Precautions in Diagnosing Trouble
S3RH0B5100002
• Don’t disconnect couplers from TCM and/or ECM,
battery cable from battery, TCM and/or ECM ground
wire harness from engine or main fuse before
checking the diagnosis information stored in TCM
and/or ECM memory.
Such disconnection will clear memorized information
in TCM and/or ECM memory.
• 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
(instruction) 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 in related manual” before
inspection and observe what is written there.
• TCM and/or ECM replacement when substituting a
known-good TCM and/or ECM, check that all relays
and actuators have resistance of specified value.
Neglecting this check may result in damage to good
TCM and/or ECM.
Precautions for Disassembly and Reassembly
S3RH0B5100003
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”.
• 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 ATF to wash the friction plates 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.
• A new friction plates should be soaked in ATF at least
2 hours before use.
