Brake Fluid InspectionS7RS0B0206035
1) Check around master cylinder and reservoir for fluid leakage. If found leaky, correct.
2) Check fluid level. If fluid level is lower than the minimum level of
reservoir, refilling is necessary. Fill reservoir with
specified brake fluid.
For the details, refer to “Brake Fluid Level Inspection
in Section 4A”.
CAUTION!
Since brake system of this vehicle is factory-
filled with brake fluid indicated on reservoir
tank cap, do not use or mix different type of
fluid when refilling; otherwise serious
damage will occur.
Do not use old or used brake fluid, or any
fluid from an unsealed container.

Brake fluid
Refer to reservoir cap of brake master cylinder.
Brake Fluid ReplacementS7RS0B0206017
Change brake fluid as follows.
Drain existing fluid from brake system completely, fill
system with specified fluid and carry out air purge
operation.
For air purging procedure, refer to“Air Bleeding of Brake
System in Section 4A”.
Brake Lever and Cable InspectionS7RS0B0206018
1) Inspect brake cable for damage and smooth movement.
Replace cable if it is in deteriorated condition. 2) Check tooth tip of each notch for damage or wear. If
any damage or wear is found, replace parking lever.
3) Check parking brake lever for proper operation and stroke, and adjust it if necessary.
For checking and adjusting procedures, refer to
“Parking Brake Inspection and Adjustment in Section
4D”.
Parking brake lever stroke
“a”: 4 – 9 notches (with 200 N (20 kg, 44 lbs) of pull
pressure)
Clutch Fluid InspectionS7RS0B0206019
1) Check clutch system for evidence of fluid leakage. Repair leaky point if any.
2) Check reservoir for fluid level referring to “Clutch
Fluid Level Inspection in Section 5C”.
If fluid is lower than minimum level of reservoir, refill
reservoir with specified brake fluid indicated on
reservoir cap.

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.

Road TestS7RS0B5104011
This test is to check if upshift, downshift and lock-up take place at specified speeds while actually driving vehicle on a
level road.
WARNING!
• Carry out test in very little traffic area to prevent an accident.
• Test requires 2 persons, a driver and a tester.

1) Warm up engine.
2) With engine running at idle, shift select lever “D” range.
3) Accelerate vehicle speed by depressing accelerator pedal gradually.
4) While driving in “D” range, check if gear shift and lock-up occur properly as shown in “Automatic Gear Shift Table”.

Troubleshooting
Time Lag TestS7RS0B5104015
This test is to check conditions of clutch, brake and fluid pressure. “Time lag” means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range an d measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 sec.
NOTE
• When repeating this test, be sure to wait at least one minute after select lever is shifted back to “N”
range.
• Engine should be warmed up fully for this test.
• Repeat test 3 times and take average of those data for final time lag data.
