• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• ECM replacement: When substituting a known-good ECM, check for the
following conditions. Neglec ting this check may cause
damage to a known-good ECM.
– Resistance value of all relays, actuators is as specified respectively.
– MAP sensor, A/C refrigerant pressure sensor and TP sensor are in good condition and none of power
circuits of these sensors is shorted to ground.
• Communication of ECM, BCM, ABS/ESP ® control
module, combination meter, keyless start control
module, steering angle sensor (ESP ® model) and
TCM (A/T model), is esta blished by CAN (Controller
Area Network). (For more detail of CAN
communication for ECM, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”.
• Immobilizer transponder code registration after
replacing ECM
When ECM is replaced with new one or with another
one, make sure to register immobilizer transponder
code to ECM correctly according to “Procedure after
ECM Replacement in Section 10C”.Precautions of ECM Circuit InspectionS7RS0B1100003
• ECM connectors are waterproofed. Each terminal of the ECM connectors is sealed up with the grommet.
Therefore, when measuring ci rcuit voltage, resistance
and/or pulse signal at ECM connector, do not insert
the tester’s probe into th e sealed terminal at the
harness side. When measuring circuit voltage,
resistance and/or pulse signal at ECM connector,
connect the special tool to the ECM connectors. And,
insert the tester’s probe into the special tool’s
connectors at the harness side, and then measure
voltage, resistance and/or pulse signal. Or, ECM and
its circuits may be damaged by water.
• Wire colors of the special tool’s connectors are different from the ones of the ECM connectors.
However, the circuit arrangement of the special tool’s
connectors is same as the one of the ECM
connectors. Therefore, measure circuit voltage and
resistance by identifying the terminal location subject
to the measurement.
Precautions of Electric Throttle Body System
Calibration
S7RS0B1100004
After performing one of works described below, it is
necessary to re-register the completely closed throttle
valve reference position stored in memory of ECM. (For
detailed information, refer to “Description of Electric
Throttle Body System Calibration”.) For the procedure to
register such data in ECM, refer to “Electric Throttle
Body System Calibration in Section 1C”.
• To shut off backup power of ECM for such purposes of battery replacement or “DOME” fuse removal
• To erase DTCs P0122, P01 23, P0222, P0223, P2101,
P2102, P2103, P2111, P2112, P2113, P2119, P2123,
P2127, P2128, P2135 and/or P2138
• To replace ECM
• To replace throttle body and/or accelerator pedal position (APP) sensor assembly
General Description
Statement on Cleanliness and CareS7RS0B1101001
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the thousands of an
millimeter (ten thous ands of an inch).
Accordingly, when any internal engine parts are
serviced, care and cleanliness are important.
It should be understood that proper cleaning and
protection of machined surfaces and friction areas is part
of the repair procedure. This is considered standard
shop practice even if not specifically stated.
• A liberal coating of engine oil should be applied to friction areas during assembly to protect and lubricate
the surfaces on initial operation. • Whenever valve train components, pistons, piston
rings, connecting rods, rod bearings, and crankshaft
journal bearings are removed for service, they should
be retained in order.
At the time of installation, they should be installed in
the same locations and with the same mating
surfaces as when removed.
• Battery cables should be disconnected before any major work is performed on the engine.
Failure to disconnect cables may result in damage to
wire harness or other electrical parts.

Precautions
Precautions in Diagnosing TroublesS7RS0B4500001
To ensure that the trouble diagnosis is done accurately
and smoothly, observe the following and follow “ABS
Check”.
• Diagnostic information stored in ABS cont rol module
memory can be cleared as well as checked by using
SUZUKI scan tool. Before us ing scan tool, read its
Operator’s (Instruction) Manual carefully to have good
understanding as to what functions are available and
how to use it.
• If the vehicles was operated in any of the following ways, ABS warning light may light momentarily but
this does not indicate anything abnormal in ABS.
– The vehicle was driven with parking brake pulled.
– The vehicle was driven with brake dragging.
– The vehicle was stuck in mud, sand, etc.
– Wheel spin occurred while driving.
– Wheel(s) was rotated while the vehicle was jacked up.
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• Be sure to use the trouble diagnosis procedure as described in “ABS Check”. Failure to follow it may
result in incorrect diagnosis. (Some other diagnosis
trouble code may be stored by mistake in the memory
of ABS control module during inspection.)
• When disconnecting ABS co ntrol module connector
(1), pull down lock lever (2) of connector.
When connecting, set the connector on ABS control
module assembly and pull up the lock lever (2) until it
locks. • Communication of ECM,
BCM, ABS control module,
keyless start control module (if equipped), and
combination meter is established by CAN (Controller
Area Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00”
before inspection and handle CAN communication
line.
Precautions in On-Vehicle ServiceS7RS0B4500002
When connector is connected to ABS control module
assembly, do not disconnect connectors of sensors with
ignition switch ON. Otherwise, DTC will be set in ABS
control module.
Precautions in Hydraulic Unit Operation CheckS7RS0B4500003
ABS hydraulic unit / control module assembly function is
checked by correct wheel lock / release condition when
brake pressure is pressurized / depressurized using
SUZUKI scan tool. The hydraulic unit operation check
referring to “ABS Hydraulic Unit Operation Check”
should be performed to confirm the correct brake pipe
connection in the following cases.
• ABS hydraulic unit / cont rol module assembly was
replaced.
• Brake pipe and/or hose ware replaced.

the lock lever (2) until it locks. • Communication of ECM, BCM, ESP
® control module,
keyless start control module (if equipped), steering
angle sensor and combination meter is established by
CAN (Controller Area Network).
Therefore, be sure to read “Precautions for Installing
Mobile Communication Equipment in Section 00”
before inspection and handling CAN communication
line.
Precautions in On-Vehicle ServiceS7RS0B4600002
When connector is connected to ESP ® hydraulic unit /
control module assembly, do not disconnect connectors
of sensors with ignition switch ON. Otherwise, DTC will
be set in ESP ® control module.
Precautions in Hydraulic Unit Operation CheckS7RS0B4600003
ESP® hydraulic unit / control module assembly function
is checked by correct wheel lock / release condition
when brake pressure is pressurized / depressurized
using SUZUKI scan tool. The hydraulic unit operation
check referring to “ESP ® Hydraulic Unit Operation
Check” should be performed to confirm the correct brake
pipe connection in the following cases.
• ESP® hydraulic unit / contro l module assembly was
replaced.
• Brake pipe and/or hose were replaced.
Precautions in Sensor CalibrationS7RS0B4600004
ESP ® control module stores calibration points data of yaw rate / G sensor assembly and master cylinder pressure
sensor. Steering angle sensor stores calibration point data of itself.
TCS and stability control system use these sets of data.
When the following operation is done, sensor calibration should be performed since the original calibration points are
deleted.
