Freeze Frame Data Clearance :
The freeze frame data is cleared at the same time as clearance of
diagnostic trouble code (DTC).
DATA LINK CONNECTOR (DLC)
DLC (1) is in compliance with SAEJ1962 in its installation posi-
tion, the shape of connector and pin assignment.
Serial data line (K line of ISO 9141) is used for SUZUKI scan tool
(Tech-1) or generic scan tool to communicate with ECM, TCM,
ABS control module and Air bag SDM.
SUZUKI serial data line is used for SUZUKI scan tool (Tech -1) to
communicate with immobilizer control module.FRAME

tion, the shape of connector and pin assignment.
Serial data line (K line of ISO 9141) is used for SUZUKI scan tool

PRECAUTION IN DIAGNOSING TROUBLE
Do not disconnect couplers from ECM, battery cable from battery, ECM ground wire harness from engine or
main fuse before confirming diagnostic information (DTC, freeze frame data, etc.) stored in ECM memory.
Such disconnection will erase memorized information in ECM memory.
Diagnostic information stored in ECM memory can be cleared as well as checked by using SUZUKI scan
tool (Tech-1) or generic scan tool (Vehicle with immobilizer indicator lamp). Before using scan tool, read its
Operator’s (Instruction) Manual carefully to have good understanding as to what functions are available and
how to use it.
Priorities for diagnosing troubles (Vehicle with immobilizer indicator lamp).
If two or more DTCs are stored, proceed to the flow table of the DTC which has detected earliest in the order
(it can be identified by referring to freeze frame data) and follow the instruction in that table.
If no instructions are given, troubleshoot diagnostic trouble codes according to the following priorities.
–Diagnostic trouble codes (DTCs) other than DTC P0171/P0172 (Fuel system too lean/too rich), DTC
P0300/P0301/P0302/P0303/P0304 (Misfire detected) and DTC P0400 (EGR flow malfunction)
–DTC P0171/P0172 (Fuel system too lean/too rich) and DTC P0400 (EGR flow malfunction)
–DTC P0300/P0301/P0302/P0303/P0304 (Misfire detected)
Be sure to read “Precautions for Electrical Circuit Service” in Section 0A before inspection and observe what
is written there.
ECM Replacement
When substituting a known-good ECM, check for following conditions. Neglecting this check may cause
damage to a known-good ECM.
–Resistance value of all relays, actuators is as specified respectively.
–MAP sensor and TP sensor are in good condition and none of power circuits of these sensors is shorted
to ground.AMBIENT
TEMPERATURETIME TO CUT POWER TO ECM
Over 0°C (32°F) 60 sec. or longer
Under 0°C (32°F) Not specifiable. Select a place with
temperature higher than 0°C (32°F).

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
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).

WARNING:
For vehicles equipped with Supplement 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 DIAGNOSIS 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
PRECAUTIONS under PRECAUTIONS 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 unin-
tentional activation of the system or could render the system inoperative. Either of these two condi-
tions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
