CAUTION:

Because vacuum hose contains a check valve, it must be installed in the correct direction. Refer to
the stamp or label to confirm correct installation. Brake booster will not operate normally if hose is
installed in the wrong direction.

Insert vacuum hose at least 24 mm (0.94 in).

Do not use lubricating oil during assembly.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, suspend cylinder body with wire so as not to stretch
brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shim and inner shim cover as a set when replacing brake pads.

Keep rotor clean from brake fluid.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer toBR-32, "
BRAKE BURNISHING PROCEDURE" .
Removal and Installation of Brake PadBFS000BZ
REMOVAL
1. Remove tyres from vehicle.
2. Remove lower sliding pin bolt.

ers, shims, and shim cover from torque member.
CAUTION:
When removing pad retainers from torque member, lift pad
retainers in the direction by the arrow (shown in the figure)
so as not to damage it.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based
grease to the both sides of inner shim and outer shim, install
inner shim and inner shim cover to inner pad and outer shim to
outer pad.

direction.
2. Install pad retainers and pads to torque member.
CAUTION:
Securely assemble pad retainers so that they are not being
lifted up from torque member.
3. Press in piston until pads can be installed, and then install cylin-
der body to torque member.
NOTE:
Using a disc brake piston tool (commercial service tool) to easily
press piston in.
CAUTION:
When replacing pads with new ones, press in piston until
pads can be installed. In this case, carefully monitor brake fluid level in reservoir tank because
brake fluid will return to master cylinder reservoir tank.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-26, "

For Fast and Accurate DiagnosisBFS000E6
PRECAUTIONS FOR DIAGNOSIS

Be sure to check the procedures of “How to Perform Trouble Diagnosis” in advance. Refer to GI-4, "Gen-
eral Precautions" .

Always adjust the neutral position of steering angle sensor before driving when removing and installing
ABS actuator and electric unit (control unit), steering angle sensor, suspension parts and adjusting align-
ment. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

Always erase memory after completing trouble diagnosis. Refer to BRC-58, "ERASE MEMORY" .

When inspection of the continuity or voltage between modules or units is performed, check connector ter-
minals for disconnection, looseness, bend, or collapse. Repair or replace applicable part if any non-stan-
dard condition is detected.

Intermittent malfunctions may be caused by a poor connection in the harness, connectors, and terminals.
Move harnesses, harness connectors, and terminals by hand to make sure all connections are solid and
undamaged.

Do not to forcibly extend any connector terminal if a circuit tester is used for the check.

The symptom shown in the table may occur, but the system is operating normally.
Symptom Symptom description Result
Motor operation soundThis is the operation sound of the motor in the actuator and electric unit.Slight
sound may occur during VDC, TCS and ABS operation.
Normal
Just after the engine starts, the motor operating noise may be heard. This is a
normal status of the system operation check.
System operation check soundWhen engine starts, “click” sound may be heard from engine room. This is nor-
mal status of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp ON)TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when downshifting, or when fully
depressing accelerator pedal.
Normal
Cancel the VDC/
TCS function for
the inspection on
a chassis dyna-
mometer. Before the speed meter inspection, push VDC OFF switch to cancel the VDC/
TCS function.
When accelerator pedal is depressed on a chassis dynamometer (front wheel
fixing type), the vehicle speed will not increase. This is normal. It is result of
TCS being activated by stationary front wheels. The warning lamp may also
turn on to show “sensor system malfunction” in this case. This is also normal,
and is the result of the stationary front wheels being detected. Restart engine,
and drive the vehicle at 30 km/h (19 MPH) or more to make sure that the warn-
ing lamp no longer turns on.
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads or
gravel roads, the stopping distance is sometimes longer for vehicles equipped
with ABS. Therefore, when driving on such roads, drive at a sufficiently
reduced speed to be safe.Normal
Sluggish feelDepending on road conditions, the driver may have a sluggish feel. This is
because traction control, which controls engine and brakes to achieve optimal
traction, has the highest priority (for safety). As a result sometimes the driver
has a less slight sluggish feel in response than usual acceleration feel.Normal

CVT SYSTEM

TCM FunctionBCS001G2
The function of the TCM is to:

Receive input signals sent from various switches and sensors.

Determine required line pressure, shifting point, and lock-up operation.

Send required output signals to the step motor and the respective solenoids.
CONTROL SYSTEM OUTLINE
The CVT senses vehicle operating conditions through various sensors. It always controls the optimum shift
position and reduces shifting and lock-up shocks.

Step Motor
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used right before the non-standard condition occurred.
CVT Lock-up Select Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid is turned OFF to
cancel the lock-up.
TCM Power Supply (Memory Back-up)
Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for
controlling) from the battery is not supplied to TCM. Normal statues is restored when turning the ignition switch
OFF to ON after the normal power supply.
How to Perform Trouble Diagnosis for Quick and Accurate RepairBCS001GG
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, PNP
switch and provides shift control or lock-up control via CVT solenoid
valves.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II or a circuit tester connected should be performed.
Follow the CVT-26, "
WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSHEET” as
shown on the example (Refer to CVT-27
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
