NOTE:
At this moment, ACC power is supplied.

Open the driver side door.

Open the hood.

Close the driver side door.

Wait at least 3 minutes.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

Precaution for Work

INFOID:0000000010416962

• When removing or disassembling each component, be careful not to damage or deform it. If a component

may be subject to interference, be sure to protect it with a shop cloth.

• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component

with a shop cloth or vinyl tape to protect it.

• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty

area.

• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

PRECAUTIONS

Precautions for Harness Repair

INFOID:0000000010416963

• Solder the repaired area and wrap tape around the soldered area.

NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).

• Bypass connection is never allowed at the repaired area.

NOTE:
Bypass connection may cause CAN communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.

• Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-

tion line.

Precautions for Chassis control

INFOID:0000000010416964

• Do not disassemble the chassis control module.
• Do not reuse if the chassis control module has been dropped.
• Do not perform ACTIVE TEST while driving the vehicle.
• Slight vibrations are felt on the brake pedal and the operation noises occur, when Active Trace Control and

Active Ride Control function operates. This is not a malfunction because it is caused by the functions that
are normally operated.

• Tachometer will rise and engine noise may be noticeable during Active Engine Brake function operation.

This is not a malfunction because it is caused by the function that is normally operated.

• Active Trace Control, Active Ride Control and Active Engine Brake are not always activated in any driving

conditions.

• Chassis control to integrally control the driving system was adopted.
• Chassis control module inputs the necessary information for control from CAN communication and each

switch and integrally controls each system. Refer to the following table for systems controlled and input/out-
put signals.

System Description - Active Engine Brake

INFOID:0000000010416969

Active Engine Brake function can be switched ON/OFF through the "Chassis Control" settings on the vehicle
information display.

• Assist at corners - to lessen the workload of adjusting speed with

brake pedal operations at corners. Active Engine Brake function
adds small amount of deceleration by controlling the CVT gear
ratio depending on the steering input and various sensors. This
benefits to easier traceability at corners.

• Assist at breaking - To enhance braking feel, Active Engine Brake

adds deceleration by shifting the CVT gear ratio to lower side
depending on the driver’s brake pedal operation.

System Description - Active Ride Control

INFOID:0000000010416970

The Active Ride Control function can be turned ON/OFF by turning the VDC OFF switch ON/OFF.

• Engine control - Enhances ride comfort by adding/subtracting

engine torque in an effort to control the front and rear wheel load
balance.

• Engine control - Enhances handling by adding/subtracting engine

torque in an effort to control the front and rear wheel load balance.

• Brake control - Enhances ride comfort by restraining upper body

movement with small amount of brake control when driving on
bumpy roads.

System Description - Active Trace Control

INFOID:0000000010416971

Active Trace Control function controls the braking utilizing the ABS actuator and electric unit (control unit),
depending on cornering condition calculated from driver’s steering input and plural sensors. Active Trace Con-
trol function is aimed to enhance traceability at corners and smooth the vehicle movement to provide confident
driving.

[CHASSIS CONTROL]

Active Trace Control function can be switched ON/OFF through the "Chassis Control" settings on the vehicle
information display. When the Active Trace Control is selected OFF, some functions will be kept ON to assist
driver (for example, avoidance condition).
When the VDC OFF switch is used to turn OFF the VDC system, the Active Trace Control system is also com-
pletely turned OFF.
• Steady cornering - The change of forward and lateral acceleration

is smoothened by applying the necessary amount of brake pres-
sure.

• Transient steering input - Reduces lag of yaw rate against steering

operation.

• Acceleration at corners - Restrains understeer by applying the nec-

essary amount of brake pressure to the inner wheels.

• Quick lane change - achieves stable vehicle behavior at quick

steering operation by applying the necessary amount of brake
pressure to the appropriate wheels.

Precautions for Chassis Control (Engine Brake, Active Ride, and Active Trace)

INFOID:0000000010416974

CHASSIS CONTROL

• Chassis Control will not provide all the necessary controls to replace driver intervention. It is not designed to

prevent loss of control. It is the driver’s responsibility to stay alert, drive safely, keep the vehicle in the travel-
ing lane, and be in control of vehicle at all times.

• Chassis Control is primarily intended for use on well-developed freeways or highways. It may not perform

satisfactorily in certain roads, weather or driving conditions.

• Using Chassis Control under some conditions of road, corner or severe weather could lead to an unex-

pected system operation. In such conditions, driver needs to correct the vehicle's direction with driver's
steering operation to avoid accidents.

• When Chassis Control is operating, avoid excessive or sudden steering maneuvers. Otherwise, you could

lose control of the vehicle.

• Engine Brake Control is designed to enhance braking feel and traceability at corners.
• Active Ride Control is designed to enhance handling and drive comfort.
• Active Trace Control is designed to enhance traceability at corners and smooth vehicle movement for more

confident driving.

• Chassis Control may not function properly under the following conditions:
- During bad weather (rain, fog, snow, wind, etc.).
- When driving on slippery roads, such as on ice or snow, etc.
- When driving on winding or uneven roads.
- When driving with a tire that is not within normal tire conditions (for example, tire wear, low tire pressure,

installation of spare tire, tire chains, non-standard wheels).

- When the vehicle is equipped with non-original steering parts or suspension parts.
• The functions of Chassis Control may or may not operate properly under the following conditions:
- On roads covered with water, dirt or snow, etc.
- On roads where there are sharp curves.

ACTIVE TEST

The active test is used to determine and identify details of a malfunction, based on self-diagnosis test results
and data obtained in the DATA MONITOR. In response to instructions from CONSULT, instead of those from
chassis control module on the vehicle, a drive signal is sent to the actuator to check its operation.

CAUTION:

• Never perform ACTIVE TEST while driving the vehicle.
• Always bleed air from brake system before active test.
• Never perform active test when system is malfunctioning.
NOTE:
• When active test is performed while depressing the brake pedal, the brake pedal depressing stroke may

change. This is not a malfunction.

• During an active test, sometimes a chassis control warning is displayed and the master warning lamp illumi-

nates on the information display in the combination meter; however, this is not a malfunction.
