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.

Whenever vehicle is hoisted for any other
service work than oil change, also be sure to
check for oil leakage.
