DTC CheckS7RS0B1104003
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on On-
Board Diagnostic (OBD) System”.
• The MIL is turned on when the ECM and/or TCM detect malfunction(s). Each ECM and
TCM stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs th e DTC to the scan
tool.
Therefore, check both of the ECM and TCM
for any DTC with the SUZUKI scan tool
because the DTC stored in ECM and TCM
is not read and displayed at a time.
However, each of the ECM and TCM needs
not to be checked with the generic scan
tool because the DTC stored in ECM and
TCM is read and displayed at a time.

Using Scan Tool
1) Prepare OBD generic scan tool or SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to DLC (1) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch ON and confirm that MIL lights.
4) Read DTC, pending DTC and freeze frame data according to instructions displayed on scan tool and
print them or write them down. Refer to scan tool
operator’s manual for further details.
If communication between scan tool and ECM is not
possible, check if scan tool is communicable by
connecting it to ECM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. If connector and
circuit are OK, check that power supply and ground
circuits of ECM and DLC are in good condition
referring to “ECM Power and Ground Circuit Check”. 5) After completing the check,
turn ignition switch OFF
and disconnect scan tool from data link connector.
Without Using Scan Tool (Hong Kong Model) 1) Turn ignition switch to OFF position.
2) Using service wire, ground diagnosis switch terminal (1) of diagnosis connector (2).
3) Turn ON ignition switch and check DTC displayed on
odometer (3) of combination meter.
When more than 2 DTCs are stored in memory,
blinking for each DTC star ts with the smallest DTC
number in increasing order. Also, DTC is indicated
repeatedly until the ignition switch is turned OFF or
disconnect service wire.
NOTE
When no DTC is detected, display on
odometer of combinatio n meter is “0000”.

4) After completing the check, turn ignition switch to
OFF position and disconnect service wire from
diagnosis connector.

S7RS0B1104039
System Description
ECM measures the angle of the crankshaft based on the pulse signal from the CKP sensor and CMP sensor for each
cylinder. If it detects a large change in the angle speed of the crankshaft, it concludes occurrence of a misfire. When
the number of misfire is counted by ECM beyond the DTC de tecting condition, it determines the cylinder where the
misfire occurred and output it as DTC.

Engine Cooling System
General Description
Cooling System DescriptionS7RS0B1601001
The cooling system consists of the radiator cap, radiator, coolant reservoir, hoses, water pump, cooling fan and
thermostat. The radiator is of tube-and-fin type.
Coolant DescriptionS7RS0B1601002
WARNING!
• Do not remove radiator cap to check engine coolant level; check coolant visually at the see-through coolant reservoir. Coolant should be added only to reservoir as necessary.
• As long as there is pressure in the cooling system, the temperature can be considerably higher than the boiling temperature of the solution in the radiator without causing the solution to boil. Removal
of the radiator cap while engine is hot and pressure is high will cause the solution to boil
instantaneously and possibly with explosive force, spewing the solution over engine, fenders and
person removing cap. If the solution contains flammable anti-freeze such as alcohol (not
recommended for use at any time), there is also the possibility of causing a serious fire.
• Check to make sure that engine coolant temperature is cold before removing any part of cooling system.
• Also be sure to disconnect negative cable from battery terminal before removing any part.

The coolant recovery system is standard. The coolant in the radiator expands with heat, and the coolant is overflowed
to the reservoir.
When the system cools down, the coolant is drawn back into the radiator.
The cooling system has be en filled with a quality coolant that is a 50/50 mixture of water and ethylene glycol
antifreeze.
This 50/50 mixture coolant solution provides freezing protection to –36 °C (–33 °F).
• Maintain cooling system freeze protection at –36 °C (–33 °F) to ensure protection against corrosion and loss of
coolant from boiling. This should be done even if freezing temperatures are not expected.
• Add ethylene glycol base coolant when coolant has to be added because of coolant loss or to provide added protection against freezing at temperature lower than –36 °C (–33 °F).
NOTE
• Alcohol or methanol base coolant or plain water alone should not be used in cooling system at any
time as damage to cooling system could occur.
• Coolant must be mixed with deminerated water or distilled water.

Coolant Level CheckS7RS0B1606002
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if radiator
cap is taken off too soon.

To check level, lift hood and look at “see-through”
coolant reservoir.
It is not necessary to remove radiator cap to check
coolant level.
When engine is cool, check coolant level in reservoir (1).
A normal coolant level should be between FULL mark
(2) and LOW mark (3) on reservoir (1).
If coolant level is below LOW mark (3), remove reservoir
cap (4) and add proper coolant to reservoir to bring
coolant level up to FULL mark (2).
NOTE
If proper quality antifreeze is used, there is
no need to add extra inhibitors or additives
that claim to improve system. They may be
harmful to proper operation of system, and
are unnecessary expense.

Precautions
Precautions in Diagnosing TroubleS7RS0B5100001
• Do not disconnect couplers from TCM, battery cable from battery, TCM ground wire harness from engine or
main fuse before checking the diagnostic information
(DTC, freeze frame data, etc.) stored in TCM memory.
Such disconnection will clea r memorized information
in TCM memory.
• Diagnostic information stored in TCM memory can be cleared as well as checked by using SUZUKI scan
tool or generic scan tool. 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.
It is indistinguishable wh ich module turns on MIL
because not only ECM but also TCM turns on MIL.
Therefore, check both ECM and TCM for DTC when
MIL lights on.
When checking TCM for DTC, keep in mind that DTC
is displayed on the scan tool as follows depending on
the scan tool used.
– SUZUKI scan tool displays DTC detected by TCM.
– Generic scan tool displays DTC detected by each of ECM and TCM simultaneously.
• Using SUZUKI scan tool the diagnostic information stored in TCM memory can be checked and cleared
as well. Before its use, be sure to read Operator’s
Manual supplied with it carefully to have good
understanding of its functions and usage.
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• TCM replacement
– When substituting a known-good TCM, check that all relays and actuators have resistance of
specified value.
Neglecting this check may result in damage to good
TCM.
• Communication of ECUs , ECM, TCM, ABS control
module, keyless start control module and BCM is
established by CAN (Controller Area Network).
Therefore, handle CAN communication line with care
referring to “Precaution for CAN Communication
System in Section 00”.
Precautions for Disassembly and ReassemblyS7RS0B5100002
When repairing automatic transaxle, it is necessary to
conduct the on-vehicle test to investigate where the
cause of the trouble lies first.
Then whether overhaul should be done or not is
determined. If the transaxle is disassembled without
such preliminary procedure, not only the cause of the
trouble would be unknown, but also a secondary trouble
may occur and often time would be wasted.
As the automatic transaxle consists of high precision
component, the following cautions should be strictly
observed when handling its parts in disassembly and
reassembly.
• Disassembling valve body assembly is prohibited
essentially. However, a few parts can be
disassembled. When disassembling valve body
component parts, confirm whether their parts are
allowed to disassemble or not referring to “Valve Body
Assembly Disassembly and Reassembly”.
• When component part of forward clutch, direct clutch, 2nd brake and/or O/D and 2nd coast brake, namely
clutch disc, brake disc, retaining plate and/or
separator plate, have been replaced, all learned
contents, which have been stored in TCM memory by
executing learning control, should be initialized
referring to “Learning Control Initialization”.
• Make sure to wash dirt off from the transaxle so that no such dirt will enter the transaxle during
dismounting and remounting.
• Select a clean place free from dust and dirt for overhauling.
• Place a rubber mat on the work bench to protect parts from damage.
• Work gloves or shop cloth should not be used. (Use a nylon cloth or a paper towel.)
• When separating the case joint, do not pry with a screwdriver or such but tap with a plastic hammer
lightly.
• Make sure to wash dirt off from the transaxle so that no such dirt will enter the transaxle during
disassembly and reassembly.
• Wash the disassembled parts in ATF (Automatic Transaxle Fluid) or kerosene (using care not to allow
ATF or kerosene to get on your face, etc.) and confirm
that each fluid passage is not clogged by blowing air
into it. But use kerosene to wash the discs, resin
washers and rubber parts.
• Replace each gasket, oil seal and O-ring with a new one.
• Apply ATF to sliding or rotating parts before
reassembly.
