIAGNOSING TROUBLES
[PRECAUTIONS IN IDENTIFYING DIAGNOSTIC TROUBLE
CODE]
ECM


Before identifying diagnostic trouble code indicated by malfunc-
tion indicator lamp, don’t disconnect couplers from ECM, battery
cable from battery, ECM ground wire harness from engine.
Such disconnection will clear trouble codes for engine and emis-
sion control system stored in memory of ECM.

If abnormality or malfunction lies in two or more areas, malfunc-
tion indicator lamp indicates applicable codes three times each.
And flashing of these codes is repeated as long as diagnosis ter-
minal is grounded and ignition switch is held at ON position.

When ECM detects a trouble in both engine and emission control
system and immobilizer control system, malfunction indicator
lamp indicates trouble codes of both systems alternately while the
ignition switch is turned ON and the diagnosis terminal is
grounded.

Take a note of diagnostic trouble code indicated first.


Before identifying diagnostic trouble code indicated through Su-
zuki scan tool, don’t disconnect couplers from ECM, battery cable
from battery, ECM ground wire harness from engine.
Such disconnection will clear trouble codes for engine and emis-
sion control system stored in memory of ECM.

When ECM detects a trouble in both engine and emission control
system and immobilizer control system, Suzuki scan tool indi-
cates trouble codes of both systems using Suzuki mode of ECM
applications.

Take a note of diagnostic trouble code indicated first.
Immobilizer Control Module

Take a note of diagnostic trouble code indicated first.
