Precautions for Removing Battery Terminal

INFOID:0000000009972284

• When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.

• For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.

Precaution for Brake System

INFOID:0000000009972283

WARNING:

Since dust covering the front and rear brakes has an affect on human body, the dust must be removed
with a dust collector. Never splatter the dust with an air blow gun.
• Brake fluid use refer to

MA-10, "Fluids and Lubricants"

• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off

immediately and wash with water if it gets on a painted surface.

• Always confirm the specified tightening torque when installing the brake pipes.
• After pressing the brake pedal more deeply or harder than normal driving, such as air bleeding, check each

item of brake pedal. Adjust brake pedal if it is outside the standard value.

• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause

improper operation.

• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with a crow-

foot (A) and torque wrench (B).

• Turn the ignition switch OFF and disconnect the ABS actuator and

electric unit (control unit) harness connector or the battery negative
terminal before performing the work.

• Check that no brake fluid leakage is present after replacing the

parts.

Precaution for Brake Control System

INFOID:0000000009651346

• Always perform a pre-driving check to drive the vehicle.
• Always check speed and safety while driving the vehicle.
• To operate CONSULT while driving, more than one person is required to be in the vehicle to avoid interfer-

ence to driving and ensure safety.

• Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC function, TCS func-

tion, ABS function EBD function or brake limited slip differential (BLSD) function operates. This is not a mal-
function because it is caused by VDC function, TCS function, ABS function EBD function or brake limited slip
differential (BLSD) function that is normally operated.

• When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor

operating noise may be heard from engine compartment. This is normal condition.

• Brake stopping distance may become longer than models without ABS function depending on the road con-

ditions, when ABS function is operated on slippery road like rough road, gravel road or snowy road.

PRECAUTIONS

• When a malfunction is indicated, always collect information from the customer about conditions of occur-

rence, estimate cause and perform operation. Check brake booster operation, brake fluid level and brake
fluid leakage, as well as electrical system.

• The optimum performance is achieved by control for VDC function, TCS function, ABS function EBD func-

tion and brake limited slip differential (BLSD) function when all of brakes, suspensions and tires installed on
the vehicle are the specified size and parts. Brake performance and controllability may be negatively
affected when other parts than the specified are installed.

• Brake stopping distance may become longer and steering stability may be negatively affected, when tires in

different size and combination or other parts than the specified are used.

• When a radio (including wiring), antenna and antenna lead line are located near ABS actuator and electric

unit (control unit), a malfunction or improper operation may occur for the control of VDC function, TCS func-
tion, ABS function EBD function and brake limited slip differential (BLSD) function.

• When the following items are replaced by other parts than genuine parts or modified, ABS warning lamp,

brake warning lamp and VDC warning lamp may turn ON, and the control may not operate normally for VDC
function, TCS function, ABS function EBD function and brake limited slip differential (BLSD) function.

- Suspension component parts (shock absorber, spring, bushing and others)
- Tire and wheel (other than the specified size)
- Brake component parts (brake pad, disc rotor, brake caliper and others)
- Engine component parts (ECM, muffler and others)
- Body reinforcement component parts (rollover bar, tower bar and others)
• When suspension, tire and brake component parts are excessively worn or deteriorated and the vehicle is

driven, ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON, and the control may
not operate normally for VDC function, TCS function, ABS function EBD function and brake limited slip differ-
ential (BLSD) function.

• ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON, when only front wheel or rear

wheel is rotated using a free roller. This is not a malfunction, because it is caused by wheel speed difference
between wheel that is rotated and wheel that is not rotated. In this case, perform self-diagnosis, check self-
diagnosis results, and erase memory.

• When power supply voltage is not normal, ABS warning lamp, brake warning lamp and VDC warning lamp

turn ON. ABS actuator and electric unit (control unit) stops control for VDC function, TCS function, ABS func-
tion EBD function and brake limited slip differential (BLSD) function. Ordinary brake operates. After power
supply returns to normal, ABS warning lamp, brake warning lamp and VDC warning lamp turn OFF. The con-
trol becomes operative for VDC function, TCS function, ABS function EBD function and brake limited slip dif-
ferential (BLSD) function.

• Brake pedal vibrates and operation sound occurs during sudden acceleration and cornering, when VDC

function, TCS function or brake limited slip differential (BLSD) function is operated. This is not a malfunction
because it is caused by VDC function, TCS function or brake limited slip differential (BLSD) function that is
operated normally.

• VDC warning lamp may turn ON and VDC function, TCS function and brake limited slip differential (BLSD)

function may not normally operate, when driving on a special road the is extremely slanted (bank in a circuit
course). This is not a malfunction if the status returns to normal for VDC function, TCS function and brake
limited slip differential (BLSD) function after the engine is started again. In this case, perform self-diagnosis,
check self-diagnosis results, and erase memory.

• A malfunction in yaw rate/side G sensor system may be detected when the vehicle sharply turns during a

spin turn, acceleration turn or drift driving while VDC function, TCS function and brake limited slip differential
(BLSD) function are OFF (VDC OFF switch is pressed and VDC OFF indicator lamp is in ON status). This is
not a malfunction if the status returns to normal for VDC function, TCS function and brake limited slip differ-
ential (BLSD) function after the engine is started again. In this case, perform self-diagnosis, check self-diag-
nosis results, and erase memory.

Precaution for Harness Repair

INFOID:0000000009651347

• Solder the repair part, and wrap it with tape. [Twisted wire fray

must be 110 mm (4.33 in) or less.]

• Never bypass the repair point with wire. (If it is bypassed, the turn-

out point cannot be separated and the twisted wire characteristics
are lost.)
